Samsung Dryer Not Turning Off: Check Wrinkle Prevent before Calling for Service

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop the dryer immediately if there is visible smoke, gas odor, burning or electrical smell, a spark, abnormal heat, damaged wiring, or a repeated breaker trip. Do not open the door to investigate a fire, operate switches in a gas-smell area, or start another cycle.

   Expected result: The dryer is quiet and free of odor, smoke, sparks, overheating, and electrical damage, or one of those hazards is present.

   Next step: For gas odor or smoke, clear the area and contact emergency help from outside. For burning or electrical smell without an active emergency, leave the dryer off and arrange qualified service.

   Why this matters

   Why: An active fire, gas, or electrical hazard is an emergency or service boundary, not a normal shutoff symptom.

2. Check 2

   Without reaching into the machine, read the display and observe from a safe position whether only the panel or drum light is on, the drum is tumbling without heat, the drum is still heating, or the dryer is completely unresponsive to Power.

   Expected result: The panel or light remains on but the drum is stopped; the drum tumbles intermittently; the drum runs continuously; heat persists; or the controls do not respond.

   Next step: Follow the normal-post-cycle branch for light or no-heat tumbling. If motion, heat, or control failure persists, stop using the dryer and continue only with the safe control and power checks below.

   Why this matters

   Why: A light or panel can be normal after shutdown, and Wrinkle Prevent tumbles without heat. Continuous tumbling, continued heat, or no control response is not explained by a light alone.

3. Check 3

   If the cycle has ended and the drum turns without heat, check whether Wrinkle Prevent is enabled and open the door only if the dryer is in a normal safe state and the manual permits it. Do not reach into a moving drum; use the door as the normal stop signal for the post-cycle function.

   Expected result: The display shows END or Wrinkle Prevent and the drum stops when the door is opened, or the drum keeps running or heating after the door is opened or after the post-cycle state should end.

   Next step: If it stops normally, remove the load or disable Wrinkle Prevent using the model's controls. If it does not stop, keep the dryer out of service and request qualified diagnosis.

   Why this matters

   Why: Wrinkle Prevent is a normal no-heat post-cycle behavior on applicable models. Failure to stop through the normal door or control path points to a door switch, motor control, or other fault.

4. Check 4

   Press Power once as the exact model manual describes and check the display for Child Lock, a delay, remote-control state, or an error. If Child Lock is shown, use the model's documented control combination to turn it off; do not guess or force buttons, and do not treat a locked panel as a mechanical failure until the icon and manual are checked.

   Expected result: Child Lock or another control state explains the ignored buttons, Power responds normally, or the panel remains unresponsive and the drum or heat continues.

   Next step: If the control state was the cause, stop the cycle normally and monitor it. If Power still cannot stop motion or heat, do not bypass the controls; proceed to one safe reset or service.

   Why this matters

   Why: Child Lock can disable most controls, while cycle-specific options vary by model. A panel that remains unresponsive after the documented lock state is cleared suggests a control or power fault.

5. Check 5

   From outside the dryer, determine whether the drum is only tumbling intermittently with no heat or is running continuously and producing heat after the cycle should have ended. Do not touch the drum, vent, heater area, motor, or internal wiring to make this determination.

   Expected result: Only no-heat intermittent tumbling occurs, the drum runs continuously, heat continues, the drum will not stop when the door is opened, or the dryer stops but the panel remains lit.

   Next step: Use the normal post-cycle controls only for the first case. For continuous motion or heat, keep the dryer off and arrange service; for a panel light alone, follow the model's normal shutdown behavior.

   Why this matters

   Why: No-heat intermittent movement is consistent with Wrinkle Prevent. Continuous motion, continued heat, or failure of the door stop signal is a service symptom; a lit panel by itself may be normal on some models.

6. Check 6

   Only when there is no gas odor, smoke, burning smell, abnormal heat, water, visible damage, or repeated trip, and the model guidance permits it, isolate the dryer using the normal household disconnect once, restore power, and press Power. Do not use a reset to keep operating a dryer that immediately resumes continuous motion or heat.

   Expected result: The dryer returns to a normal idle state, or it resumes running, heating, ignores Power, shows the same error, or trips protection again.

   Next step: If the symptom returns, leave the dryer out of service and request qualified Samsung appliance service. If a breaker trips or an odor or smoke appears, stop and use the urgent safety path.

   Why this matters

   Why: A single reset may clear a transient control state. A recurring run or heat condition indicates a persistent control, motor, heater, door, or wiring fault and needs professional diagnosis.
