INSTRUCTIONS FOR SERVICING SUNBEAM RADIANT
CONTROL TOASTER MODELS T20, T20A, &T20B
GENERAL
The New Sunbeam Radiant Control Toaster is a1275 watt electric appliance with its
elements in series and _is to be used on ALTERNATING CURRENT ONLY .It differs from
previous models and other toasters on the market in toasting control principle, in the
method used in raising and lowering the bread, and in the design of the elements.
The Toaster is much less sensitive to differences in freshness or moisture content of the
bread, or to variations in line voltage than previous Toasters, because the toasting
cycle depends entirely upon the amount of heat radiated from the bread being toasted.
When toasting one slice, place it into the slot marked "ONE SLICE ". When toasting two
slices, they should be of uniform freshness to get uniform results.
Attached at the end of this bulletin is acomplete descriptive list of parts and parts
assemblies. These are shown in their relative positions on the detailed illustration on
the back of the parts list. The tools used for servicing the Toaster are shown at the end
of the bulletin.

HOW THE TOASTER OPERATES
Put two slices of bread in the Toaster. The slice in the slot marked "One Slice" will
depress the Trip Lever, causing the Trigger Lever Assembly to close the contact points.
The elements will then heat up, and the expansion of the Center Element wire will allow
the Bread Lifter Assembly to go down slowly under its own weight.
When the bread is toasted, the heat radiated from the outer surface of the bread, in the
slot marked "One Slice", will cause the Thermostatic Blade to snap to "off" position,
causing the contact points to open. Then, as the elements cool, the wire in the Center
Element will contract, and force the Lift Lever Depression Bar down, causing movement of
the Lift Lever Assembly, which forces the Bread Lifter Assembly to slowly raise the
toasted bread.
OPERATING PRINCIPLES
Uniformity of toasting, under varying conditions, such as bread size, moisture content of
bread, voltage, and Toaster temperature, is obtained in this Toaster by having the
Radiant Control Thermostat respond to only the surface temperature of the slice of bread
being toasted. As the bread surface begins to toast, it will rise in temperature, and
this temperature, at every instant, bears aclose relationship to color at the same
instant. In this particular mechanism this surface temperature is measured by the heat
radiated (not conducted) from that surface to the Radiant Control Thermostat. The
Thermostat Assembly is unavoidably affected by atemperature rise due to the heating up
of its surroundings, but it is so designed as to properly compensate for this effect so
as to have anet response to only the heat radiated from the bread surface. Consistent
operation is assured because the Thermostat Blade operates with asnap action. Thus, it
is absolutely free of the effects of friction, since, in its snap motion, it encounters
no resistance, frictional or otherwise, until it moves freely for asufficient distance
to have many times more force available to do the work than is necessary.
Raising or lowering of the bread is obtained by making use of the energy of expansion and
contraction of the Center Element wire. Of course, this movement is very small and is
measured in thousandths of an inch, but more than adequate carriage movement is obtained
by asimple linkage which multiplies this movement approximately 175 times. Only the
movement in the lower range of temperature (below 1000 F.) is used for this purpose since
it is undesirable to apply stress to this wire while at or near the operating temperature
of approximately 1600 F.
The end elements are of unique design for the purpose of increasing the Toaster' s
efficiency. This design possesses much less heat capacity than an element of conventional
type, and consequently permits much faster toasting when the Toaster is cold.

RULES OF GOOD REPAIR PRACTICES
The success of the repair depends upon the repairman' sability in following the rules of
good repair practices. These rules can be summed up as follows:
1. Read the Service Bulletin thoroughly.
2. Know what you are looking for. Never guess. Always investigate the source of
trouble. Ask, if you do not know.
3. Determine troubles by the process of elimination.
4. Every part, no matter how small, has ajob to perform. Do not overlook the
smallest detail.
5. Use the proper tool. Keep tools in efficient working order.
6. Carefully handle smooth, plated, or Bakelite parts to prevent damaging or
scratching.
7. Make the repair like you would want it, if you were the customer.

guide to locate the holes.
D. Replace Screws (30) with Screws used on the Model T20A and T20B Toaster.
E. Change model number to read T20B with stamping dies.

