Admiral Washer Lid Lock Light Flashing: Troubleshooting... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) sends a 120V AC signal to the lid lock assembly. When the lid is closed, the lid lock switch engages, signaling back to the MCU that it is safe to start the wash cycle. A flashing lid lock light indicates an error in this communication or a failure of the locking mechanism itself. Voltage paths include the main power supply, wiring harness, lid lock switch, and back to the MCU.

Symptoms:

The Admiral washer's lid lock light is flashing, and the machine will not start a wash cycle. The user may hear a clicking sound, but the lid remains unlocked.

Possible Causes:

Faulty lid lock switch
Obstruction preventing lid lock engagement
Damaged wiring harness to the lid lock
Failed main control board (MCU)
Defective door strike
Imbalanced load condition

Solution:

1

Unplug the washer from the outlet.
2

Visually inspect the lid lock assembly for any signs of damage or obstruction.
3

Using a multimeter, check the voltage at the lid lock connector. You should see approximately 120V AC when the washer is attempting to lock the lid.
4

Disconnect the wiring harness from the lid lock. Use a multimeter to test the continuity of the lid lock switch in both the locked and unlocked positions. Replace if faulty.
5

Inspect the wiring harness for any frayed or broken wires. Repair or replace as needed.
6

If the wiring and lid lock switch are good, the main control board (MCU) may be faulty. Replacement of the MCU is recommended.
7

After repairs, plug the washer back in and test its operation.

Safety Warning:

Disconnect power to the appliance before attempting any repairs. High voltage is present. Follow Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energizing of the appliance.

Prevention:

Avoid overloading the washer. Regularly check for and remove any obstructions around the lid lock area. Use appropriate HE detergent.

Expert Tip:

Some Admiral washers have a service mode. Entering this mode allows you to run diagnostic tests on the lid lock and other components. Consult the service manual or manufacturer's website for the specific sequence for your model. Typically you press and hold START/PAUSE for 3 seconds, then rapidly press POWER, START/PAUSE, POWER, START/PAUSE within 6 seconds. Then try to initiate a lid lock diagnostic function in the service menu.

Frequently Asked Questions

•How do I access the lid lock assembly?

Typically, you'll need to remove the top panel of the washer. This usually involves removing screws at the rear of the machine. Once the top panel is removed, the lid lock assembly should be accessible.

•What type of multimeter should I use?

A standard digital multimeter (DMM) capable of measuring AC and DC voltage, resistance (ohms), and continuity is suitable. Make sure it is UL listed for safety.

•How do I identify the correct replacement lid lock switch for my model?

Locate the model number of your washer (usually on a sticker inside the door or on the rear panel). Use this model number to search for compatible replacement parts on appliance parts websites or consult with a local appliance parts dealer.
