Amana Washer Lid Lock Clicking 3 Times and Stopping:... | appliancefaults.com

Technical Background:

The main control unit (MCU) sends a 120V AC signal to the lid lock solenoid. This solenoid then actuates a locking mechanism that prevents the lid from being opened during the wash cycle. The MCU monitors the lock switch to confirm engagement. If the MCU doesn't see the expected feedback, it may try a few times (hence the clicks) and then give up.

Symptoms:

The homeowner observes that the Amana washing machine lid lock attempts to engage, clicking three times, but then fails and stops. The washer will likely not start the wash cycle.

Possible Causes:

Faulty lid lock switch assembly
Obstruction preventing lid lock from engaging
Wiring harness issue between the MCU and lid lock
Failed or failing main control unit (MCU)
Incorrect lid alignment
Loose connection at the lid lock or MCU

Solution:

1

Unplug the washer from the outlet to prevent electrical shock. Use proper Lock Out Tag Out (LOTO) procedures.
2

Inspect the lid lock mechanism for any visible obstructions or damage. Remove any debris.
3

Check the wiring harness connecting the lid lock to the main control unit (MCU) for continuity. Use a multimeter to test for broken wires or loose connections.
4

Use a multimeter to test the voltage at the lid lock connector while the washer is attempting to lock. You should see approximately 120V AC.
5

If voltage is present, replace the lid lock switch assembly.
6

If no voltage is present, inspect the main control unit (MCU) for damage. If damaged, consider replacing the MCU.
7

After replacing any parts, run a diagnostic cycle to verify the repair. Consult the tech sheet for the service mode sequence.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. High voltage is present in the appliance, and improper handling can result in serious injury or death. Use Lock Out Tag Out (LOTO) procedures to ensure the appliance remains de-energized during the repair.

Prevention:

Avoid slamming the lid. Regularly inspect the lid lock area for debris. Periodically check the wiring harness for wear and tear.

Expert Tip:

Many Amana washers have a service mode that can be accessed by pressing a specific sequence of buttons (usually the start and cycle select buttons). Entering service mode allows you to run diagnostic tests and view error codes directly, sometimes bypassing the need to interpret the clicking alone.

Frequently Asked Questions

•What is the correct part number for the lid lock assembly on this washer if I don't know the model number?

Without the specific model number, you can often find the correct part number by searching online parts retailers using the washer's general type (e.g., 'Amana top load washer lid lock') and visually matching the component. Also, check the Amana website by entering a general description.

•How do I access the main control unit (MCU) on this Amana washer?

Typically, the MCU is located behind the control panel. You will need to remove the screws securing the control panel to the washer cabinet. Be careful when disconnecting the wiring harnesses from the MCU to avoid damaging the connectors. A 1/4-inch nut driver will usually suffice.

•What resistance should I expect to see across the lid lock switch when it is in the locked position?

When the lid lock is engaged and the switch is closed, you should see a very low resistance, close to 0 ohms, indicating a closed circuit. If the resistance is high (over 1 ohm), the switch may be faulty.
