Dryer: Why doesn't my dryer work?

If the dryer shows no signs of life (the digital display is dead or the drum light doesn't turn on when you open the door on a dryer with a dial timer), check the house circuit breaker and reset it if tripped. For a gas dryer, you can test the outlet by plugging a night light or small appliance into it.

If the dryer's electrical outlet works, then a bad power cord, failed timer or faulty electronic control board can prevent the dryer from working. These videos can help you figure out how to fix your dryer when it's completely dead.

THESE REPAIRS MAY HELP SOLVE YOUR DRYER PROBLEM

Replace the dryer timer

The timer on the control panel lets you set the drying time by turning the timer's control knob. A small motor on the back of the timer advances the timer during the cycle. The timer's internal cams open and close switches or contacts to operate the various electro-mechanical components in the dryer (mainly the drive motor and the heating element). Replace the timer if the contacts aren't working, the dryer won't start, heat or continue running, or the timer won't advance.

Repair or replace the dryer electronic control board

The electronic control board governs the timing and execution of dryer functions. The wiring connections on the control board can be repaired, but the control board itself cannot. Replace the electronic control board if it's receiving voltage but isn't transmitting it to the dryer components, causing the dryer to not work. The dryer may start but then stop in the middle of the cycle if internal control board components don't detect sensor signals accurately. It can be difficult to determine if the electronic control board is the problem (unless you see burn marks on it) and it's an expensive part that can't be returned once installed; for that reason, have a trained service technician perform advanced diagnostics on control board before you replace it.
