Dryer Stops Mid-Cycle: Overheating, Motor, and Sensor Causes
Updated
A dryer that starts normally and shuts itself off partway through is, most of the time, protecting itself from heat. The other causes are a sensor ending the cycle early and a loose connection. The pattern — when it stops, and whether it starts again on its own — points to which one.
Before you open anything: unplug the dryer. An electric dryer runs on a 240-volt circuit; a gas dryer also has a gas line — close the gas shut-off valve behind it before you move it or open the cabinet. If you smell gas, do not work on the dryer: leave the house, do not touch light switches, and call your gas utility from outside. Lint inside the cabinet is a fire hazard; vacuum it out while the panels are off.
It stops, then runs again after cooling down
That is a thermal overload doing its job. Something is making the dryer, or its motor, too hot.
- The vent. A clogged duct is the usual cause. Clean the lint screen, then the duct from the back of the dryer to the outside hood. Outside, with the dryer running, the flap should push open firmly. Long ducts, crushed foil ducts behind the dryer and bird nests in the hood all restrict airflow.
- Lint inside the cabinet. Lint that builds up around the blower and the heater housing traps heat. Vacuum it out with the panels off (unplugged).
- The drive motor. A motor with worn bearings runs hot. Its built-in overload switches it off after 10–20 minutes and lets it restart once it cools. If the vent is clear and the dryer still stops on a schedule like this, the motor is the suspect, often with a growl or squeal from the back of the dryer.
It stops for good partway through
- A thermostat or the thermal fuse. A cycling thermostat that fails can shut the heat off too early, and a thermal fuse that opens mid-cycle stops the dryer for good on many models. Test both for continuity with the dryer unplugged.
- The door switch. A worn switch, or a heavy load pressing on the door, can open the circuit mid-tumble. If tapping the door restarts it, the switch is the part.
It ends the cycle early, with clothes still damp
On auto-dry cycles, two metal bars inside the drum (usually just under the lint screen) sense moisture. Fabric softener sheets and residue coat them, and the dryer reads the load as dry. Clean the bars with a little rubbing alcohol on a cloth. If they are clean and the cycle still ends early, use a timed cycle to confirm, then look at the sensor and the control.
Power problems
A scorched terminal block or a loose wire where the power cord enters the dryer can cut power intermittently. If you see darkened or melted connections behind the cord cover, stop using the dryer: that is a fire risk, and the cord and terminal block need replacing.
Before you order the part
Dryer parts are model-specific, and gas and electric versions of the same dryer take different heating parts. The model plate is your only reliable source. On most dryers it is on the door frame, visible with the door open, or on the back panel. If you are not sure where to look, our model number guide shows each spot.
Ask before you install. Not sure it fits? Check your model number for free before you buy. Our fit check is optional; if it does not come back as a clear match, send us the full model number through Contact us before you order. Once a part has been installed we can only take it back if it arrived defective, we shipped the wrong item, or the listing was wrong on our end, and it has to come back in the condition it went out in. Checking first is faster than returning.
