Quick Checks

1

Check the Power Cord

Make sure the dryer's power cord is securely plugged into the outlet. Sometimes it can get bumped or loosened.

2

Check the Circuit Breaker

Locate the circuit breaker for the dryer in your electrical panel and ensure it hasn't tripped. Reset it if necessary.

3

Check the Door Switch

Open and firmly close the dryer door. A faulty door switch can prevent the dryer from starting if it doesn't register that the door is closed.

4

Check the Start Button

Press and hold the start button firmly for a few seconds. Some dryers require a sustained press to initiate the cycle.

Common Causes

Tripped Circuit Breaker

DIY

Dryers use a lot of electricity. Overloading the circuit can cause the breaker to trip, preventing the dryer from starting. Try resetting the breaker. If it trips immediately again, there may be a larger electrical issue.

Faulty Door Switch

Call Pro

The door switch tells the dryer the door is closed. If it's broken, the dryer won't start as a safety measure. You can test the switch with a multimeter, but replacement is usually best left to a professional.

Defective Start Switch

Call Pro

The start switch itself could be faulty. If it's not sending the signal to start the motor, the dryer won't turn on. Testing requires a multimeter and some electrical knowledge.

Blown Thermal Fuse

Call Pro

The thermal fuse is a safety device that blows if the dryer overheats. If it's blown, the dryer won't start. This often indicates a venting problem that needs to be addressed.

Motor Problems

Call Pro

A failing dryer motor can prevent the dryer from starting. Motors can wear out over time, or their start windings can fail. This requires professional diagnosis and repair.

Control Board Issues

Call Pro

The control board manages all the dryer's functions. A malfunctioning control board can prevent the dryer from starting. Diagnosis and repair of control boards require specialized knowledge.

When to Call a Professional

  • If the circuit breaker trips repeatedly after resetting it.
  • If you suspect a faulty door switch, start switch, or thermal fuse and don't have experience with electrical repairs.
  • If you suspect a motor problem or control board issue.
  • If you are not comfortable working with electricity.

Safety Warning

Working with electrical appliances can be dangerous. Always disconnect the power cord before attempting any repairs. If you are not comfortable working with electricity, call a qualified technician.
