Dryer Tripping the Breaker: Common Causes and How to Fix It
If your dryer repeatedly trips the circuit breaker, it indicates an electrical fault that is drawing too much current or causing a short circuit. Continuing to reset the breaker without identifying the cause can create a safety hazard.
Before replacing parts, confirm the dryer is on a dedicated circuit rated for its power requirements. If the problem continues, the following are the most common causes of a dryer tripping the breaker and the recommended solutions.
1. Dryer Heating Element Short
Most Common Solution
Why It Causes the Breaker to Trip
A shorted heating element can draw excessive current and trip the breaker, especially when the heat cycle begins.
Common causes include:
- Burned-out element with exposed wire
- Damaged insulation
- Moisture contact
Symptoms include:
- Breaker trips shortly after starting a heat cycle
- Burning smell near the heating assembly
- Visible scorch marks on the element
How to Replace a Dryer Heating Element
- Disconnect power to the dryer.
- Remove the rear or front panel to access the heating assembly.
- Disconnect the wiring from the heating element.
- Remove the mounting screws or clips.
- Remove the old heating element.
- Install the replacement element.
- Reconnect the wiring and reassemble the panel.
- Restore power and test operation.
2. Dryer Wiring or Power Cord Damage
Why It Causes the Breaker to Trip
Frayed or damaged wiring can create a short circuit that trips the breaker.
Common causes include:
- Worn power cord insulation
- Rodent damage
- Pinched wiring behind the dryer
Symptoms include:
- Breaker trips intermittently
- Visible wire damage or fraying
- Burning smell near the power cord
How to Replace a Dryer Power Cord
- Disconnect power to the dryer at the outlet.
- Remove the access panel covering the power cord connection.
- Disconnect the old power cord from the terminal block.
- Remove the strain relief clamp.
- Install the replacement power cord and strain relief.
- Reconnect the wiring to the terminal block.
- Reassemble the access panel.
- Restore power and test operation.
3. Dryer Motor Short or Overload
Why It Causes the Breaker to Trip
A motor with shorted windings or a mechanical jam that forces the motor to overwork can draw excessive current and trip the breaker.
Common causes include:
- Shorted windings
- Seized motor bearing
- Jammed drum
Symptoms include:
- Breaker trips when the dryer starts
- Motor hums loudly before tripping
- Burning smell from the motor area
How to Replace a Dryer Motor
- Disconnect power to the dryer.
- Remove the front or rear panel to access the motor.
- Remove the drive belt from the motor pulley.
- Disconnect the motor wiring.
- Remove the mounting bolts securing the motor.
- Remove the old motor.
- Install the replacement motor.
- Reconnect wiring and reinstall the belt.
- Reassemble the panel and test operation.
4. Overloaded Circuit or Undersized Breaker
Why It Causes the Breaker to Trip
If the dryer shares a circuit with other high draw appliances, or the breaker is undersized for the dryer's electrical requirements, it may trip under normal operation.
Common causes include:
- Shared circuit with other appliances
- Incorrect breaker size
- Aging electrical panel
Symptoms include:
- Breaker trips when multiple appliances run together
- Breaker trips consistently regardless of dryer condition
- Breaker feels warm to the touch
How to Address an Overloaded Circuit
- Confirm the dryer is on a dedicated circuit.
- Check that the breaker rating matches the dryer's electrical requirements.
- Avoid running other high draw appliances on the same circuit.
- Have a licensed electrician inspect the circuit and panel.
- Replace the breaker or wiring if recommended by a professional.
Preventing Dryer Breaker Trips
To help prevent your dryer from tripping the breaker:
- Have electrical connections inspected periodically.
- Avoid overloading shared circuits.
- Address burning smells immediately.
- Keep the dryer on a dedicated circuit.
- Schedule periodic maintenance.
- Replace worn power cords promptly.
Find the Correct Dryer Replacement Part
A dryer that trips the breaker is commonly caused by a shorted heating element, damaged wiring or power cord, a motor short or overload, or an overloaded or undersized circuit.
