MICROWAVE INFORMATION
DESCRIPTION AND FUNCTION OF COMPONENTS
The primary interlock switch is mounted in the lower position of the latch hook and the door sensing switch in the
secondary interlock system is mounted in the upper position of the latch hook. They are activated by the latch
heads on the door. When the door is opened, the switches interrupt the power to all high voltage components. A
cook cycle cannot take place until the door is firmly closed thereby activating both interlock switches. The
secondary interlock system consists of the door sensing switch and secondary interlock relay located on the
control circuit board.
The monitor switch is activated (the contacts opened) by the latch head on the door while the door is closed. The
switch is intended to render the oven inoperative, by means of blowing the C/T fuse, when the contacts of the
secondary interlock relay (RY2) and primary interlock switch fail to open when the door is opened.
Functions:
1. When the door is opened, the monitor switch contact close (to the ON condition) due to their being normally
closed. At this time the secondary interlock relay (RY2) and primary interlock switch are in the OFF condition
(contacts open) due to their being normally open contact switches.
2. As the door goes to a closed position, the monitor switch contacts are first opened and then the door sensing
switch and the primary interlock switch contacts close. (On opening the door, each of these switches operate
inversely.)
3. If the door is opened, and the secondary interlock relay (RY2) and primary interlock switch contacts fail to
open, the C/T fuse blows simultaneously with closing of the monitor switch contacts.
CAUTION: BEFORE REPLACING A BLOWN C/T FUSE TEST THE DOOR SENSING SWITCH, SECONDARY
INTERLOCK RELAY (RY2), RELAY (RY1), PRIMARY INTERLOCK SWITCH AND MONITOR SWITCH FOR PROPER
OPERATION. (REFER TO CHAPTER “TEST PROCEDURE”).
NOTE: C/T FUSE AND MONITOR SWITCH ARE REPLACED AS AN ASSEMBLY.

TURNTABLE MOTOR
The turntable motor rotates the turntable located on the bottom of the oven cavity, so that the foods on the
turntable cook evenly during cooking. The turntable may turn in either direction.
COOLING FAN MOTOR
The cooling fan motor drives a blade which draws external cool air. This cool air is directed through the air vanes
surrounding the magnetron and cools the magnetron. This air is channeled through the oven cavity to remove
steam and vapors given off from the heating foods. It is then exhausted through the exhausting air vents at the
oven cavity.
CAVITY TEMPERATURE FUSE
The cavity temperature fuse located on the top of the oven cavity, is designed to prevent damage to the oven by
fire. If the food load is overcooked, by either error in cook time or defect in the control unit, the cavity
temperature fuse will open. Under normal operation, the cavity temperature fuse remains closed. However, when
abnormally high temperatures are reached within the oven cavity, the cavity temperature fuse will open at
302OF(150OC) causing the oven to shut down. NOTE: This is fuse. It does not reset.

MICROWAVE INFORMATION
DESCRIPTION AND FUNCTION OF COMPONENTS
C/T TEMPERATURE FUSE
The C/T fuse located near the magnetron is designed to prevent damage to the magnetron if an over heated
condition develops in the tube due to cooling fan failure, obstructed air guide, dirty or blocked air intake, etc.
Under normal operation, the C/T fuse remains closed. However, when abnormally high temperatures are reached
within the magnetron, the C/T fuse will open at 302OF(150OC) causing the oven to shut down.
1. The C/T fuse blows when the contacts (COM-NO) of the secondary interlock relay (RY2) and primary interlock
switch remain closed with the oven door open and when the monitor switch closes.
2. If the wire harness or electrical components are shortcircuited, this monitor fuse blows to prevent an electric
shock or fire hazard.
NOTE: This is fuse. It does not reset.

