Quick answer
tC7 is a temperature sensor error on Samsung heat-pump dryers.
Model compatibility: Samsung reuses codes across series and model years, so tC7 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Temperature sensor error.
tC7 is listed for Samsung heat-pump dryers as a temperature sensor error. The Samsung Russia list describes it as the temperature sensor not working correctly.
What to do
Samsung gives no owner steps for tC7, so the sensor is a matter for a technician. Unplug the dryer if you need to leave it unused until it is looked at.
