Admiral Dryer Taking Two Cycles to Dry: Troubleshooting... | appliancefaults.com

Technical Background:

The Admiral dryer's MCU (Main Control Unit) monitors the heating element, thermostats, thermistors, and moisture sensor to regulate the drying cycle. Voltage paths through these components must be intact for proper operation. The MCU uses resistance values from the thermistor to determine the temperature and adjust cycle time. Incorrect readings trigger extended drying times.

Symptoms:

The homeowner reports that their Admiral dryer now requires two full cycles to completely dry a normal load of clothes. Clothes are damp and sometimes still cold after the first cycle.

Possible Causes:

Clogged lint screen or exhaust duct
Faulty heating element
Defective thermostat or thermistor
Restricted airflow through blower wheel
Malfunctioning moisture sensor
Weak or worn drum seal

Solution:

1

Unplug the dryer from the outlet or turn off the breaker at the breaker panel.
2

Clean the lint screen thoroughly. Inspect the exhaust duct for clogs or restrictions. Ensure there are no kinks or crushed sections in the duct. Maximum recommended duct length is 25 feet with no more than 4 90-degree elbows.
3

Check the heating element for continuity using a multimeter. A reading of infinite resistance indicates a failed element. The element should measure approximately 9-12 ohms.
4

Test the thermostat and thermistor using a multimeter. Compare readings to the manufacturer's specifications. Room temperature thermistor resistance should be in the range of 10k-50k ohms. Check the high-limit thermostat for continuity; it should have a reading of 0 ohms.
5

Inspect the blower wheel for obstructions. Remove any lint or debris. Ensure the blower wheel spins freely.
6

Examine the moisture sensor for damage or corrosion. Clean the sensor with a soft cloth or fine-grit sandpaper. Verify continuity across the sensor when wet and open circuit when dry.
7

Inspect the drum seal for wear or damage. Replace if necessary. A worn seal allows heated air to escape, reducing drying efficiency.

Safety Warning:

Always disconnect power to the dryer before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energizing of the circuit. The dryer operates on 240V AC, which can cause serious injury or death.

Prevention:

Clean the lint screen after every load. Regularly inspect and clean the exhaust duct at least twice a year. Check the dryer vent outside to ensure it's not blocked by snow, debris, or bird nests.

Expert Tip:

Some Admiral dryers have a diagnostic mode. Refer to the service manual for instructions on accessing this mode and interpreting the error codes. Often, simultaneously pressing and holding the 'Start' and 'Cancel' buttons for 3 seconds will enter the diagnostic mode.

Frequently Asked Questions

•What is the resistance range of a typical Admiral dryer heating element?

A typical Admiral dryer heating element should measure approximately 9-12 ohms.

•How do I properly clean the moisture sensor?

Clean the moisture sensor with a soft cloth or very fine-grit sandpaper. Avoid using harsh chemicals or abrasive cleaners.