-7-
5. Thermostat Blade -Remove Thermostat Assembly (12) from Toaster and disassemble as
described in section C4. Remove Screws (12X) ,Screw (12U) and Nut (12W) that fasten
Thermostat Blade to Bracket. Locate new Blade (12V) and secure tightly to Upright with
Screws (12X), (12U), Nut (12W) and lock Washer (12Z if Toaster is model T20B)
.
CAUTION :Snap the Blade flat against the Upright ("OFF" Position) .THE ENTIRE CENTER
PORTION OF THE BLADE, BETWEEN POINTS (AAND B) ,MUST LAY FLAT AGAINST THE UPRIGHT FOR
THE BLADE TO BE STABILIZED PROPERLY .(SEE DIAGRAM )If it does not lay flat, adjust by
tapping the bend Cor Don the high side of the Blade. Test Blade to see that entire
center portion of the Blade rises simultaneously and parallel to the Upright when
snapped to "ON" Position. Reassemble the Thermostat Assembly, install in Toaster, and
connect Leads
.
TO STABILIZE BLADE, CLIP AJUMPER WIRE ACROSS THE TWO LEADS ON THE THERMOSTAT, THEN
ADJUST BLADE TO "OFF" POSITION .Insert Plug of Toaster into 110 Volt A. C. Wall
Receptacle and permit the current to flow through the circuit for five minutes. After
stabilizing the Blade, make the adjustments as outlined in Section D. Reassemble
Toaster and test with bread.
Test three consecutive sets of toast in rapid succession. Let Toaster cool and test
another set of toast and compare the color of this set to the three sets. The color
should be the same for all four sets of toast. If toast varies in color, stabilize
blade again and check with bread. Repeat this process until uniform toast is obtained
from tests.
6. Switch Leads -Remove Screw (13), Washer (8), Nut (7) and Washer (8) disconnecting
Switch Lead (21). Replace Lead and reassemble.
7. End Elements -Turning mechanism assembly over, release Guide Wires (9) from Mounting
Plate Assembly. Then turning the mechanism assembly back into position, remove Hex Nut
(7) and Washer (8), then remove Screws (2) lifting End Top Plate (3) with Guide Wires
and Window End Element Assembly (11) off of mechanism, being careful that the Guide
Wires do not get caught in Element Wires and Bread Rack. The Upper

Bus Bar with Insulator (4) is attached to the Element Assembly. Follow the same
procedure to remove Closed End Element Assembly (6) .Be sure to remove Hex Nut (7) and
Washer (8) from Center Element before removing End Top Plate with Guide Wires and
Element Assembly. Be careful of Lower Bus Bar attached to the Element Assembly and
watch that the Guide Wires do not catch into the Elements and Bread Rack. Replace
Element and reassemble.
8. End Element Wires -To replace the Coiled Element Wire (6A) of the End Elements (6 &
11), first remove the burned out Element as described in Section A, disassembly, then
make sure that the Terminal end of the Bus Bar is clean and free of any small pieces
of wire. Straighten Terminal Strips, because the Mica Strip in the center of the
Coiled Element must be perpendicular to the Reflector in order to obtain the proper
heat radiation from the Element. Bend the extreme tip of the new Coiled Element around
Terminal of Bus Bars to hold the Element in place while being Silver Soldered or Spot
Welded. Always connect the end of the Element with the most turns to the bottom
Terminal
.
The Element Wires should be ordered by grade numbers as follows. Grade 2can be used
for Elements graded 1through 3and grade 5for Elements grades 4through 6. Check
replaced Element for grade number stamped on the Reflector Plate.
9. Center Element -Release Guide Wires, then remove Screws (2) and lift Center Element
Assembly (10) with Center Top Plate attached from the mechanism assembly. Replace
Center Element and reassemble.
10. Center Element Wire -To replace the Element Wire (10J) on the Center Element Assembly
(10) place arubber band around the Frame to hold the Mica Strips (10B, IOC, &10H) in
place, then clip each Wire on one side of the Assembly with apair of Cutting Pliers.
Remove the Terminal Screws, Mica (10G) and Porcelain Insulators (10F)
.
To wind new Element Wire (10 J) around Frame, locate Porcelain and Mica Insulator at
top of Frame and insert Terminal Screw of one end of the new Element Wire through
Insulators and secure tightly to Frame with Washer and Nut. To make the winding
process easier, squeeze Frame until each side just barely touches the Reflector. Wind
new Wire around Frame, locating each bend in its proper place. Note that one side
strip has ten slots and the other nine. Locate Porcelain and Mica Insulators and
insert Terminal Screw on other end of Wire -through these Insulators and secure
tightly to Frame with Washer (10E) and Nut (10D). When tightening Terminal Screws,
hold slotted side with an offset Screwdriver to keep it from turning and cutting the
Wire
.
Install Assembly into Toaster and reassemble Toaster. Make bread test and check Bread
Lifter Assembly for proper tension after each cycle. The Bread Lifter Assembly with
bread should take approximately 10 to 12 seconds to raise after Contacts have opened.

