Dry time ran out
The cycle ran to its maximum time and the load never read dry. Air that cannot get out, a heater that is not heating, or a moisture sensor coated in film.
- The lint screen is clean and the screen slot under it is clear — reach in with a vacuum crevice tool.
- The vent hose behind the dryer is not crushed, and the flap at the outside wall opens when the dryer runs.
- An electric model: both breakers are on. A gas model: the gas valve behind the dryer is open and the other gas appliances light.
- The two metal moisture-sensor bars inside the drum opening are wiped with a little rubbing alcohol — dryer-sheet film makes them read dry when the load is not.
Clean the lint path and the vent and run a Timed Dry; the code clears when a load finishes on time. Good airflow with no heat at all is the heating element or the gas igniter — a part, and on a machine under warranty a warranty call.
A dryer that blows cold with the vent clear and both breakers on has a heating element, a thermal cutoff or an igniter that has failed — a technician's part.
