Admiral Dryer Blowing Cold Air on Timed Dry:... | appliancefaults.com

Technical Background:

On timed dry, the timer circuit signals the motor to run and the heating element circuit to energize. The heating element, thermal fuse, and high-limit thermostat work together to generate heat safely. The centrifugal switch provides feedback to the motor control unit. A problem in any of these components or their control circuits can prevent the heating element from activating.

Symptoms:

The Admiral dryer is running, the drum is turning, and the timer is advancing on the timed dry setting, but the air coming out is cold or only slightly warm.

Possible Causes:

Failed heating element
Faulty thermal fuse
Defective high-limit thermostat
Malfunctioning centrifugal switch in the motor
Blocked dryer vent
Defective dryer timer or control board

Solution:

1

Disconnect power to the dryer at the breaker panel (LOTO).
2

Access the heating element housing (usually at the rear of the dryer) by removing the rear panel with a 1/4-inch nut driver.
3

Visually inspect the heating element for breaks or damage. Use a multimeter to test the heating element for continuity. A good element should have a resistance reading between 8-12 ohms.
4

Check the thermal fuse (typically located on the blower housing). Use a multimeter to test for continuity. A blown fuse will show no continuity.
5

Inspect the high-limit thermostat (also near the heating element). Test for continuity. It should show continuity at room temperature. Replace if open.
6

Verify proper venting. Disconnect the vent from the dryer and check airflow. If airflow is poor, clean the entire vent run.
7

Replace any failed components with manufacturer-approved parts.

Safety Warning:

Disconnect power to the dryer before performing any repairs. Dryers operate on 240V AC, which can cause serious injury or death. Always use proper safety precautions, including 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 to prevent lint buildup. Avoid overloading the dryer.

Expert Tip:

Sometimes a slightly loose connection at the heating element terminals can cause intermittent heating issues. After replacing the element, ensure the terminals are clean and tight. Use a small wire brush to clean corrosion off of the terminals before reattaching the wires.

Frequently Asked Questions

•What voltage should I expect to see at the heating element terminals when the dryer is running?

You should see approximately 240V AC at the heating element terminals when the dryer is running and the heating circuit is energized.

•How do I test the centrifugal switch in the motor?

Testing the centrifugal switch requires accessing the motor. With the dryer unplugged, use a multimeter to check for continuity across the switch terminals when the motor is at rest and again when the motor is manually spun. The switch should change state (open/close) when the motor spins.

•If the thermal fuse keeps blowing, what is the most likely cause?

A frequently blowing thermal fuse indicates a restriction in airflow or overheating. Check the vent for blockages, clean the blower wheel, and ensure the high-limit thermostat is functioning correctly.
