Speed Queen Dryer Squealing Noise: Troubleshooting and... | appliancefaults.com

Technical Background:

Speed Queen dryers utilize a motor to rotate the drum via a belt and idler pulley system. The drum is supported by rollers. The motor also drives a blower wheel to circulate air for drying. A squealing noise usually indicates friction between moving parts due to wear, lack of lubrication, or obstructions.

Symptoms:

The homeowner reports a squealing or high-pitched noise emanating from the Speed Queen dryer during operation. The noise may be constant or intermittent and may increase with drum speed.

Possible Causes:

Worn drum support rollers.
Worn or unlubricated idler pulley.
Worn blower wheel or blower housing rubbing.
Worn motor bearings.
Debris caught between the drum and rear panel.

Solution:

1

Unplug the dryer from the outlet.
2

Remove the front panel of the dryer using a 1/4-inch nut driver.
3

Inspect the drum support rollers for wear or damage. Replace if necessary.
4

Inspect the idler pulley for wear or damage. Check for proper lubrication. Apply high-temperature grease if needed or replace the pulley.
5

Check the blower wheel and blower housing for obstructions or rubbing. Remove any debris.
6

If the noise persists, the motor bearings may be failing. A qualified technician should replace the motor.
7

Check between the dryer drum and rear panel for debris, remove if necessary.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. Always verify the unit is de-energized with a multimeter. Be aware that capacitors may store a charge even after the power is disconnected. Work carefully and wear appropriate personal protective equipment.

Prevention:

Regularly clean the lint filter after each use. Annually, inspect and lubricate the idler pulley with high-temperature grease. Check and clean the blower housing for lint buildup. Consider replacing the drum support rollers every 5 years as preventative maintenance.

Expert Tip:

A common cause of squealing is the idler pulley bearing. You can sometimes temporarily quiet the noise by applying a small amount of high-temperature grease to the bearing, but replacement is the best long-term solution. To access service mode on some Speed Queen models, press and hold the Cycle Selector knob while simultaneously pressing the Start button three times within five seconds. Consult the service manual for your specific model.

Frequently Asked Questions

•What type of grease should I use to lubricate the idler pulley?

Use a high-temperature grease specifically designed for appliance applications. White lithium grease is often a good choice.

•How do I remove the blower wheel from the motor shaft?

The blower wheel is typically held in place with a retaining clip or screw. Remove the clip or screw and then carefully pull the blower wheel off the motor shaft. You may need to use a gear puller if it is stuck.

•Where can I purchase replacement parts for my Speed Queen dryer?

You can purchase replacement parts from authorized Speed Queen dealers, online appliance parts retailers, or local appliance repair shops.
