Admiral Washer Sounds Like a Jet Engine During Spin... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) controls the drive motor speed and direction. The MCU sends a variable voltage signal to the motor control board, which then regulates the voltage supplied to the drive motor. The voltage path includes the motor windings, motor capacitor, and associated wiring harnesses. A voltage imbalance or excessive vibration can indicate a problem with the motor or its associated components.

Symptoms:

The Admiral washer makes a loud, high-pitched noise, described as sounding like a jet engine, specifically during the spin cycle. The noise is significantly louder than normal operation.

Possible Causes:

Worn or damaged tub bearings.
Foreign object lodged between the spin basket and the outer tub.
Worn or damaged motor coupling.
Defective drive motor.
Worn or loose pulley system.

Solution:

1

Disconnect the washer from the 120V AC power supply. Use Lock-Out-Tag-Out (LOTO) procedures.
2

Remove the top panel of the washer. Usually involves removing screws at the rear of the machine with a 1/4-inch nut driver.
3

Inspect the tub bearings. Check for play in the inner tub while the outer tub is stationary.
4

Check for any visible obstructions between the spin basket and the outer tub. Remove the spin basket for thorough inspection, often requiring a 7/16-inch socket.
5

Examine the motor coupling for signs of wear or damage. Replace if necessary.
6

Inspect the drive motor and pulley system. Check belt tension and pulley alignment. Use a multimeter to test the motor windings for continuity.
7

Reassemble the washer and test the spin cycle.

Safety Warning:

Always disconnect power before servicing. High voltage components are present. Use LOTO procedures to prevent accidental energization. Wear appropriate safety gear.

Prevention:

Regularly inspect and clean the washer, paying attention to potential obstructions. Avoid overloading the machine. Use appropriate detergent amounts.

Expert Tip:

On some Admiral models, you can enter a diagnostic mode by pressing and holding the Start/Pause button for 5 seconds while simultaneously pressing the Water Level button three times. This can reveal error codes that further pinpoint the issue.

Frequently Asked Questions

•What is the resistance I should expect when testing the motor windings?

The resistance values will vary depending on the motor, but typically you'll see a few ohms between each winding and very high resistance (megohms) to ground.

•How do I remove the inner wash basket?

Typically, there is a bolt or nut at the bottom center of the wash basket. After removing the bolt, you may need a basket removal tool to pull the basket free from the drive shaft.

•Where can I find replacement parts for my Admiral washer?

You can typically find replacement parts online at appliance parts retailers or through authorized Admiral service centers.
