Ten minutes into the cycle, the dryer just… stops. You restart it; it runs a while and quits again. A mid-cycle shutdown is almost never random — the machine is protecting itself from something, and the pattern of when it quits names the something.
Quits after a consistent 5–15 minutes, restarts after a rest: overheating
This is the classic. Heat builds faster than airflow can carry it out; a thermal safety opens; the machine cools; it will run again — briefly. The suspects behind the trip: a vent run choked with lint (the leading cause, and our dry-climate lint travels deep), a blower wheel packed or cracked, a cycling thermostat drifting out of spec, or on older machines a motor whose own thermal protector is opening as bearings drag. The tell that separates airflow from parts: go feel the exhaust at the outside vent hood mid-cycle — a limp, lukewarm breeze convicts the duct before a single panel comes off.
Quits early with clothes still damp, no restart drama: the sensor's honest opinion
Sensor-dry cycles end when the moisture bars inside the drum read "dry" — and bars filmed over by years of dryer sheets hallucinate dryness in minutes. Wipe the two metal strips inside the drum with rubbing alcohol; it's a free fix and it closes a surprising share of these calls. (A too-small load tumbling past the bars without touching them produces the same early quit — add a couple of towels.)
Quits at random moments, sometimes won't restart at all: electrical
A door switch failing intermittently (the drum light flickers when you press the door), a worn Start switch, a half-failing thermal fuse, or on electronic models a board relay heating up and letting go — these produce the maddening no-pattern version. This tier is meter territory, and honestly faster for us to find than for anyone to guess at.
Why not to just keep restarting
Every overheat trip is the machine aging in fast-forward, and the underlying restriction is the same one implicated in dryer fires — the safety that keeps quitting is doing exactly its job. One visit: airflow measured at the exhaust, thermostats and switches metered, blower opened if the numbers say so, fixed quote before any part is swapped. Same-day across Boise, Meridian and the rest of the valley, because laundry doesn't pause for diagnostics.
