The short answer
A compact dryer that stops part-way through is usually protecting itself, and most often because of this: a restricted duct is overheating the machine into a cut-out. Next on the list: the drum is overloaded. How long it needs before it will restart tells you which protector tripped.
What you observe
- The cycle stops before the load is dry — Note whether it restarts straight away or needs a long rest.
- It stops mid-cycle and will not restart until it is cold — Thermal protection is the only thing that behaves that way.
- Large loads stall and small ones finish normally — Load size is the only variable that changed.
- The cycle finishes early and the clothes are still damp — The machine believed the load was dry, so it stopped.
- NEAR MISS — the cycle finishes and the clothes are still wet — That is a sensor or an airflow question rather than a stall, and it reads differently.
Causes, most likely first on this machine
- A restricted duct is overheating the machine into a cut-out — First where the machine stops part-way and will restart only after it has cooled. That pattern is a thermal cut-out doing its job: the duct cannot shift the exhaust, the temperature climbs past the limit, and the machine protects itself.
- The drum is overloaded — Ranked here because it is free to test and it explains a machine that is fine on small loads.
- The moisture sensor is reading the load as already dry — Ranked here because it produces an early finish rather than a fault, which is the exact symptom people describe.
- The lint filter is restricting enough to trip the machine — Last, but do the water test on the screen before pulling a duct off the wall.
Check in this order, and why
- Note whether it will restart only after cooling down — A cut-out resets on temperature, which is the giveaway.
- Try the same washing as two smaller loads — A machine that is fine on half a load is not faulty.
- Wipe the sensor bars inside the drum with vinegar — A softener film makes wet fabric read as dry.
- Pour water on the lint screen and see whether it passes — The screen is upstream of the duct, so check it first.
What an owner can safely check
- Note where it stops and how long before it will restart — An immediate restart and a long cool-down mean different protectors.
About 60 min
- Clear the whole duct run and the outside flap — Then run a full cycle and see whether it completes.
Tools: vacuum, torchAbout 45 min
- Run the same washing as two half loads and compare — The drum needs room to tumble, not just to hold.
About 60 min
- Clean the metal sensor bars in the drum with a little vinegar — Then run an automatic cycle and compare.
Tools: cloth, vinegarAbout 15 min
- STOP HERE before testing any thermostat or cut-out — Those tests are made on live terminals and they are not owner work.
Before you open anything
Safety
Unplug the machine or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and a dryer that has just cut out on temperature is hot inside long after it is silent. Never run the machine with the duct disconnected for longer than the few seconds a test takes — exhaust indoors carries lint and moisture into the room. And never restart a machine that has cut out on temperature until it is fully cold.
When to call a technician
Call once the filter, the duct or the tank are all clear and it still stops part-way. A machine cutting out repeatedly on temperature is being protected for a reason, and that reason needs finding. Call immediately if the cabinet or the load is too hot to handle when it stops, and do not restart it until it is cold.

What this page does not cover
This page is written for the brand and the machine class, not for one family or model line. Where a family- or model-specific page exists for your machine, that page is the more specific answer. Deliberately absent: duct diameters, capacity figures, glide and belt part identifiers and wiring colours, which differ between the wall-vented and window-vented families.
