Admiral Dryer Blowing Fuses or Tripping Breaker:... | appliancefaults.com

Technical Background:

The dryer's main control unit (MCU) receives power through the breaker panel, typically a 240V circuit using two 120V legs. When a component shorts to ground, it creates a low-resistance path, causing excessive current flow. This overcurrent exceeds the breaker's or fuse's rating, causing it to trip or blow, interrupting the circuit to protect against fire and electrical shock.

Symptoms:

The homeowner reports that the Admiral dryer immediately trips the circuit breaker or blows a fuse when the dryer is turned on, or shortly after it starts running. This may happen with or without a load of clothes inside. The homeowner may also notice a burning smell.

Possible Causes:

Overloaded circuit
Shorted heating element
Faulty motor
Defective terminal block
Damaged wiring harness
Grounded components

Solution:

1

Unplug the dryer from the outlet.
2

Locate the breaker panel and confirm the breaker is tripped or the fuse is blown. Replace the fuse or reset the breaker. If it trips again immediately, proceed.
3

Remove the rear access panel of the dryer. Disconnect the wires from the heating element.
4

Using a multimeter set to Ohms, test the heating element for continuity to ground. A reading other than infinite resistance indicates a short to ground.
5

Inspect the motor windings for shorts to ground. Disconnect the motor wires and test each winding to the motor frame. Replace the motor if a short is detected.
6

Examine the terminal block where the power cord connects to the dryer. Look for loose or burned connections. Tighten or replace the terminal block as needed.
7

Check the wiring harness for any signs of damage, such as frayed wires or burned insulation. Repair or replace the harness.

Safety Warning:

Disconnect the dryer from the power source (unplug it) and Lock Out/Tag Out (LOTO) the breaker before performing any repairs. Dryer circuits operate at 240V AC, which can cause serious injury or death. If you are not comfortable working with electricity, consult a qualified appliance repair technician.

Prevention:

Regularly clean the lint filter after each load. Inspect the dryer vent duct for clogs and restrictions at least twice a year. Ensure the dryer is connected to a dedicated 240V circuit with the correct amperage rating.

Expert Tip:

Many Admiral dryers have a diagnostic mode. Check the tech sheet (usually located behind the kick panel or inside the control panel) for the specific sequence to enter service mode. This can provide error codes to pinpoint the fault.

Frequently Asked Questions

•What is the resistance reading I should expect from a good heating element?

A good heating element typically reads between 9 and 13 Ohms. An open circuit (infinite resistance) indicates a broken element, while a very low resistance indicates a short.

•How do I check the dryer vent for clogs?

Disconnect the vent duct from the dryer and the wall. Use a vent brush or vacuum to remove lint buildup. Inspect the entire length of the duct for kinks or obstructions. Rigid metal ductwork is preferred over flexible plastic or foil ducts, as they are less prone to clogging.

•What size breaker should be used for an Admiral dryer?

Most Admiral dryers require a 30-amp, double-pole breaker on a dedicated 240V circuit. Consult the dryer's specifications or the nameplate on the dryer for the exact requirement.
