Speed Queen Dryer: Lint Build-Up Inside Drum -... | appliancefaults.com

Technical Background:

While Speed Queen dryers are relatively simple, airflow is critical. The centrifugal blower forces heated air through the drum. Restricted airflow causes lint to recirculate and deposit within the drum, instead of exiting through the vent. The MCU monitors thermistor temperatures and cycle times; extreme cases can trigger thermal fuse failure.

Symptoms:

US homeowner observations include finding excessive amounts of lint inside the dryer drum, clothes taking longer to dry, and potentially a burning smell.

Possible Causes:

Blocked lint filter or filter housing.
Damaged or improperly installed lint filter.
Restricted exhaust vent.
Air leaks in the dryer ductwork.
Improper dryer venting material (e.g., flexible plastic).
Clogged blower wheel.

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 clean the filter housing with a vacuum and brush. Check for any obstructions.
3

Inspect the lint filter for damage (tears, holes). Replace if necessary.
4

Disconnect the exhaust vent from the dryer and the wall. Inspect for lint buildup and obstructions. Clean the vent using a dryer vent cleaning brush kit.
5

Check the dryer blower wheel for lint accumulation. Access the blower housing by removing the dryer's front panel (requires a 1/4-inch nut driver). Clean the blower wheel with a brush and vacuum.
6

Inspect the dryer ductwork for air leaks. Seal any leaks with foil tape.
7

Ensure the dryer vent is made of rigid metal ducting, not flexible plastic. Replace if necessary.

Safety Warning:

Always disconnect power to the dryer before performing any maintenance or repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Dryer circuits are typically 240V AC and can be lethal. Use extreme caution when working with electrical components.

Prevention:

Clean the lint filter after every load. Inspect and clean the exhaust vent at least once a year, or more frequently if you dry large loads or have pets.

Expert Tip:

Some Speed Queen models have a service mode for testing components. To enter service mode, simultaneously press and hold the Cycle Selector and Start buttons for 5 seconds. Diagnostic codes can then be read from the display. (Note: refer to the tech sheet for your specific model for the correct sequence).

Frequently Asked Questions

•How do I access the blower wheel on my Speed Queen dryer?

Typically, you'll need to disconnect power, then remove the front panel of the dryer. This usually involves removing screws along the top and bottom edges of the panel. Once the front panel is removed, you should have access to the blower housing. Refer to your dryer's service manual for specific instructions.

•What type of ducting is recommended for a dryer vent?

Rigid metal ducting is the safest and most efficient option. Avoid using flexible plastic or foil ducting, as these materials can easily trap lint and are a fire hazard. Use 4-inch diameter ducting for optimal airflow.

•My dryer vent is clear, but I still have lint buildup. What else could it be?

Check for air leaks in the dryer ductwork. Even small leaks can reduce airflow and cause lint to deposit inside the drum. Also, ensure the lint filter is properly seated and not damaged. An improperly installed or damaged filter will allow lint to bypass the filter and enter the dryer.
