Dryer Won't Shut Off in St. Johns
The cycle should have ended an hour ago — the dryer is still tumbling (or still heating). A dryer that won't stop wastes energy at best and cooks clothes and itself at worst.

What's going on with your dryer
Sort the complaint first: does it tumble forever without heat, heat without stopping, or simply never advance its timer? Each is a different system — the timer or control that ends cycles, the heating circuit that ignores commands, or the moisture sensor that never declares the load dry. A dryer found still running after a forgotten load is the common discovery story, and the pattern of what's still on (drum? heat? both?) is the map.
St. Johns sits about 18 miles from Downtown Jacksonville, part of the wider metro — pros based across the city cover it on their regular rounds.
How urgent is it? Heat-that-won't-stop is urgent — unplug and call. Tumble-forever on timed cycles is an energy and wear problem worth a this-week visit.
What causes dryer won't shut off
Every one of these is found by testing, not guessing — the diagnostic confirms which one you have before any part is quoted.
What you can safely check yourself
- Determine what's still on: drum only, heat only, or both — and whether the timer display is advancing at all.
- Try timed dry instead of auto: if timed cycles end normally, your moisture sensor system is the story.
- Clean the moisture sensor bars inside the drum (two metal strips near the lint filter) with a cloth and a little rubbing alcohol — film on them is the classic auto-cycle liar.
- If the heat stays on with the dryer 'off,' unplug it and call promptly — a machine heating uncommanded is not a wait-and-see appliance.
What a technician checks
Cycle control is tested at its outputs: timer advance verified, board relays checked for welded contacts, element tested for grounds, moisture-sensor circuit measured with wet and dry loads simulated. The fault is found in the system that's actually misbehaving — timer, sensor, or power circuit — rather than the system that merely looks guilty.
Parts most often involved in this repair: timers, control boards and relays, moisture sensors, heating elements. Each is identified against your exact model number — no universal substitutes.

Dryer Won't Shut Off in St. Johns — questions
Why does my dryer run for hours on auto dry?
Because the moisture sensor never gets to declare the load dry — usually because its bars are filmed with softener residue, sometimes because the sensor circuit has failed. Timed dry bypasses the liar.
Why is my dryer still hot after the cycle ended?
Residual heat is normal for a few minutes. A dryer actively heating after 'off' suggests a grounded element or welded relay — that's an unplug-and-call, not a quirk.
Can a dryer really run all night?
Yes — a failed timer or control won't stop it, and it'll tumble (and possibly heat) until it's stopped manually or something else fails. Found one running in the morning? Get it checked before its next load.
