Admiral Dryer Lint Filter Housing Clogged: How to Access... | appliancefaults.com

Technical Background:

The dryer's MCU (Main Control Unit) monitors temperature and airflow. Restricted airflow due to a clogged lint housing causes the heating element to overheat. Safety thermostats then trip, interrupting the heating circuit. Poor airflow also increases drying time, as moisture cannot be efficiently removed from the drum.

Symptoms:

The homeowner observes that the Admiral dryer takes longer than usual to dry clothes. Clothes may be damp even after a full cycle. There might be a burning smell, or the dryer may shut off prematurely due to overheating. The lint filter is clean, but the problem persists.

Possible Causes:

Excessive lint buildup due to infrequent filter cleaning.
Dryer vent blockage restricting airflow.
Damaged lint filter allowing lint to bypass.
Improper dryer venting system (e.g., too many bends).
Small articles of clothing bypassing the filter and lodging deep inside.

Solution:

1

Disconnect the dryer from the power source at the breaker panel (120/240V AC). Test with a multimeter to confirm zero voltage.
2

Locate the lint filter housing. Remove the lint filter.
3

Use a shop vacuum with a narrow hose attachment to remove visible lint from the housing opening.
4

If the clog is deeper, you may need to remove the dryer's front panel. Consult the dryer's service manual for specific disassembly instructions. This usually involves removing screws along the top and bottom edges of the panel, using a 1/4-inch nut driver.
5

Once the front panel is removed, you should have better access to the blower housing and ductwork. Use the shop vacuum and a long, flexible brush (or specialized dryer lint removal kit) to clear the clog. Inspect the blower wheel for obstructions.
6

Reassemble the dryer, ensuring all connections are secure. Check the belt tension.
7

Test the dryer operation, verifying proper airflow and heating. Use an anemometer to measure airflow at the vent exhaust (should be at least 100 CFM).

Safety Warning:

Disconnect power to the dryer before performing any repairs. Verify zero voltage at the dryer receptacle using a multimeter. Wear gloves to protect your hands from sharp edges and debris. Follow Lock Out/Tag Out (LOTO) procedures.

Prevention:

Clean the lint filter after every load. Inspect and clean the dryer vent at least once a year. Use rigid metal ductwork for the vent, avoiding flexible plastic or foil ducts which can trap lint. Periodically check the outside vent cover for obstructions.

Expert Tip:

On some Admiral models, accessing the blower housing requires removing the drum. Before removing the drum, take a photo of the belt routing for easy reassembly. The drive belt tensioner usually requires a 1/2-inch wrench to relieve tension.

Frequently Asked Questions

•How often should I clean my dryer vent?

Ideally, you should clean your dryer vent at least once a year, or more frequently if you notice longer drying times or reduced airflow.

•What type of vent duct is best for my dryer?

Rigid metal ductwork is the best option for dryer vents. It provides smooth airflow and is less likely to trap lint compared to flexible plastic or foil ducts.

•How can I tell if my dryer is overheating?

Signs of dryer overheating include clothes that are still damp after a full cycle, a burning smell, the dryer shutting off prematurely, or the exterior of the dryer feeling excessively hot.