-9-
The Coiled Elements should be ordered by Grade Numbers as follows: Grade 2can be
used for Elements graded 1through 3, and Grade 5for Elements graded 4through 6.
Check replaced Element for grade number stamped on the Reflector Plate.
11. Bread Lifter Assembly and Side Frame Assemblies -Turn mechanism assembly bottom
side up and remove Screws (18) releasing Lift Lever Assembly (19) from mechanism.
Unhook Lift Lever Depression Bar (22) from Lift Lever Assembly by sliding Lift Lever
back off to mechanism assembly. Remove Screws (2) releasing Mounting Plate Assembly
(20), then remove Screws (2) freeing Frame Cross Yoke (15). Now lift Bread Lifter
Assembly (17) from slots in Side Frame Assembly L. H. (14) and Side Frame Assembly
R. H. (16), which will finish the complete disassembly of the mechanism assembly.
Replace Bread Lifter Assembly and reassemble.
12. Carriage Counter Balance Spring -The Carriage Counter Balance Spring (3A) is used
in the T20B Toaster to support the weight of the Bread Carriage. To replace this
Spring, remove the old Spring from the End Top Plate (3) and Bread Lifter Assembly
(17) .Replace with new Spring. 3to 4turns of the flat end of the Spring hooks over
the Top End Plate (3) and the looped end hooks in the hole in the Bread Lifter
Assembly (17 )
.
D. ADJUSTMENTS
In most cases it is only necessary to remove End Shell on Control Knob end. This is done
by placing the Toaster bottom side up on asoft cloth, or on Tool No. 1, to prevent
scratching the shell. Remove the screws (six in all), Key Nos. 28 and 30. Remove the
Control Knob (26), lift off the Bottom Cover Assembly (29) and bakelite Base (25). Now
remove only the four Screws (2) at the Control Knob end. Then insert ascrewdriver
between the End Shell and the frame to loosen the End Shell, being careful not to scratch
it. This will expose the main parts of the mechanism.
1. Toast is Too Light Or Too Dark at "Medium" Setting -Set Toaster at Medium and test
with two slices of bread from the same loaf. If complaint is that toast is too dark,
remove Adjustment Knob (26) and turn Adjustment Screw (See Diagram II) in the proper
direction until toast of desired color is obtained. Replace Control Knob with
indicator at Medium. Reverse procedure if complaint is that toast is too light. The
Control Knob has twelve points molded into it so that an adjustment to within 1/24
of aturn can be made.
2.Bread Lifter Assembly Does Not Lower When Bread is Inserted
(a) When toasting single slice make sure user puts bread in slot marked "One
Slice."
(b) Check action of Trip Lever to see that it is not rubbing or binding anywhere,
since excessive friction may prevent Trip Lever from

