Admiral Dryer Not Heating: Troubleshooting Guide - Solar... | appliancefaults.com

Technical Background:

The dryer's MCU (Microcontroller Unit) controls the heating circuit based on sensor inputs (temperature, moisture). Voltage (240V AC in US) is supplied to the heating element through safety components like the thermal fuse and high-limit thermostat. The centrifugal switch ensures the heating element only activates when the motor is running.

Symptoms:

The Admiral dryer drum is turning, but no heat is being produced. Clothes remain damp even after a full drying cycle.

Possible Causes:

Blown thermal fuse
Faulty heating element
Defective high-limit thermostat
Malfunctioning centrifugal switch
Broken or loose wiring to heating components

Solution:

1

Unplug the dryer from the 240V outlet and disconnect the gas supply (if applicable). Use a 1/4-inch nut driver to remove the rear access panel.
2

Locate the thermal fuse on the blower housing. Test for continuity using a multimeter. A reading of OL (open loop) indicates a blown fuse; replace it with an exact match.
3

Access the heating element housing. Disconnect the wires and test the element for continuity. An open reading means the element is burnt out; replace it.
4

Inspect the high-limit thermostat near the heating element. Test for continuity. Replace if it's open.
5

Check the centrifugal switch inside the motor. It should be closed when the motor is off. Use a multimeter to verify. Clean any lint or debris that may be preventing it from closing.
6

Examine all wiring connections for corrosion or looseness. Tighten with a 5/16-inch socket if necessary. Replace any damaged wires.
7

Reassemble the dryer, plug it in, and test the heating function. Monitor the vent temperature; it should increase steadily within a few minutes.

Safety Warning:

Disconnect power to the dryer at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures are essential to prevent accidental electrocution. High voltage (240V AC) is present in the dryer's electrical components.

Prevention:

Clean the lint filter after every load. Regularly inspect and clean the dryer vent duct to prevent overheating and potential fire hazards. Annually, inspect the internal components, removing lint buildup with a vacuum cleaner. Check the venting for blockages every 6 months.

Expert Tip:

Many Admiral dryers have a diagnostic mode. Press and hold the Start/Pause and End of Cycle signal buttons simultaneously for 3 seconds to enter the service mode. This can display error codes and simplify troubleshooting.

Frequently Asked Questions

•What is the correct amp reading for the heating element when it's operating?

The amp reading should typically be between 8-12 amps for a standard 5600-watt heating element at 240V AC.

•How do I properly clean the dryer vent duct?

Use a dryer vent cleaning brush kit that attaches to a drill. Disconnect the duct from the dryer and the wall. Run the brush through the entire length of the duct, removing all lint buildup. Ensure the duct is reconnected securely to prevent leaks.

•My new thermal fuse keeps blowing. What could be causing this?

A repeatedly blowing thermal fuse indicates a restricted airflow, causing overheating. Check for a blocked vent, a kinked vent hose, or excessive lint buildup inside the dryer. Ensure the blower wheel is clean and rotating freely. If these are okay, there may be an issue with the motor windings.
