Quick answer
A dryer that will not turn on at all usually has a tripped breaker, a dead outlet or a blown thermal fuse. One that lights up but will not start usually has a faulty door switch, start switch or control lock on. A hum with no tumble means a broken belt, a seized pulley or a failing motor, so stop pressing start. Check the breaker, the door and the control lock first; if it still will not start, an appliance technician tests the switch, fuse and motor. Call (888) 217-0236 to reach an appliance repair company taking calls in your ZIP; the line is answered 24/7.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.

When a dryer does nothing at all, no hum, no light, no tumble, the fault is usually power or a safety switch, and two of the four checks below take less than a minute. When the panel lights up but the drum will not start, the fault is more often the door switch, the belt or the motor.
Four Checks Before You Call
- 1Power at the outlet and the breaker. Electric dryers use a 240-volt double breaker; reset it fully off, then on. Gas dryers plug into a normal 120-volt outlet, so test that outlet with a lamp.
- 2The door switch. Press the door firmly shut. Most dryers will not start with the door switch open, and a broken striker or switch is one of the common causes of "won't start".
- 3Control lock and the start button. Many models have a control lock (often a held button with a padlock icon) and some need the start button held for two or three seconds.
- 4Listen when you press start. A hum with no tumble usually means the motor is trying to turn against a broken belt, a seized roller or a jammed drum. Stop pressing start so the motor does not overheat.
What Each Sign Points To
| What you see | Likely cause | Next step |
|---|---|---|
| Nothing at all: no light, no sound | Tripped breaker, failed outlet, blown thermal fuse (on many models it cuts the whole dryer) | Check the breaker, then a technician |
| Lights on, nothing when you press start | Door switch, start switch, control board | Technician |
| Hums, drum does not turn | Broken belt, seized idler pulley or motor | Technician |
| Runs a few seconds then stops | Motor overheating, restricted vent | Clear the vent, then a technician |
| Starts, then shuts off mid-cycle | Overheating from lint, failing motor | Technician, and clean the vent |
On many dryers the thermal fuse cuts power to the motor as well as the heat, so a dryer that died after long, hot drying times often has a blocked vent behind the fault. Have the duct checked at the same visit.

Frequently Asked Questions
Why is my dryer not turning on but has power?
If the panel lights but nothing happens, the usual causes are the door switch, the start switch, the control lock or the control board. On many dryers a blown thermal fuse also stops the motor.
What does it mean when a dryer hums but won't turn?
The motor is trying to start against a drum that will not move: a broken belt, a seized idler pulley or a jammed drum. Stop pressing start to avoid overheating the motor.
How much does it cost to fix a dryer that won't start?
Typical dryer repairs run $100–$430 according to Angi. A door switch or belt costs less than a motor or control board.
Should I reset the breaker on my dryer?
YesSwitch the double breaker fully off, then on. If it trips again, call a technician rather than resetting it repeatedly.
