Admiral Dryer Overheating: Troubleshooting Guide for... | appliancefaults.com

Technical Background:

The Dryer's Main Control Unit (MCU) relies on sensor feedback (thermistor) to regulate the heating element's on/off cycles via relays. Voltage flows from the breaker panel (240V AC) through the heating element and is controlled by the MCU based on temperature readings. Faulty sensors or a stuck relay can cause continuous heating.

Symptoms:

The dryer is producing excessive heat, clothes are scorching, and the exterior of the dryer is too hot to touch.

Possible Causes:

Clogged dryer vent
Faulty thermistor
Defective heating element
Malfunctioning high-limit thermostat
Stuck or shorted dryer relay

Solution:

1

Unplug the dryer from the outlet and disconnect the vent from the back.
2

Using a 5/16-inch nut driver, remove the rear access panel to expose the heating element, thermistor, and high-limit thermostat.
3

Inspect the thermistor. Using a multimeter, check its resistance. It should read approximately 10k ohms at room temperature (75°F). Replace the thermistor if the reading is significantly different.
4

Check the heating element for continuity with a multimeter. If the meter reads open (no continuity), the element is burned out and needs replacement. Observe for breaks in the coil.
5

Test the high-limit thermostat for continuity. It should have continuity at room temperature. If it does not, replace it. Check for tripped reset button.
6

Inspect the dryer vent for obstructions. Clean the vent and ductwork thoroughly to ensure proper airflow.
7

Reassemble the dryer, reconnect the vent, and plug it back in. Test its operation, monitoring the temperature to ensure it is within normal ranges.

Safety Warning:

Disconnect power before servicing. Lock Out/Tag Out (LOTO) procedures must be followed before beginning any repairs. The dryer operates on 240V AC, which can be lethal. Exercise extreme caution.

Prevention:

Clean the lint filter after every load. Inspect and clean the dryer vent at least once a year to prevent lint buildup. Periodically check the dryer's exhaust duct for kinks or obstructions.

Expert Tip:

Some Admiral dryers have a diagnostic mode. Consult the service manual (available online) for the specific model to access error codes and perform self-tests. This can help pinpoint the faulty component.

Frequently Asked Questions

•How do I access the diagnostic mode on my Admiral dryer?

The diagnostic mode sequence varies depending on the model. Consult the service manual or search online for the specific sequence for your Admiral dryer. It often involves pressing a combination of buttons in a specific order.

•What is the normal operating temperature range for an Admiral dryer?

A normal operating temperature for a dryer is between 135°F and 175°F. Temperatures exceeding this range indicate a problem.

•Where can I find replacement parts for my Admiral dryer?

Replacement parts can be found at appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your dryer's model number handy to ensure you order the correct parts.
