What this usually is
The useful split on this roster is between a cycle that stops too soon and one that runs on indefinitely — opposite faults with a shared cause. A door switch releasing under vibration stops everything instantly and looks like a control fault. Note where in the cycle it fails, twice, before opening anything. The part numbers are deliberately left to the table, because they are the one thing that does vary here.
What the machine does
- An automatic cycle ends within minutes, load still wet — The moisture sensor is reading dry. Residue on the sensor bars is the usual explanation.
- An automatic cycle runs on and on — The machine cannot reach its dryness threshold, which points at airflow rather than at sensing.
- A timed cycle completes but the load is damp — Not a cycle fault at all: the machine ran exactly as instructed and the airflow was not sufficient.
- The drum turns but the heat comes and goes — A cycling thermostat or a cutout opening on temperature, which means the air is restricted.
- Cool-down runs but the heat never came on — The machine completed its programme without heating, which is a heating fault presenting as a cycle fault.
- NEAR MISS — nothing happens at all when started — A machine that never begins belongs on the start page for this family.
The ranking for this platform
- Moisture sensor bars coated with residue — First on this roster. The bars measure conductivity across a tumbling load, and a film of fabric softener insulates them, so the machine reads even a soaking load as dry and ends the cycle almost immediately.
- Restricted airflow — Second, and it produces the opposite symptom. A machine that cannot move air cannot remove moisture, so an automatic cycle never reaches its threshold and runs until it times out.
- Thermal cutout or cycling thermostat opening — The drum keeps turning and the heat stops, which reads as a cycle that never completes. The device is reporting restricted airflow rather than failing.
- Door switch releasing under vibration — A worn switch lets go when the machine shakes, and everything stops instantly. The tell is a failure that happens at random points rather than at a consistent stage.
- Overloading — Not a failure. A drum packed too full cannot tumble, so the load neither dries nor presents itself to the sensor, and the cycle behaves erratically as a result.
- Timer or control fault — Last. Genuine but uncommon, and confirming it means eliminating everything above it first — which is the whole point of the order on this page.
Work in this sequence
- Run a timed cycle instead of an automatic one — If a timed cycle dries the load properly, the sensing is at fault and the airflow is fine.
- Clean the lint filter and its housing — Airflow is the other half of this page, and the filter is the cheapest part of it to eliminate.
- Watch the vent hood outside while the machine runs — A flap that barely lifts means the machine cannot exhaust, which explains a cycle that runs for ever.
- Try a half load — Separates overloading from everything else in a single cycle and costs nothing to try.
What to do before the panel comes off
Safety
Isolation comes before inspection here. Unplug the appliance or trip its breaker, and assume every capacitor inside is still holding what it was holding. Never bridge a thermal cutout to keep a cycle running.

Where the owner line is
The owner line on this family is the cabinet panel. Cleaning bars and filters, clearing a duct and trying a smaller load are all yours. Testing a thermostat or a control board is not.
