Door Interlock and Monitoring Switch
NOTE: When the line fuse is blown the Interlock Switch
Assembly must be replaced.
Interlock switch (assembly) mounts behind oven cavity
front bulkhead. It is actuated by door hook and guide
attached to the door.
Monitoring switch (contacts 7 and 8) is actuated by the
door guide.
The secondary interlock switch (contacts 2 and 3) and
primary interlock switch (contacts 4 and 5) are actuated
by the door hook.
The secondary interlock switch is in series with the
interlock monitoring switch in the monitor circuit.
If a malfunction occurs in the secondary interlock when
door opens, current will flow through the monitor switch
causing the oven fuse to open.
If a faulty door interlock switch has allowed current
through the monitor switch, the switch assembly must be
replaced (see interlock switch testing) before replacing
fuse.
DANGER
!
To avoid severe personal injury or death avoid
contacting any high voltage parts. The capacitors are
at high voltage (4000 volt) potential and it is extremely
important that they be grounded before handling.
Transformer High Voltage

supplieshigh voltage A.C. for operation of the magnetron
tube.
High Voltage Capacitor
Doublesthe A.C. output voltage from the high voltage
transformer.
High Voltage Diode (Rectifier)
Is connected at the output side of the high voltage
capacitor. It changes voltage from A.C. to D.C. It
passes current in one direction and blocks it in the other.
Also called a rectifier.
Magnetron
With filament voltage and high D.C. voltage from the
output of the H.V. capacitor, diode junction the
magnetron will put out an electomagnetic radio
frequency of 2450 MHz to heat the food load in the
oven.
Thermal Protectors
At a predetermined temperature the thermal cut-outs will
open or close. The oven will indicate an error code in the
display, initiate cooling fan operation, or prevent the
generation of microwave energy.
• Magnetron thermal cut-out is mounted directly on the
bodyof the magnetron.
• Oven cavity thermal cutout is mounted inside the
exhaust duct.
Touch Panels
Allows consumer operation and programming of oven.
Triacs
Triacs are controlled by high voltage circuit boards.

groundingprong from the plug or bend power prongs to fit
receptacleother than one shown for your equipment.
Such abuse of the plug can result in electrical shock or
overheating.
WARNING
!
Improper use of grounding plug can result in a risk of
electrical shock or death.
Thisequipment MUST be grounded. In the event of an
electrical short circuit, grounding reduces risk of electric
shock by providing an escape wire for electric current.
Thisoven is equipped with acord having grounding wire
with a grounding plug. Plug must be plugged into an
outlet thatis properlyinstalled and grounded. DO NOT
usea two-prong adapter.
Consulta qualified electrician or servicer if grounding
instructions are not completely understood or if doubt
exists as to whether the equipment is properly grounded.
Do not use an extension cord. If product power cord is
too short, have a qualified electrician install an
appropriatereceptacle. This equipment should be
plugged into a separate 60 Hz circuit with the appropriate
electrical rating label. When the oven is on a circuit with
other equipment, an increase in cooking times may be
requiredand fuses can be blown.
Unpacking Oven
• Inspect oven for damage such as dents in door or
insideoven cavity.
• Reportany dents or breakage to source of purchase
immediately.
•Do not attempt to use oven if damaged.
• Removeall materials fromoven interior.
• If oven has been stored in extremely cold area, wait a
fewhours beforeconnectingpower.
Radio Interference
Microwaveoperation may cause interference toradio,
televisionor a similar oven. Reduce or eliminate
interference by doing the following:
• Cleandoor and sealing surfaces of oven accordingto
instructions in Careand Cleaning section.
• Place radio, television, etc. as far as possible from
oven.
• Usea properly installed antenna on radio, television,
etc. to obtain stronger signal reception.
Oven Placement
• Do not install oven next to or above source of heat,
such as pizza oven or deep fat fryer. This could cause
microwaveoven to operateimproperly and could
shorten life of electrical parts.
• Do not block or obstruct oven filter.Allow access for
cleaning.
• Installoven on level countertop surface.
• Place warning label in a conspicuous place close to
microwaveoven.
• Outlet should be located so that plug is accessible
whenovenisin place.

Power Test (Traditional Test Method)
Test equipment required is Amana power test kit R0157397 (Fahrenheit), or
Menumaster power test kit M95D5 (Celsius).
1. Fill the plastic container to the 1000 ml. line with cool tap water.
2. Using the thermometer; stir the water, measure, and record the water temperature.
Initial water temperature should be approximately 60°F(16°C).
3. Place container on the center of the oven shelf and heat the water for
33 seconds for ovens with more than 1550 watts or 63 seconds for ovens with less than 1550 watts.
NOTE: Use a watch second hand, not the oven timer.
4. Stir the water, measure and record the temperature of the water after heating time is complete.
5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the
temperature rise (∆T).
6. See the Traditional Power Test Temperature Chart below.
NOTES: •The IEC-705 test method requires precision measurements and equipment. It is not practical to perform
the IEC test in the field. To convert the traditional power test results to the approximate IEC-705 rating,
take the traditional power test results and add 150 watts per magnetron for the unit being tested.
Example: 1400 watts output using the traditional power test for model RC17S
+ 300 watts (2 magnetrons X 150 watts)
1700 Approximate IEC-705 results
•Always perform power test three times for accuracy, changing the water after each test is performed.
•Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power
tests should be made if temperature rise appears marginal.
•Low line voltage will cause lower temperature rise.

WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
RS2240003 Rev. 0 20
CAUTION
!
All repairs as described in this troubleshooting section are to be performed only after the caution procedures one through
eight listed below have been followed.
1. Check grounding before checking for possible causes.
2. Be careful of the high voltage circuit.
3. Discharge high voltage capacitor.
4. When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from these parts
and then check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your
meter.
5. Do not touch any parts of the circuitry on the P.C. Board circuit since static electric discharge may damage this control
panel. Always touch yourself to ground while working on this panel to discharge any static charge in your body.
6. 208/230 VAC is present in the high voltage circuit board, power relay and primary circuit of low voltage transformer.
7. When troubleshooting, be cautious of possible electrical hazard.
8. When testing convection operation, convection fan may start at any time or if oven is hot.
Error Codes
During operation, the display may show the following service codes:
NOTE: Before scheduling service for any error codes, instruct customer to unplug oven for 1 minute,
reconnect power, and retest. If unit operates properly, no service call is required.
