Admiral Dryer Loud Grinding Noise: Troubleshooting Guide... | appliancefaults.com

Technical Background:

Most Admiral dryers use an MCU (Microcontroller Unit) to control the motor, heating element, and other components. The motor circuit typically uses a relay controlled by the MCU. Voltage paths include 120V AC for the motor control and 240V AC for the heating element (depending on model).

Symptoms:

The homeowner reports a loud, metal on metal grinding noise emanating from the Admiral dryer during operation. The noise may be intermittent or constant, and it may be louder during certain parts of the drying cycle.

Possible Causes:

Worn drum support rollers
Damaged drum glides/slides
Worn or broken blower wheel
Failed motor bearings
Debris lodged between the drum and cabinet

Solution:

1

Disconnect power to the dryer at the breaker panel. Verify 0V AC at the dryer receptacle using a multimeter.
2

Remove the lint filter and the front panel of the dryer (typically using a 1/4-inch nut driver).
3

Inspect the drum support rollers for wear, flat spots, or damage. Replace if necessary. These are typically held in place by a retaining clip or screw and can be removed with a 5/16-inch socket.
4

Examine the drum glides/slides (usually located at the front of the dryer drum) for wear or breakage. Replace in pairs. They often snap into place.
5

Check the blower wheel for cracks or obstructions. Remove any debris and replace the wheel if damaged. The blower wheel is commonly secured with a nut or screw.
6

Manually rotate the dryer drum. Listen carefully for any grinding noise. If the noise persists, suspect the motor bearings.
7

If the motor bearings are suspected, consult a qualified technician for motor replacement or repair. Replacing the motor involves disconnecting wiring, removing the drive belt, and unbolting the motor from its mount.

Safety Warning:

Disconnect power to the dryer before performing any repairs. Lock Out/Tag Out (LOTO) the breaker panel to prevent accidental re-energizing of the circuit. Dryer circuits often carry 240V AC, which can be lethal.

Prevention:

Regularly clean the lint filter after each load. Periodically inspect the drum support rollers and glides for wear and tear. Avoid overloading the dryer with excessive amounts of laundry.

Expert Tip:

Some Admiral dryers have a diagnostic mode that can display error codes or provide component testing features. Refer to the service manual for instructions on accessing the diagnostic mode. This can help pinpoint the source of the noise. Sometimes this involves pressing a combination of buttons simultaneously.

Frequently Asked Questions

•How do I access the service mode on my Admiral dryer?

Accessing service mode typically involves a specific button sequence, often involving pressing and holding the start button and another button simultaneously for a few seconds. Refer to the service manual for the exact sequence for your specific model.

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

You can find replacement parts at most appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your dryer's model number handy to ensure you get the correct parts. Sites like AppliancePartsPros.com or RepairClinic.com are good options.

•How do I know if the noise is coming from the front or the back of the dryer?

Carefully listen while the dryer is running (if safe to do so). If the noise seems to be coming from the front, focus your attention on the drum glides/slides and front drum support rollers. If the noise is coming from the back, inspect the rear drum support rollers and motor bearings.
