Error code3C, 3E
ApplianceDryer
Samsung describes 3C, and its twin 3E, in three ways. Its US list says motor error. The UK list asks for the inverter motor to be checked for operation. For heat-pump models the wording becomes motor rotation error. No model range is attached.
First things to do
Wait 2-3 minutes with the power off, then power up and start the cycle over.
If it halts again, examine the installation. For heat-pump models Samsung names weak or fluctuating supply voltage, an extension lead, surge protector or adapter between wall and dryer, and an overfilled drum.
Look in the user manual for the steps that fit your model.
A faulty motor or motor speed sensor is also on the heat-pump list of causes; testing it falls to a technician, not the owner. When the code returns, Samsung’s answer is to request service.
AC6, AE6: a communication fault between two boards.
Samsung dryer repair in San Francisco
When 3C keeps stopping a Samsung dryer in San Francisco or elsewhere in the Bay Area, Samsung dryer repair is the page to start from, and (415) 969-6153 is the number. Have the code, the model number and the restart attempts you made ready to share.
Model compatibility: Samsung reuses codes across series and model years, so 3C, 3E may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
