A dryer that is completely dead is often missing power. Electric dryers use a 240-volt circuit, and one side of a double breaker can trip in a way that leaves symptoms confusing.
This applies to electric and gas dryers from most brands.
Does this affect you?
Use this if pressing Start does nothing: no hum, no drum light, no display, and no motor sound.
Check power at the source
- Go to the breaker panel and find the dryer breaker.
- For electric dryers, look for a double-pole 240V breaker and switch it fully off, then back on.
- Make sure the dryer plug is fully seated if the outlet is accessible.
- Reset any GFCI outlet feeding the laundry area.
- Test an accessible outlet with another device if possible.
- Remember that gas dryers still need electricity for the motor, controls, and igniter.
Turn off the breaker before moving the dryer or opening any panel. Electric dryer circuits are 240 volts. If you smell gas near a gas dryer, leave the area and call the gas utility from outside.
Check the door and start switches
- Open and close the door firmly and listen for the door switch click.
- Remove clothing caught in the door seal.
- Press and hold the Start button or knob a little longer than usual.
- If the door switch is visible in the frame, confirm it moves freely.
- If pressing the door firmly changes behavior, the door switch may be worn or misaligned.
If power is confirmed and the door switch seems normal, an internal safety part may have opened. A thermal fuse can cut power after overheating, often because the vent was clogged. Thermostats can fail too.
Testing these parts usually means opening the dryer and using a multimeter. If you have already confirmed power and cleaned the vent, call an appliance technician to test the fuse, thermostat, start switch, and control board.
