The short answer
A cycle that stops early, restarts or never ends on the USDR line is usually the machine responding to what its sensors report rather than a broken programmer. Moisture sensor bars coated in softener residue are the leading cause: they read a dry load and end the cycle in minutes. Cleaning them takes a cloth. This is a wide family, and the order below is what its construction dictates rather than what the brand as a whole does.
What you observe on these models
- The machine stops mid-cycle and restarts if left to cool — Thermal protection opening and resetting, which means the machine is overheating rather than miscounting.
- The display advances far too quickly at the start — Remaining-time estimates are calculated from sensed dryness, so a bad reading shows up as a collapsing countdown.
- The cycle runs its full time and the load is still damp — Airflow or heat rather than sensing — the machine did what it was told and the conditions were wrong.
- It pauses, hums and then continues — A motor protector cycling, which usually means the drum is dragging or the machine is overloaded.
- NEAR MISS — the machine will not begin a cycle at all — That is a start fault rather than a cycle fault, and it belongs on a different page.
Causes, most likely first on the USDR line
- Restricted airflow extending or stalling cycles — First, and the cheapest to rule out. An automatic cycle ends when the load is dry, so a machine that cannot dry never reaches the end and runs on indefinitely.
- Moisture sensor bars coated with residue — Next most likely on these models. It ranks first because it explains the commonest cycle complaint of all — a cycle that ends in minutes with a wet load — and it is cured with a cloth.
- Thermal protection opening mid-cycle — Third — worth checking once the two above are clean. It ranks here because the machine is telling you something is wrong upstream and the device is doing its job.
Check in this order, and why
- Clear the lint screen and check the duct to outside — A machine that cannot exhaust cannot finish an automatic cycle. Disconnect the hose briefly and feel the airflow at the outlet.
- Wipe the sensor bars inside the drum with a cloth — They are the two metal strips near the lint screen opening. Clean them with a little vinegar or detergent, rinse, and run the same load again.
- Note whether it restarts after cooling down — A machine that stops mid-cycle and runs again after an hour is tripping a protector, which puts the fault upstream in heat or drag.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off. Never run the machine with the drum panel removed to observe a fault, and clear lint from the cabinet while you are inside it: lint against a heater is how dryer fires start.

When to call a technician
The owner line on the USDR line runs to the sensor bars, the lint path and the load itself. Past that, thermistors, protectors and control boards all need a meter and the cabinet open. Note which programmes fail before you call — that pattern is worth more to a technician than any description of the symptom.
