Speed Queen Dryer Burning Smell on High Heat:... | appliancefaults.com

Technical Background:

The Speed Queen dryer utilizes a heating element controlled by thermostats and a timer or electronic control board (MCU). When high heat is selected, the MCU energizes the heating element circuit. Safety components like the high-limit thermostat are in place to prevent overheating. Voltage is supplied from the breaker panel, typically 240V AC, to the dryer.

Symptoms:

The homeowner notices a distinct burning smell emanating from the dryer, particularly when operating on the high heat setting. Clothes may also feel excessively hot or have a slight scorched odor.

Possible Causes:

Lint build-up in the lint trap, ductwork, or blower housing.
Overheated heating element due to restricted airflow.
Failed or failing high-limit thermostat.
Worn or damaged drum glides/seals creating friction.
Foreign objects (e.g., plastic, rubber) caught in the drum or heating element area.

Solution:

1

Unplug the dryer from the outlet and turn off the breaker.
2

Thoroughly clean the lint trap and exhaust ductwork. Use a dryer vent cleaning kit to remove any blockages.
3

Inspect the heating element for signs of damage, such as breaks or hot spots. Check for continuity with a multimeter; it should read approximately 9-11 ohms.
4

Test the high-limit thermostat with a multimeter. It should have continuity when the dryer is cold. Replace if open or showing signs of damage.
5

Examine the drum glides and seals for wear or damage. Replace if necessary. These components are often made of felt or nylon and can wear down over time, causing friction.
6

Check the blower wheel for obstructions. Remove any lint or debris that may be restricting airflow.
7

Reassemble the dryer and test on the high heat setting, monitoring for the burning smell. Verify voltage at the heating element is approximately 240V AC when operating.

Safety Warning:

Disconnect power before servicing. Lock Out/Tag Out (LOTO) procedures must be followed. High voltage is present during operation – exercise extreme caution.

Prevention:

Clean the lint trap after every load. Inspect and clean the exhaust ductwork at least once a year. Ensure proper dryer venting to the outside. Avoid overloading the dryer.

Expert Tip:

Many Speed Queen dryers have a service mode accessible by pressing and holding specific buttons simultaneously. Consult the service manual for your specific model to access diagnostic codes and run self-tests.

Frequently Asked Questions

•What is the typical lifespan of a Speed Queen dryer heating element?

A Speed Queen dryer heating element typically lasts between 5 to 10 years, depending on usage frequency and maintenance.

•How do I properly clean the blower housing on my Speed Queen dryer?

Disconnect power and remove the front panel. The blower housing is typically located at the bottom of the dryer. Use a vacuum cleaner with a hose attachment to remove lint and debris. A small brush can help dislodge stubborn build-up.

•What type of lubricant is recommended for the drum support rollers on a Speed Queen dryer?

A high-temperature, silicone-based grease is recommended for lubricating drum support rollers. Apply sparingly to the roller axles.
