Quick Answer: Why Your Maytag Dryer Won't Stop#
Most likely: it is not actually broken — the Wrinkle Prevent feature keeps tumbling with no heat for up to 150 minutes after the cycle ends to keep clothes from setting, and that is easily mistaken for a dryer that won't stop. When it is a genuine fault, dirty Advanced Moisture Sensing bars are the usual cause, because the four sensor bars (Maytag uses four versus two on a base Whirlpool) read residue film as damp fabric and keep the cycle running. Less often, a stuck control-board relay leaves the motor or heat energized after the cycle should end. Rule out the feature first, then clean the sensors, then look at the board.
Likely Causes at a Glance#
| Cause | Likelihood | What to check |
|---|---|---|
| Wrinkle Prevent / extended tumble mistaken for a fault | Most likely (a feature) | periodic no-heat tumble runs up to 150 minutes after the cycle — normal |
| Dirty Advanced Moisture Sensing bars | Common (~10%) | film on the four bars reads as wet fabric and stretches the cycle |
| Control board / Extra Power relay stuck | Occasional (~9%) | heat or the motor stays on past cycle end; unplug if it will not stop |
| Door switch not ending tumble | Occasional | some models rely on the door switch to halt the drum |

Walking Through the Diagnosis#
Start by confirming what you are actually seeing. Maytag's Wrinkle Prevent tumbles the drum periodically with no heat for up to 150 minutes after a cycle finishes, and Extra Power adds heat and extended tumble to a cycle — both are normal and both look like a dryer that refuses to stop. Open the door mid-tumble; if the air is cool and the clothes are dry, it is the feature, and you can turn it off in the cycle settings.
If it is genuinely over-running, clean the moisture sensors. The Advanced Moisture Sensing system uses four metal bars inside the drum (near the lint-screen opening) that gauge dryness by electrical resistance; a coating of dryer-sheet or fabric-softener film makes them read "wet" so the dryer keeps going. Wipe all four with fine 220-grit sandpaper followed by rubbing alcohol on a lint-free cloth. If it still runs long after cleaning, the sensor circuit or a stuck relay on the control board may be at fault — a board that keeps the heat or motor energized after the cycle, or leaves it running until you unplug the dryer, points at a welded Extra Power or heat relay. Maytag shares the Whirlpool F#E# diagnostic system, and F1-series codes indicate a board failure.
Because Maytag runs the same Whirlpool platform, keep the wider picture in mind: the exhaust-housing thermal fuse is the single most common failure across these dryers (about a quarter of service calls) and always traces to restricted airflow, so a clean vent — the lint screen every load, the full duct annually, max 25 feet less five feet per elbow — protects the whole machine. Before paying for any motor work, check the 10-year limited parts warranty on the drive motor and drum.
Safety note: unplug or switch off the breaker before service (240-volt for electric MED models, 120-volt for gas MGD models), close the gas valve on gas units, and never bypass a thermal protection device.
Repair or Replace? The Short Version#
Most "won't stop" complaints cost nothing to resolve — it is a feature or a sensor wipe — and even a control board is a targeted repair well under any replacement threshold on a dryer built to commercial-grade specs. On a unit under eight to ten years old, repair is the clear choice. If a suspected board relay needs metering, our technicians carry the parts and confirm it in one visit — schedule a visit.

Frequently Asked Questions#
Why does my Maytag dryer keep tumbling after the cycle ends?#
Most often it is the Wrinkle Prevent feature, which tumbles with no heat for up to 150 minutes to stop clothes creasing. Open the door — cool air and dry clothes confirm it is the feature, which you can disable in the cycle settings.
Could dirty sensors make my dryer run too long?#
Yes — the four Advanced Moisture Sensing bars read residue film as damp fabric, so the dryer keeps running to "finish." Clean all four with 220-grit sandpaper and rubbing alcohol to restore accurate readings.
The heat or motor stays on until I unplug it — what's wrong?#
That points to a welded relay on the control board keeping the circuit energized past cycle end. Unplug the dryer to stop it, and have the board's heat or Extra Power relay tested.
Is a Maytag dryer that won't stop worth repairing?#
Usually yes, especially under eight to ten years old, since the common causes are free or inexpensive. Check the 10-year parts warranty on the motor and drum before authorizing any major part.
