The door is open and
HI. The door locking mechanism will be the culprit, here. In order to confirm the damage, you will need to gain access to the actual mechanism. Once you have exposed the locking mechanism, pay close attention to the actual circuit section of the mechanism. The contacts will be used for the testing procedure. You will need to inspect the wiring at the locking mechanism. make sure that it is connected to the main PCB, properly. One of the most common causes for this particular issue will be connection failure, due to a slight separation at the contacts. This separation can occur overtime. at the control board, or locking mechanism. Once the connection is severed, the locking mechanism will stall. The connections at the control and locking mechanism should be tight, with no corrosion, as well. Check the insulation around the wires for faults. If the connection to and from the control is optimal, this will lead to the actual door locking mechanism. Use the procedure below to test the circuit functionality.
DOOR LOCKING MECHANISM TEST:
Before repairs or further testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. Set the latch to the "clean" position and test for circuit continuity at the terminals of the switch with your VOM's ohmmeter function. If there is no continuity, the switch is faulty. Use caution when testing.
