Admiral Dryer Door Switch Bypass: Testing and Motor... | appliancefaults.com

Technical Background:

The door switch is a critical safety component. When the door is closed, the switch completes a circuit allowing voltage (typically 120V AC) to reach the motor start circuit or control board. The MCU monitors the door switch circuit to ensure the door is properly closed before allowing the motor to start. An open circuit (door open) prevents the dryer from running.

Symptoms:

The Admiral dryer won't start, or stops intermittently. It may show signs of power but the drum won't turn, and the motor won't engage. Some users report the start button does nothing at all.

Possible Causes:

Faulty door switch
Broken door switch actuator
Wiring harness damage near the door switch
Control board malfunction not reading the switch
Loose or corroded connections
Motor overload impacting the start circuit

Solution:

1

Disconnect power to the dryer at the breaker panel.
2

Locate the door switch assembly, typically near the door frame.
3

Use a multimeter to check the continuity of the door switch in both open and closed positions. Note the readings.
4

WARNING: For testing purposes only, create a temporary bypass by disconnecting the wires from the door switch. Use an insulated jumper wire to connect the two terminals. DO NOT leave the dryer unattended while bypassed. Never permanently bypass the switch. This is a critical safety device.
5

Restore power to the dryer at the breaker panel.
6

Attempt to start the dryer. If the motor now runs, the door switch or its circuit is likely the problem. If the motor still does not run, investigate the motor, thermal fuse, centrifugal switch or control board.
7

Disconnect power and REMOVE the jumper wire immediately after testing. Replace the faulty door switch with a new one.

Safety Warning:

Always disconnect power to the dryer at the breaker panel before performing any repairs. Use proper Lock-Out Tag-Out (LOTO) procedures. The dryer operates on 120V AC or 240V AC; improper handling can lead to serious injury or death.

Prevention:

Avoid slamming the dryer door. Periodically inspect the door switch and surrounding wiring for damage. Clean any lint buildup around the switch area. Check the door striker and ensure it's properly aligned.

Expert Tip:

Some Admiral dryers have a diagnostic mode. Try pressing and holding the 'Start' and 'End of Cycle' buttons simultaneously for 3 seconds. This may display error codes related to the door switch or motor circuit.

Frequently Asked Questions

•What voltage should I expect to see at the door switch when the door is open and closed?

You should see 120V AC on one side of the switch when the dryer is powered on. When the door is closed, the voltage should pass through the switch to the other terminal.

•What if the motor runs with the door switch bypassed, but the dryer still doesn't heat?

If the motor runs, but there's no heat, check the heating element, thermal fuse, thermostats, and any associated wiring. Use a multimeter to test for continuity in these components.

•Where is the thermal fuse located, and how can I test it?

The thermal fuse is typically located on the blower housing. Disconnect power to the dryer, then remove the wires from the thermal fuse. Use a multimeter set to continuity to check if the fuse is open (no continuity) or closed (continuity). If it's open, replace it.