-10-
Diagram 1Diagram 2
RADIANT CONTROL THERMOSTAT ON SUNBEAM TOASTER MODEL T20, T20A, &T20B

-11 -
rising sufficiently in bread slot when bread is removed. This in turn would keep
the other end (E) (Diagram I) from moving out far enough to allow Trigger (C) to
drop into position shown. The friction might be due to Trip Lever (E) rubbing
guide wires, as there is not sufficient end play at the bearing points for free
action; or the ends of the Trip Lever entering the bearings might not be
straight, thus causing binding. If Trip Lever appears to be free of excessive
friction, then it is likely that clearance indicated by dimension (D) (Diagram
I) is insufficient. To check this clearance it will be necessary to remove End
Shell from Toaster. Make sure Thermostat is in "off" position, and Contacts (H)
are open, then with the Trip Lever up (no bread in Toaster) this clearance, as
indicated by dimension (D) ,should be approximately 1/16". Adjust by bending
Trip Lever. If this dimension is too small, then as Toaster heats up, it is
likely that Trigger (C) will not fall down, when toasted slice is removed, to
properly position it for next cycle. If, on the other hand, this dimension is
too great, there is apossibility that the Thermostat Blade (A) will not be
pushed forward sufficiently when next slice is inserted, causing the results
indicated in paragraph, Section D-3
(c) If the Bread Lifter Assembly (17) cannot be pushed down by hand, it is possible
that the end of the Trip Lever (E) Diagram I, got caught over the top of the
Trigger (C) .This might happen in shipping if the stops on the Side Frame
Assemblies (14 and 16) are bent out of position, allowing the Bread Lifter
Assembly to pass the stops. Bend stop lugs in correct position so that Bread
Lifter Assembly (17) cannot pass by when forced to one side or the other.
(d) The Reset Pin (G) might have come out of the hole in the Thermostat Bracket (F)
preventing the Contacts (H) from closing. This can be caused by the Trigger Arm
(K) being bent out of shape permitting the Pin (G) to pass by the Trigger Arm
(K), or the Contact Spring (H) might be improperly assembled causing
misalignment. Correct by bending Trigger Arm (K) in correct position or by
adjusting Contact Spring (H) .After this adjustment, care must be taken to make
sure there is aclearance of afew thousands (not over 1/64") between the Pin
and Trigger Arm when the Thermostat Blade is in the "off" position. To make sure
Thermostat is in the "off" position, push the Reset Arm (Diagram II) inward
below the pivot.
(e) Any electrical interruption will prevent the Bread Lifter Assembly from
lowering. Check all connections and cord.
3. Bread Moves Up and Down Continuously at Top of Slot -Dimension (D) (Diagram I), as
explained above, is too large. When this occurs, Thermostatic Blade (A) cannot be
moved forward sufficiently to snap it to its toasting position. However, the movement
is usually sufficient to close Contacts (H) .When this happens, the Bread Lifter
Assembly will begin to move down, but as soon as it moves about 1/2 inch, the Contact
Points (H) will open causing Bread Lifter Assembly to rise. This, in turn, will cause
Contact (H) to again close and thus repeat above cycle. Adjust

-12 -
Trip Lever (E) by bending so as to obtain approximately 1/16 inch clearance at
Dimension (D)
4.Toaster Operates Erratically (Successive Toasting Not Uniform )
(a) Thermostatic Blade may be rubbing against the aluminum-window reflector causing
friction and erratic operation. This can be readily checked by simply dropping
Bottom Cover Assembly and viewing from the bottom. If aportion of the reflector
appears to be sufficiently close to the Thermostatic Blade to cause rubbing, it
can be forced away with an ordinary screwdriver to permit proper clearance. The
two side edges of the window reflector should practically touch the
corresponding two sides of the opening provided for it in the reflector plate of
the end element.
(b) Minor adjustments can be made to correct inconsistent operation the Toaster, but
only in accordance with these instructions. If the Toaster fails to shut off,
remove Thermostat Assembly (12). Refer to Diagram I. With Contacts (H) in closed
position, check to see Pin (G) actually protrudes from Bracket (F) about 1/16
inch (Dimension B) .If Pin (G) does not protrude enough from Bracket (F), pres
on Spring at Contacts (H) until Pin is pushed forward so as to be 1/1 inch
distance out from inside surface of Bracket (F) (Dimension B) Make sure you have
contact clearance at Point (H) when Thermostat is in off position. If Pin (G)
protrudes too far out from Bracket (F) and approaches Blade (A), this may cause
inconsistent operation. To adjust, pry Mica Insulation (I) away from Bracket
(F) ,at point (J) ,with asmall screwdriver. This will move Contact Point
Assembly out causing Pin (G) to move away from Blade (A) .Pry open only enough
to allow 1/16 inch projection of Pin (G) (Dimension B)
(c) When Bread Lifter Assembly is all the way down, the inward protruding tongue on
the Bread Lifter Assembly should push down the Projecting Lever on the bottom of
the Trigger Lever Assembly (Diagram II) to make sure that the latter is all the
way out, and thus will not restrain the switch action. Occasionally, the Baffle
Plate, spot welded on the Bread Lifter assembly in the chamber marked "One
Slice", may be bent out of position, and touch the guide wires when Brea Lifter
Assembly is down. This will prevent the Bread Lifter Assembly from coming all
the way down, as explained above. To adjust, straighten Baffle Plate.
(d) If Toaster continues to operate erratically after all the above adjustments have
been made, check the Thermostat Blade. The Thermostat Blade should snap sharply
against the bracket when moved to the off position. If the blade has lost its
spring action then change the blade and stabilize as described in Section C5.

