Admiral Washer Agitates But Won't Spin: Troubleshooting... | appliancefaults.com

Technical Background:

The washer's Motor Control Unit (MCU) controls all functions, including spin. The MCU relies on sensor inputs, like the lid switch, to enable the spin cycle. When the lid is open, the lid switch should break the circuit, preventing spinning. The MCU sends 120V AC to the motor via relays and also controls the drain pump.

Symptoms:

The Admiral washer fills, agitates normally during the wash cycle, and drains. However, it fails to spin, leaving the clothes soaking wet, especially towels. The motor might hum or do nothing at all during the spin cycle.

Possible Causes:

Worn or broken drive belt
Faulty lid switch
Failed motor or motor capacitor
Defective drain pump or blockage
Problematic control board (MCU)

Solution:

1

Unplug the washer from the 120V AC outlet. Always disconnect power before working on appliances.
2

Inspect the drive belt. If it's loose, cracked, or broken, replace it. A worn belt can slip, preventing the tub from spinning.
3

Test the lid switch for continuity using a multimeter. It should show continuity when the lid is closed and no continuity when open. A faulty switch prevents the spin cycle.
4

Check the motor capacitor (if equipped). A bulging or leaking capacitor needs replacing. Use a 1/4-inch nut driver to access.
5

Verify the drain pump is working and there are no obstructions in the drain hose. The washer won't spin if it can't drain.
6

Access the control board (MCU) and check for any burnt components or loose connections. Consider replacing the MCU if other components are fine.
7

Test motor windings with multimeter for shorts to ground.

Safety Warning:

Disconnect power before servicing. Lock-out/Tag-out (LOTO) procedures must be followed to prevent accidental energization. High voltage components are present; exercise caution.

Prevention:

Avoid overloading the washer, which strains the motor and belt. Regularly clean the lint filter and check the drain hose for clogs.

Expert Tip:

Many Admiral washers have a service mode. To access it, simultaneously press and hold the Start/Pause and Cycle Select buttons for 3 seconds. This allows you to run diagnostic tests, including a spin test, to pinpoint the problem.

Frequently Asked Questions

•What is the correct drive belt size for my Admiral washer?

Refer to the model number located on the appliance. This allows the correct belt length and width to be identified

•How do I test the motor capacitor?

Disconnect the capacitor from the circuit and use a multimeter set to capacitance mode to measure its microfarad (uF) rating. Compare the reading to the capacitor's printed value. A significant deviation indicates a faulty capacitor.

•How can I tell if my MCU is defective if there are no visible signs of damage?

If all other components (lid switch, motor, pump, etc.) test good, and the washer still won't spin, the MCU is likely the culprit. However, replacing the MCU should be a last resort. Ensure to check all wiring harnesses and connections before replacing control board.
