A dryer won't start means you pressed start, the way that model's manual describes, and the drum did not move. A dryer not turning on, why won't my dryer start, and a dryer not starting are that report. Separate it from the two faults people mix in. A dryer that tumbles and does not get hot belongs in dryer not heating. A dryer that heats and does not tumble belongs in dryer not spinning but heating, and it should be unplugged because heat without moving air can scorch clothes. A squeak after the drum is already turning is dryer squeaking.
Door, press, and breaker
Close the door until it latches. A sock in the latch is enough to keep the start circuit open. Do not tape the door switch and do not hold it down with a tool. If the manual describes a control lock or a start that has to be pressed and held, use that page for this model. There is no one button for every brand. Brand start-button notes stay with that brand's later guides.
Many U.S. electric dryers use a double-pole 240-volt breaker. Switch it fully off, then on, once. If it trips again, stop and call an electrician. Do not keep resetting it. A gas dryer still needs 120 volts for the motor, but the heat is a burner. If you smell gas, leave the house and call the gas utility. Do not adjust a gas valve and do not look for a leak with a flame.
Power before parts
Confirm the laundry room has other power. A dark room is the breaker or the house, not a dryer belt. Unplug an electric dryer, or shut its breaker off, before you pull the cabinet out. The cord and the vent are both easy to crush. Do not remove the door switch, the thermal fuse, or a motor to "see if it starts." Replacing a thermal fuse without a clear vent is how the new fuse opens. Vent cleaning is how to clean a dryer vent, and it matters after the dryer runs again, not as a way to jump a dead start.
| What you see | Likely cause | Safe check |
|---|---|---|
| Nothing at all when you press start | Door, control lock, or power | Latch the door. Read this model's start step. Check the breaker once |
| Drum turns, no heat | Not a start failure | Use the not-heating guide |
| Heat, drum still | Not a start failure | Unplug. Use the not-spinning guide |
| Breaker trips as soon as it is reset | Electrical fault | Stop. Call an electrician |
| Smell of gas | Leave | Call the gas utility. Do not touch a gas valve |
Checks in order
Latch the door
Clear the strike. Do not bypass the switch.
Use this model's start step
Some controls want a press and hold. Read the manual. Skip a sequence from a different badge.
Reset the breaker once
Off, then on. If it trips again, call an electrician. Gas smell means leave and call the utility.
Unplug before you move the dryer
Do not pull it by the vent or the cord. Leave the cabinet closed.
Stop at the door switch and the motor
Those parts, and a thermal fuse, are not a home bypass. A technician can test them with the dryer unplugged.
Questions readers ask
Why won't my dryer start if the light inside the drum is on?
The door may be open enough to light the lamp and still not latch the start circuit. Close it fully. If the manual wants a press-and-hold start, a tap is not that step. Do not tape the door switch.
The dryer won't start, but last week it ran and stayed cold. Which is it?
If the drum will not turn now, use this page. If the drum turns and the clothes stay wet and cold, use the not-heating guide. They are different circuits.
Can I push the door switch with a screwdriver to test it?
No. That bypasses a switch that keeps the drum from turning while the door is open. Leave the switch in place.
Should I replace the thermal fuse because the dryer is dead?
Not from this page. A fuse is not a guess, and a new fuse on a blocked vent fails again. If the drum does not start, the door, the manual's start step, and the breaker come first.
