Samsung Dryer dF code: Door switch error
The dryer is getting an incorrect signal from its door switch. Unlike a simple door-open code, this usually means the switch or its wiring is at fault.
Most common causes
- Faulty door switch
- Loose or damaged door switch wiring
- Damaged door latch pressing the switch incorrectly
What you can safely check yourself
- Close the door firmly and make sure nothing is caught in it.
- Power the dryer off for a minute, then back on and restart.
Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