-13 -
5.Bread Rises Too Slowly
(a) This complaint may be due to the impatience of the user. Actually the toasting
cycle from acold start takes less time than any toaster previously
manufactured. The toasting cycle will vary with voltage changes, dryness of
bread, or if toaster is cold or warm. Under normal conditions (Which means
testing with moderately fresh bread on 115 Volts A.C. with Toaster set at
Medium) the total toasting cycle will vary from 1-1/2 minutes when starting with
acold Toaster to less than 1minute as the Toaster warms up. When properly
adjusted, it will lower or raise the bread in approximately 9seconds
(b) If Toaster is out of adjustment and takes 8to 12 seconds to raise the bread,
observe motion of Bread Lifter Assembly. The Bread Lifter Assembly should move
up and down smoothly without excessive jerking. Check to see that Bread Lifter
Assembly moves free of frame and adjust by bending, if necessary. If Bread
Lifter Assembly is free, then slightly turn the screw on the bottom of the
Center Element (10) counter-clockwise. This will increase the stress on the wire
of the Center Element causing its contraction to effect Bread Lifter Assembly
motion sooner. Do not make this adjustment unless absolutely necessary, and then
make only slight adjustment so as not to put to much stress on wire of Center
Element .Always test Toaster first under normal conditions ,to determine if
customer' scomplaint is justifiable and warrants an adjustment of this assembly.
6. Toast Not of Uniform Color -The individual elements are measured for resistance,
graded and matched at the factory, so as to obtain substantially uniform toasting on
all of the four faces comprising the two slices of bread in the Toaster at any one
time. It is clear that all four of these surfaces should be of uniform dryness. The
Center Element has associated with itself slightly more heat capacity than the end
elements, so that when Toaster is cold, the inside surfaces (those facing Center
Element) will come out slightly lighter than other two surfaces. However, with
perfectly matched elements and uniform condition of bread surface dryness, there
should be no great difference in color as Toaster heats up. Because of all the
variable factors, in addition to the two mentioned, do not assume that the elements
are mismatched unless several sets of toast are made and judgment passed on the
average result. If after such test, the inside surfaces consistently toast lighter
or darker than outside surfaces, replace with aset of matched elements, but only on
authorization by customer.
7. Single Slice Toasting -The two chambers are adequately baffled from each other so
as to permit toasting of asingle slice if desired. However if several single slices
are toasted in arow, the empty slot becomes so hot that it cannot but unavoidably
affect the other slot. As aresult, the bread surface facing the Center Element will
come out darker.
8. Outside Surfaces Have Dark Vertical Streaks -The end elements are wound

-14 -
into aspecial elliptical shape. It is essential, for uniform toasting of the full
area of the bread slice, that the long axis of this ellipse be at right angles to
the supporting reflector. If this condition does not exist, correct by twisting with
the fingers.
9.Toast is Lighter on Top
(a) If bread slices are abnormally tall, this will cause top to be lighter. In any
Toaster of conventional design, this will happen.
(b) If outside surfaces are light at the top, correct this condition by crowding the
turns of the end element coils toward the top and separating them at the bottom.
10. Toast Not Uniform in Color as Toaster Heats up .(Successive Slices Get Increasingly
Darker or Lighter)
(a) Proper compensation for Toaster temperature is inherent in the design and
manufacture of the Radiant Control Thermostatic Switch, and consequently
successive pairs of toast should be of the same color as the first pair with a
cold Toaster. If this uniformity does not exist, check possibility of faults as
outlined in Section D4
.
(b) If the above tests do not reveal anything, then it is likely that the Thermostat
Assembly is defective. In such acase, remove the Thermostat Assembly and
disassemble as described in section C-4 and replace the Thermostat Bracket
Assembly (12A)
.
11. Thermostat Does Not Shut Off Current
(a) Toaster might have been used on D. C. and the contact points are
melted. Replace Contact Points (12G and 12J) if they are damaged.
(b) Reset pin (G) might have fallen out due to reasons mentioned under. Paragraph
D2d. (See Diagram I)
(c) Thermostat might be rubbing against reflector, thus preventing it from shutting
off. Correct as per paragraph 4A.
12 .Bread Will Not Rise Even If Current Shuts Off .
Bread Lifter Assembly might be caught under the Projecting Lever (Diagram II) on the
bottom of the Trigger Lever Assembly. Bend the Projecting Lever in such aposition
that this cannot happen.
