Test Name Description Steps
TEST #9
Door Lock Motor
and Door Latch
Switch
Latch switch or motor
Examples:
1. F5E0
2. F5E1
3. F5E2
4. F5E3
NOTE: Run TEST #8 to ensure the
door switch function is functional
before this test.
1. Unplug range or disconnect power.
2. Remove door and toe panel to access main control.
3. Verify that ALL connectors are inserted all the way into the main control.
4. Connect AC voltmeter to P5-6 (L1 to Latch Motor) and P6-5 (N) for main cavity or between P5-7
(L1 to Latch Motor) and P6-5 (N) for left cavity latch motor.
5. Plug in range or reconnect power.
6. Close the door or press and hold the door switch. Move the knob to clean & clean positions,
press the start button. Wait and check if the door can be latched and monitor the AC voltage.
If the door is latched and the heater starts, the lock motor and latch switch functions are good.
Wait 3 minutes before checking if there is an error.
If there is no error, unplug range or disconnect power and go to step 12.
If the door latch motor does not operate or if there is no 120 voltage within 1 minute, unplug
range or disconnect power and go to step 7.
If the door latch motor operates but motor keeps operating after 1 minute, unplug range or
disconnect power and go to step 7.
7. If 120 VAC is not presented, check AC voltage between P5-9 (L1 input to relay) and P6-5 (N).
If 120 VAC is presented, the main control (ACU) is improperly functioning. Unplug range or
disconnect power, go to step 11.
8. Unplug range or disconnect power. Check continuity of P5-9 (L1) to L1 pin in power cord. Ensure
no wires are pinched or damaged.
If the wiring is damaged, replace main harness and go to step 12.
9. Check continuity of the latch motor and electrical connections between the main control ACU
P5-6 for main cavity or P5-7 for left cavity and motors. Ensure no wires are pinched or damaged.
If the wiring id is damaged, replace main harness or door latch harness and go to step 12.
10. Checking continuity of the latch switch and electrical connections between the main control
ACU P7-2, P7-6 and the main cavity door switch or between control ACU P7-4, P7-6 and the left
cavity door switch. Ensure no wires are pinched or damaged.
If the wiring is damaged, replace door latch switch harnesses or main harness and go to step12.
