If your dryer keeps running after the cycle ends, check whether only the drum is tumbling briefly every few minutes. Wrinkle-prevent settings can do that by design. Turn that option off and test one ordinary cycle. If the drum, heat, or blower runs continuously, the display never reaches End, or the dryer will not stop with its controls, stop using it and arrange diagnosis. Do not leave an abnormal dryer running unattended.
Short bursts of tumbling after End Likely cause: Wrinkle Shield, Wrinkle Prevent, or another anti-crease option. Homeowner action: Check the option indicator and turn it off using the manual.
Drum runs continuously after End Likely cause: Timer, relay, motor circuit, or control fault. Homeowner action: Press Stop once; disconnect power if it ignores Stop.
Heat continues after the load is dry Likely cause: Control, temperature sensing, or heater-control fault. Homeowner action: Stop the dryer and book service; do not run another load.
Display time does not count down Likely cause: Sensor cycle, airflow restriction, or control problem. Homeowner action: Compare one timed cycle after cleaning the lint screen.
Dryer stops only when door opens Likely cause: Stuck switch, relay, timer, or control. Homeowner action: Do not use the door as a regular off switch; schedule diagnosis.
Dryer restarts on its own Likely cause: Wrinkle-prevent mode or electrical/control issue. Homeowner action: Note whether it is brief periodic tumbling or full heating restart.
DIY difficulty: Low for checking cycle options, observing intervals, cleaning the lint screen, and one timed comparison. Time: 20-40 minutes plus a short cycle. Tools: Manual, phone, flashlight. Safety risk: High if heat continues, the door interlock fails, or the dryer ignores Stop. Call a professional: Continuous operation, heating after End, abnormal heat or smell, repeated failure with wrinkle care off.