T°
t (sec)
The convection oven uses the addition of a fan and an element to heat and to move the air already in the oven. Moving
the heated air helps to destratify the heat and cause uniform heat distribution. Cooking times can be reduced by as
much as 30%. The air is drawn in through a fan shroud and the element located on the rear wall of the oven. It is
then discharged around the outer edges of this shroud. The air circulates around the food and then enters the shroud
again. As with conventional electric ranges, there is still an oven vent which discharges through the bottom of the control
panel.
To set the control in convection mode, follow these steps:
1.Press the CONV. BAKE/ROAST pad.
2. Enter the desired temperature on the keypad (set point).
3. Press the START pad.
The oven will automatically start and the fan will begin to run. To cancel the convection baking/roasting function, press
the CANCEL pad.
NOTE:The fan runs continuously while in the convection mode. The fan and the convection element will stop if the
door is opened while convection baking/roasting. The bake element will continue to operate if the door is opened.
It is normal to see a temperature overshoot in the
first rise of all modes when you monitor the temperature.
FIRST RISE
When these modes are selected, the door locks right after start button is pushed.
CLEAN AND TIMED CLEAN
During a cleaning process, the oven uses bake and broil elements.
CLEAN
During a normal bake mode, the controller preheats the oven with the bake element. When the desired temperature
is reached, the controller adds top heat by cycling the broil element on for 12 to 18 seconds per minute. The bake
element is on for the remaining time of the minute. Both elements use full power when they are on but they are never
on at the same time.
NORMAL BAKE
During a preheat mode, the oven uses a bake element to reach the controller set point. The element uses full power
when it's on. When the set point is reached, the preheat mode is converted to a normal bake mode.

CONVECTION MODE
OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F/176°C. Obtain an average oven temperature after a
minimum of 5 cycles. Press Cancel to end bake mode.
Note: Changing calibration affects all the cooking modes but not the clean mode.

FAN BLADE
The fan blade is mounted in the rear of the unit and has a "D" shaped mounting hole. Only minimum clearance exists
between the oven back, fan blade, and fan shroud. Be careful not to bend blade when removing or installing.
Access to the fan blade is gained by removing the fan shroud, held in place by three screws, from the inside of the oven.
The fan blade is held in place with a hex nut that has left handed threads. When removing this nut, gently hold the
fan blade, and turn the nut clockwise. If one of the blades becomes deformed, it may be bent back into shape using
a flat surface as a reference.
A flat washer is located on the motor shaft between the snap ring on the shaft and the fan blade.
NOTE:If the fan blade is bent and motor vibrations increase, the noise made by the fan will be greater.
MOUNTING PLATE OVEN
The fan motor on the rear of the unit is mounted to the main back (with three screws). There is a mounting plate held
in place between the main back (with 2 screws) and the rear oven wall (with 2 screws). Should it be necessary to replace
the oven cavity, you must remove the 2 screws located inside the unit at the rear of the oven cavity.

DOOR LOCK MECHANISM
The appliance is equipped with an electronic oven control
and has an auto locking door latch feature. When the self
clean cycle is programmed, the door is locked by a motor
operated latch system. The interior of oven doesn't need to
heat up to 500°F/260°C before the door locks. However,
until the temperature inside oven reaches 500°F/260°C, the
self-clean program can be canceled and door will unlock
immediately. After oven reaches temperatures over 500°F/
260°C, the door will not unlock until temperature drops
below 500°F/260°C.
If a problem appears and the door stays locked it is
possible for the servicer to unlock the door without
removing the appliance from its place. Follow the steps
below:
1. Trip the circuit breaker to OFF position.
2. Remove the 2 screws, which are fixing the oven door
latch, located between the control panel and the oven
door.
3. When the screws are removed it is possible to unlock
the latch with a flat screwdriver, or one of the tools
supplied with the wall oven which are used to take off
the oven from the cabinet. Insert the tool tip through the
slot on top of the oven door. During this step it's
important to take care to not damage the appliance.
4. As soon as the latch is in the unlock position, you can
open the door.
FAN RELAY
The convection fan motor runs continuously while in the convection mode unless the door is opened. If the fan does
not operate, check the following:
• Display illuminated on the electronic control.
• Voltage output between terminals P5-7 and Neutral.
• 120 Volts available at fan motor.
• Fan motor coil resistance 15 ohms ± 10%.
• Door/light switch.
5. Replace the motor latch:
1. To have access to the door latch assembly, remove the 3 screws under the control panel which are fixing it.
2. Remove the access plate located on the upper air channel by removing the screw.
3. Replace the motor latch by a new one and reassemble in reverse order.
