TEST #8 Door Lid Lock
Perform the following checks if washer fails to lock (or unlock).
1. Perform Manual: Door Switch and Manual: Door Lid Lock tests.
2. Remove the console to access the machine/ motor control assembly. See Accessing & Removing the Electronic Assemblies.
3. Visually check that the P12 connector is inserted all the way into the machine/motor control. If visual check passes, go to step 4. If visual check fails, reconnect P4 and repeat step 1.
4. Check the lid lock motor winding and switches by removing P12 from the machine/ motor control and checking the
resistance values....



Component/Resistance Unlocked/Resistance Locked/Contacts Measured/Contacts Measured:


Motor Winding/35 ±5 O/35 ±5 O/P12-2/P12-3/
Lock Switch - Home/0 O/Open Circuit/P12-1/P12-4
Lock Switch - Lock/Open Circuit/0 O/P12-1/P12-7
Lock Switch - Lid/Lid Closed = 0 OLid Open = Open Circuit/Lid Closed = 0 O Lid Open = Open Circuit/P12-1/P12-5




If resistance values are good, go to step 5. If switch measurements do not match the values shown in the table for unlocked (or locked) conditions, a problem
exists in the door lid lock. Replace the door lid lock.
5. If the Manual: Door Switch or Manual: Door Lid Lock in step 1 failed, then the machine/motor control has failed: Unplug washer or disconnect power.
Replace machine/motor control assembly. Perform the Manual: Door Switch and Manual: Door Lid Lock in step 1 to verify repair.
