You press stop, you pull the plug on the timer dial, you even open and close the door twice, and the drum just keeps tumbling. It’s not a glitch you can wait out. Something in the circuit is stuck in the “on” position. So, you start wondering, “Why won’t my dryer turn off?”
A dryer that won’t turn off is usually a stuck push-to-start switch, a timer that won’t advance, a failed cycling thermostat, or a stuck relay on the control board.
Below are the seven causes worth checking, in order, along with what actually fixes each one.
Dryer Won’t Turn Off? Quick Answer
A few extra clues make this much faster to diagnose than most dryer problems, since each cause tends to behave a little differently.
| What You Notice | Most Likely Cause | Typical Fix |
|---|---|---|
| Dryer keeps running even with the door open | Stuck push-to-start switch | Replace the switch |
| Dryer runs well past the selected time | Timer motor not advancing | Replace the timer |
| Dryer runs continuously without cycling heat | Failed cycling thermostat | Replace the thermostat |
| Digital dryer ignores the stop or cancel button | Stuck relay on control board | Test and replace the board |
| Dryer only shuts off when unplugged | Selector switch stuck in run | Replace the selector switch |
| Runs fine, but door open doesn’t stop it | Door switch wiring fault | Test and repair wiring |
| Smell of burning plastic near the panel | Wiring short bypassing the timer | Call a technician |
7 Reasons Your Dryer Won’t Turn Off
Most of these issues trace back to one of two things: a mechanical switch that’s physically stuck, or an electrical component that’s stopped telling the rest of the dryer to stop.
1. Stuck Push-to-Start Switch
On dryers with a push-button start, that switch is really a relay behind the button. If the internal contacts weld together or the button itself gets stuck in, the motor circuit stays powered no matter what the timer or control board is telling it to do.
This is one of the more common causes on Whirlpool and Maytag models with a physical start button rather than a rotary dial. A direct-fit OEM push-to-start switch (View on Amazon) resolves this in most cases without needing to touch anything else.
2. Timer Motor Isn’t Advancing
On older mechanical dryers, a small motor inside the timer slowly turns the dial through the cycle. If that motor stalls or its gears strip, the dial stops moving, and the dryer keeps running because nothing ever tells it the cycle is finished.
If your timer knob hasn’t visibly moved in a while, even though the dryer is clearly still running, you may need to consider a replacement.
3. Failed Cycling Thermostat
On automatic-dry cycles, the cycling thermostat works with the timer to regulate heat and help move the cycle along. When it fails, the timer can stop advancing properly, which leaves the dryer running well past when it should have shut off. A replacement in this case may be necessary.
4. Stuck Relay on the Control Board
Digital and electronic dryers use relays on the control board instead of a mechanical timer. If a relay welds itself closed, the board keeps sending power to the motor and drum even after you press stop, cancel, or open the door.
Confirm this before ordering a board, since boards are the most expensive part on this list. A basic multimeter (View on Amazon) lets you test whether power is actually reaching the motor when it shouldn’t be, which points you toward the board rather than a simpler fix.
5. Worn Selector or Cycle Switch
The selector switch tells the dryer which cycle to run and when to stop. Years of turning it can wear the internal contacts until they stay closed even in the off position, so the only way to stop the dryer is to physically unplug it.
Selector switches vary significantly by brand and model, so it’s worth matching your dryer’s exact part number before ordering a replacement rather than assuming a universal fit.
6. Door Switch Wiring Fault
The door switch is supposed to cut power the instant the door opens. If a wire has come loose or corroded at the switch terminal, that safety signal never reaches the motor circuit, and the drum keeps spinning with the door wide open.
This is a genuine safety issue, not just an inconvenience, and it’s worth testing and repairing immediately rather than working around it.
7. Wiring Short Bypassing the Timer
Less common, but serious: a damaged wire inside the control panel can create a direct path around the timer or control board entirely, feeding constant power to the motor. A burning smell near the control panel is the biggest warning sign here.
This one is genuinely a job for a licensed technician, since diagnosing a short safely means working inside a live control panel.
How to Diagnose a Dryer That Won’t Turn Off Safely
Working through these in order gets you to the actual cause fastest, without opening panels you don’t need to touch.
- Unplug the dryer immediately if you smell burning or see smoke, and skip straight to calling a technician.
- Open the door while the dryer is running. If it doesn’t stop, the door switch or its wiring is suspect.
- Watch the timer dial on mechanical models for several minutes to see if it’s actually advancing.
- Press the start button in and out a few times on push-button models to check for a stuck switch.
- Test for power at the motor with a multimeter once the simpler causes are ruled out.

DIY Repair vs. Calling a Technician
Most of these repairs are safe for a confident DIYer, but a few genuinely aren’t, and it’s worth knowing the difference before you start.
| Factor | DIY Repair | Professional Repair |
|---|---|---|
| Typical cost | $15–$60 in parts | $150–$350 including labor |
| Time required | 20–45 minutes | Same day to a few days |
| Skill level | Basic hand tools, some wiring knowledge | None required |
| Best for | Push-to-start switch, timer, thermostat | Wiring shorts, control board diagnosis |
| Safety note | Always unplug before testing | Required for suspected wiring shorts |
Dryer Won’t Turn Off: Quick Answers
Is it dangerous if my dryer won’t turn off?
Yes, especially if it keeps running with the door open or you smell anything burning. Unplug it immediately in either case rather than waiting to diagnose the exact cause.
Why does my dryer keep running after I open the door?
This points to a door switch that isn’t cutting power, either from worn contacts or a loose wire. It’s a safety issue, so it’s worth addressing before running the dryer again.
Can a dirty lint filter make my dryer not turn off?
No. A clogged lint filter causes overheating and long dry times, but it doesn’t affect the timer, switches, or relays that control when the dryer stops.
Why does my dryer run past the time I set?
On mechanical models, this usually means the timer motor has stalled or the cycling thermostat has failed. On digital models, it more often points to a stuck relay on the control board.
Is a dryer that won’t turn off worth repairing, or should I replace it?
If the cause is a switch, timer, or thermostat, repair is almost always cheaper and faster than replacement. A failed control board on an older unit is the one case worth comparing against the cost of a new dryer.
Fixing a Dryer That Won’t Turn Off for Good
A dryer that won’t turn off almost always comes down to a stuck switch, a stalled timer, or a relay that’s welded closed, all fixable without a full technician visit in most cases. Unplug it if you notice burning or an open door not stopping it, then work through the causes above in order. Once you’ve matched the symptom to the part, this is usually a same-afternoon fix.
