Clothes dryer won’t stop spinning: causes, part cost
Prices checked 2026-08-28
A clothes dryer won't stop spinning is most often a timer or cycle control fault problem - about 34% of reported jobs. Here is how to confirm it, what the part costs, and when to stop.
A clothes dryer is a simple machine: drum, heat, airflow. Because the heat is intense and the airflow path is long, most dryer faults are airflow faults – which is also why a surprising number of dryer problems are fixable without replacing parts.
Clothes dryer won't stop spinning is one of the most common repair searches there is. A machine that spins when it should not, or keeps spinning after the cycle ends, usually has a stuck switch or relay holding the spin circuit closed. It is an electrical fault, but a contained one.
Before you call anyone: 30-second checks
- Cancel the cycle and unplug the machine before inspecting anything.
- Check the lid or door switch – a stuck switch can keep the spin circuit live.
- Check the timer or control board relay if the machine spins in every position.
The likely causes, ranked
Timer or cycle control fault
About 34% of clothes dryer won't stop spinning jobs come back to this cause. The control board, timer or sensor is the brain of the unit, and it fails by misbehaving rather than dying – wrong readings, stuck relays, forgotten cycles.
How to confirm it: Look for error codes, behaviour that changes with settings, and any burnt smell near the board; boards are the last part to blame and the last to buy.
Typical fix: $90. A capable DIYer can usually handle this one. You would be looking for a timer.
Lid or door switch stuck closed
About 26% of clothes dryer won't stop spinning jobs come back to this cause. Switches and interlocks tell the unit it is safe to run, and a stuck or failed switch can stop a unit dead or leave it running when it should not.
How to confirm it: A unit that will not start, or starts only when the door is held, points at the interlock switch – a cheap, common part.
Typical fix: $40. A capable DIYer can usually handle this one. You would be looking for a lid switch.
Stator or brake assembly fault
About 22% of clothes dryer won't stop spinning jobs come back to this cause. This is a component-level failure – the part itself has worn out or failed, which is why it sits on the ranked list rather than the free-check list.
How to confirm it: It is worth confirming with a multimeter or a visual check before ordering the part, and worth asking the shop if the part is returnable.
Typical fix: $120. This one is best left to a professional. You would be looking for a stator.
Control board relay stuck
About 18% of clothes dryer won't stop spinning jobs come back to this cause. A motor, fan or pump with its drive components is a wear item – belts stretch, bearings dry out, capacitors lose their charge and relays stick.
How to confirm it: Listen for the motor: a hum with no movement points at a capacitor or belt; a grinding or squeal points at a bearing. Each has a different price tag.
Typical fix: $180. This one is best left to a professional. You would be looking for a control board.
When to stop and call a pro
A machine that spins with the lid open is a safety fault – do not reach in, unplug it and call a trade.
How to keep it from coming back
This one is rarely a wear item – it is usually a switch or relay that failed. Not much prevents it beyond avoiding power surges on the circuit.
Bottom line: Clothes dryer won't stop spinning is worth diagnosing before you call anyone – the free checks above catch a surprising share of cases, and the ranked list tells you what the part should cost if it is not one of them. Run the figures through the repair-or-replace test on this page before you authorise any work, and never pay for a diagnosis without getting the part name and the price in writing first.

Frequencies are the share of reported jobs attributed to each cause across repair-platform and forum data - a starting point for diagnosis, not a certainty.
What this should cost to put right
Across the causes listed above the repair runs $40 to $180. A quote far above the top of that range is usually a diagnosis of convenience - get a second opinion before you authorise it.
Repair it, or replace the unit?
This is the number people get wrong most often, and it costs them the most. Run the quote through the test - it uses the mid-point cost of the fix above against a new unit and the years this one has left.
REPAIR IT
The repair is 12% of a new unit and the appliance has roughly 5 year(s) of expected life left. Fixing it is the economical call. A new unit would save about $45/year in running costs, so keep repairing until that pays back in under 5 years.
Decision rule: repair when the fix costs under 50% of a replacement and the unit is under 70% through its expected life.

Common questions
Is it dangerous if my clothes dryer has a "won't stop spinning" problem?
Usually not immediately - none of the likely causes on this page involve gas, fuel or a mains electrical fault. The two cautions that apply everywhere: keep water away from any electrical point, and if you ever smell gas or burning, stop diagnosing and call a professional.
How much does it cost to fix a clothes dryer with a "won't stop spinning" problem?
Most fixes for this run $40 to $180. The most common cause, timer or cycle control fault, runs about $90 to put right, and the part you would be looking for is timer. Get the diagnosis in writing before authorising anything above the top of the range.
Why does my clothes dryer have a "won't stop spinning" problem?
In about 34% of reported cases it is a timer or cycle control fault. It is the first thing to check because it is the most common - and usually the cheapest. If that checks out clean, work down the ranked list on this page before paying for a diagnosis.
Should I repair or replace my clothes dryer?
Repair it when the fix costs under half of a replacement and the unit is under 35% through its roughly 13-year expected life. Past that point a repair is usually a deposit on the next failure - run the test on this page with your actual quote before you decide.
