When a dryer continually trips the circuit breaker, your clothes can’t fully dry and something clearly needs repair. This dryer troubleshooting guide from Fix4U Repairs will cover how to diagnose and fix the common causes of dryers tripping breakers.

What Causes a Dryer to Keep Tripping the Breaker?

These are the most likely culprits for dryers tripping breakers:

Overloaded Circuit

If too many appliances share the circuit, the dryer’s power draw may overload and trip the breaker.

Short Circuit 

If wires inside the dryer touch or insulation fails, it can create a short drawing of high amps and trip the breaker.

Faulty Heating Element

A partially broken heating element that contacts the housing can short, instantly tripping the breaker.

Damaged Power Cord

Fraying or exposed wires in a damaged power cord can touch, causing a short that trips the breaker.

Bad Thermal Fuse

If the thermal fuse blows, it cuts all power to the dryer to protect from overheating fires.

Defective Motor

If the motor is damaged, it will draw significantly more current and trip the breaker.

Loose Electrical Connections

Heat and vibration can loosen internal wires over time, causing resistance and shorts.
