Whirlpool ghw9100 Door lock solenoid 60 ohm and 126 ohm? Duet job aid says 60 ohms on contact point 3 to 2 and 3 to 1 that is not possible because the two windings double the resistance the way its made. ...
The terminal numbering of the door lock and unlock solenoids solenoid looks messed up and your resistance reading is correct and the solenoids are good as long as you get 60 ohms both on 3-2 and 2-1 and 120 ohms on 3-1.
You stated, as per live chat discussion, that the door never locks to start a cycle. The door locking routine starts only if the door switch contact is closed (refer to page 6-2 of Job Aid L-68). This could mean the door switch contact never closes for the door locking routine to be initiated and a wash cycle can start or the CCU is not detecting it closed.
Check the continuity of the door lock and switch assembly wire harness (door switch, door lock main switches, and solenoids wire harnesses) including the connectors. Replace the wire harness if a discontinuity or any other issue that might jeopardize its function is found. Proceed with the troubleshooting if no issue is found with the harness or if the problem is not resolved with the replacement of the harness.
Reinstall the door lock and switch assembly, reconnect the wires, put the door gasket back over the outer lip of the door opening, and close the door. Reconnect the door lock main switches and the door lock/unlock solenoids harness except the door switch harness. Jump a wire between the door switches terminal connections (adjacent terminals) on the central control unit (CCU) then reconnect power and start the machine.
The door locking routine should start and eventually lock the door and start the cycle if the issue is with the door switch not closing. Replace the door lock and switch assembly if that is the case. The problem is in the CCU not detecting the door switch closing and needs to be replaced if door locking routine still fails to start, lock the door, and start the cycle.
If the door locking routine starts and the door lock seems engaging but fault code "FdL" flashes and the door is locked, unplug the machine then check the continuity of the door lock main switches at the wire harness connector in the CCU (refer to page 5-3 of Job Aid L-68). The problem is also with the door lock and switch assembly if there's no continuity in any of the door lock main switches. Otherwise, the problem is in the CCU not detecting door lock main switches closing and needs to be replaced if there's continuity in the switches.
With the fault "FdU" flashing when the door lock main switches bypassed, the CCU is certainly detecting the switches closed. This eliminates the possibility of the CCU not detecting the door lock main switches closing. It leaves only the possibility that the door switch is not closing or the CCU is not detecting it closing.
