[2] B: SWITCH TEST
CARRY OUT 3D CHECKS.
Isolate the switch to be tested and using an ohmmeter check between the terminals as described in the following table.

Open circuit
Depressed

If incorrect readings are obtained, make the necessary switch adjustment or replace the switch.
CARRY OUT 4R CHECKS.
[3] C: TEMPERATURE FUSE TEST
CARRY OUT 3D CHECKS.
Disconnect the leads from the terminals of the temperature fuse. Then using an ohmmeter, make a continuity test across the two terminals as
described in the below.
Parts Name
Temperature fuse 150 C
If incorrect readings are obtained, replace the temperature fuse.
An open circuit temperature fuse (OVEN) indicates that the foods in the oven may catch fire, this may be due to over heating produced by improper
setting of the cooking time or failure of the control panel.
CARRY OUT 4R CHECKS.
[4] D: MOTOR WINDING TEST
CARRY OUT 3D CHECKS.
Disconnect the leads from the motor. Using an ohmmeter, check the resistance between the two terminals as described in the table below.
Motors

Resistance
Approximately 384
If incorrect readings are obtained, replace the motor.
CARRY OUT 4R CHECKS.
[5] E: FUSE F10A
CARRY OUT 3D CHECKS.
1. If the fuse F10A is blown, there could be shorts or ground in electrical parts or wire harness.Check them and replace the defective parts or repair
the wire harness.
2. If the fuse F10A is blown when the door is opened, check the 1st. latch switch, 2nd. interlock relay and monitor switch.
If the fuse F10A is blown by incorrect door switching replace the defective switch(s) and the fuse F10A.
CARRY OUT 4R CHECKS.
CAUTION: ONLY REPLACE FUSE F10A WITH THE CORRECT VALUE REPLACEMENT.
