TEST PROCEDURE
OR CORRECTION
1. High voltage transformer.
Little or no heat is produced
in the oven load.
1. Check the high voltage
transformer.
2. Check the high voltage
rectifier diode.
3. Check the high voltage
capacitor.
4. Check the magnetron.
5. Check the power selec-
tor.
1. Primary interlock switch. 1. Check primary interlock
switch.
2. Repair wiring.
Oven fuse blows when the
door is opened.
Oven lamp goes on with the
door open, but the light goes
out when the door is closed
with the control on.
1. Secondary interlock. 1. Check secondary inter-
lock.
The power source fuse blows
when the door starts to open.
1. High voltage trans-
former.
2. Secondary circuit of the
high voltage transformer
is shorted.
3. High voltage capacitor is
shorted.
4. Shorted wiring between
the above components.
1. Check the high voltage
transformer.
2. Check the high voltage
transformer.
PROBLEM
POSSIBLE CAUSE
3. Check the high voltage
capacitor.
4. Use an ohmmeter to
check continuity, and
repair wiring.
5. Check blower motor.5. Blower motor.
1. Fan motor.
2. Open or loose wiring in
circuit to fan motor.
Fan motor will not operate. 1. Check fan motor.
2. Use ohmmeter to check
continuity, and repair
wiring.
2. Shorted wire harness.
2. Rectifier diode.
3. High voltage capacitor.
4. Magnetron.
5. Power selector.
