Start inside the drum
If the machine stops after a few minutes on an automatic cycle but runs the full time on a timed one, the moisture sensor is your answer and the fix is a cloth. If the console ignores selections or responds to the wrong pad, that is a membrane problem. Those two account for most control complaints on this cabinet.
What you notice
- An automatic cycle ends after a few minutes with the load still wet — The machine believes it is finished, which is a sensing statement rather than a fault.
- A timed cycle runs the full duration normally — The strongest possible confirmation that the machine itself is healthy and the sensing is not.
- A pad has to be pressed repeatedly or in a particular spot — A console membrane symptom, and it is distinct from anything to do with sensing.
- The display shows a code and the drum stops mid-cycle — A genuine sensed condition, most often airflow or temperature, being reported.
- NEAR MISS: the machine tumbles the full cycle and stays cold — That is a heating complaint with its own page and a different order.
Ranked for this cabinet
- A film on the moisture sensor strips — First by a long way. Softener and dryer-sheet residue build up invisibly, and the machine has no way to distinguish a coated strip from a dry load.
- The console membrane or a stuck pad — Second. It explains unresponsive or wrong-pad behaviour and nothing else, so its symptom set identifies it.
- An airflow or temperature condition being reported — Third. Real, and it needs the duct cleared rather than the console touched, which is why it sits here.
- The control board — Last. It reports the three above, and on this cabinet it is replaced far more often than it fails.
Two cycles tell you almost everything
- Run a timed cycle and then an automatic one with similar loads — If timed works and automatic does not, the sensor is the answer and you are finished diagnosing.
- Wipe the sensor strips inside the drum — Top cause and a two-minute job with a cloth and a little rubbing alcohol.
- Press every pad on the console and note which respond — Second cause, separated cleanly by which pads misbehave.
- Clear the lint path before blaming any electronics — Airflow underlies the third cause and half of everything else a dryer reports.
Owner steps
- Find the two metal strips inside the drum, usually near the lint screen opening — They look like a pair of curved bars. Their condition is the whole of the top cause.
Tools: flashlightAbout 5 min
- Wipe them with a cloth and a little rubbing alcohol until they are bright — Residue is invisible when dry. Clean until the cloth stops picking anything up.
Tools: cloth, rubbing alcoholAbout 10 min
- Run an automatic cycle with a damp towel and see whether it now runs on — A direct before-and-after test of the repair you just made, and it costs one towel.
About 25 min
- Clean the lint screen and clear the duct behind the machine — It addresses the third cause and improves every cycle regardless.
Tools: vacuum, duct brushAbout 25 min
- STOP before the console is opened to reach the membrane — There are live terminals behind it, and that is the boundary for owner work.
Before anything opens
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Use only a small amount of alcohol on a cloth inside the drum and let it evaporate fully before running the machine. On a gas cabinet, if you smell gas, do not switch anything on or off, leave the building, and call the gas utility or your local emergency number from outside.
When it becomes a call
Call once the sensor strips are clean, the duct is clear, and an automatic cycle still ends early, because the next checks are meter work on the sensing circuit. Call sooner if the console is discoloured, if a pad feels hot, or if the machine trips its breaker. Be ready to say whether a timed cycle behaves normally: it is the single most useful sentence you can offer on this fault.

Scope of this page
Written for the Whirlpool dryer class, not one family. Sensor strip positions, console layouts and part references differ between cabinets and belong on the family page for your machine. Where that page exists it is the more specific answer; this one is written from behaviour that is common to all of them.
