The oven door consists of door panel, front screen,
door frame, choke cover, inner screen, latch, spring
and choke cover cap.

1. Disconnect power and remove glass turntable from

oven.

2. Remove choke cover very carefully with a flat-blade

screwdriver.

3. Lift door up until pins clear holes of hinges.

1. Insert flat type small screwdriver into the gap between

choke cover and lower right corner of the door frame
first and then around the seal plate to free engaging
parts of choke cover.

2. The latch can be removed by lifting up the latch until

pins clear mounting holes.

3. Disconnect spring.

1. Discharge capacitor.
2. Disconnect magnetron leads.
3. Remove 4 screws securing the magnetron.
4. Removed the magnetron assembly until the tube is

clear from the waveguide.

1. Discharge capacitor.
2. Disconnect the leadwire from the high voltage capacitor.
3. Remove the screw holding the high voltage capacitor

bracket.

1. Disconnect power and remove glass tray from cavity.
2. Turn oven upside down and cut the motor cover tabs.
3. Bend corner areas flat where corners have been

snipped off. No sharp edges must be evident after
removal of turntable cover.

4. Disconnect wires from motor and remove 2 screws

securing motor to oven cavity.

5. Mount motor in reverse order.

1. Disconnect power. Discharge capacitor.
2. Remove one(1) screw mounting control.
3. Lift up control assembly to disengage hooks from

front frame.

4. Disconnect leads from PCB.

1. Remove control panel assembly.
2. Disconnect ribbon cable.
3. Remove 2 screws securing PCB. 

Key Panel and Control Panel will be replaced as one
assembly.

If necessary the key panel pads can be verified by a
continuity test.
For ease of handling, the key panel 
should be removed and placed on 
a flat surface.
Check continuity between connections
at the end of ribbon.(Use high 

Ω

scale.)

1. Disconnect sensor connector from PCB.
2. Measure resistance terminal to terminal.

(ohm meter scale : R 

X

1000)

Normal : Approximately
BLK-RED : 6.2 Kohm
RED-WHT : 3.1Kohm
BLK-WHT : 3.1 Kohm

* Sensor cooking conditions
1. Oven should be plugged in at least 5 minutes.
2. Room temperature should not exceed 95˚F.
3. Be sure the exterior of the cooking container

and the interior of the oven are dry.

• Set Clock-Touch clock pad,enter time of day and touch

clock again.

• Alternately touch each function pad and enter time

selection for the function-also change power levels.

• Touch Stop/Clear after each function test to clear that

function.

• Repeat procedure for each function to exercise each

pad.

• Control and display should respond to each entry.
• Display should revert to Time-Of-Day in the Clear mode.

An oven temp sensor mounted on the upper side of
oven cavity. its purpose is to automatically shut off the
oven in case the cavity overheats for any reason. 
When replacing be sure to determine cause of failure.
The failure sensor opens at 194˚F(90˚C) and is non-
resetable.

The touch control uses a low voltage transformer locat-
ed on printed circuit board.

TO PREVENT ELECTRICAL SHOCK, USE EXTREME
CAUTION WHEN DIAGNOSING OVEN WITH OUTER
CASE REMOVED AND POWER "ON". THE HIGH
VOLTAGE SECTION OF THE POWER SUPPLY,
INCLUDING FILAMENT LEADS IS - 4000 VOLTS
POTENTIAL WITH RESPECT TO GROUND.
