Reference Model: DV22N

These error code explanations can help you diagnose a problem with your Samsung ventless heat pump dryer model DV22N


Code Meaning Possible Cause Possible Parts
tC Outlet thermistor (temperature sensor) resistance is too high or too low The outlet thermistor (temperature sensor) detects air temperature coming out of the condenser heat exchanger. Clean the lint filter and heat exchanger fins. If the problem continues, unplug the dryer and check the resistance of the thermistor. At room temperature, you should measure around 50K ohms of resistance through the thermistor. Replace the thermistor if resistance is off by more than 5K ohms Outlet thermistor
tC5 Compressor thermistor (temperature sensor) resistance is too high or too low The compressor thermistor senses temperature around the compressor inside the cabinet. To make sure that the compressor area is getting proper air flow, clean the lint filter and clean the heat exchanger fins. Make sure that the dryer is installed properly with proper clearance on the sides and back of the dryer. If these tips don't help, unplug the dryer and check the resistance of the compressor thermistor. At room temperature, you should measure around 50K ohms of resistance through the thermistor.

3C, 3C2, 3C3, 3C4, 3C5, 3C6, 3C7 or 3C8 Drive motor failure Unplug the washer and check the wire harness connections between the drive motor inverter board and the drive motor. Reconnect any loose wiring connections. Check the belt and all drive components. Replace any worn drive components. If all drive components and wiring connections are okay, you may need to replace the drive motor inverter control board Drive motor, drive components, belt, inverter control board
9C1 or 9C2 Power supply failure The control board detects under-voltage or over-voltage. Unplug the dryer for 3 minutes to reset the control board. If the code returns after you restore power to the dryer, check the voltage supply. If the voltage supply is normal, you may need to replace the electronic control board Main electronic control board
AC4 Communication error between the main electronic control board and the Wi-Fi control board Unplug the dryer for 3 minutes to reset the control board.
