LG Dryer Error Code dC

The dC code on an LG dryer means the control board has detected that the door is open or is not registering as properly closed during operation. The dryer will not run or will stop running when this condition is present. The code points to the door sensor unit and its wiring as the area to inspect.

The dC code means the dryer has detected an open door condition, and the appliance is designed to prevent operation under this fault to avoid running with the door open. Do not attempt to bypass the door switch to force the dryer to run. Resolve the underlying issue with the door sensor before using the dryer again.

If the fix is a loose wiring connection, there may be no parts cost involved, only the time to inspect and reseat the connector. Replacing a door sensor unit typically costs between $15 and $50 for the part, depending on the model. If a professional technician is needed, total repair costs including labor generally range from $75 to $175.

Start by firmly closing the door until the latch clicks, then restart the dryer. If the code returns, check the door sensor unit for loose wire connections and reseat any connectors. If the sensor unit is shorted or its internal contacts have failed, it will need to be replaced. Also inspect the door latch strike for wear or cracking that could prevent full engagement.

A reset may temporarily clear the code, but it will return if the root cause has not been addressed. If the door was simply ajar, closing it properly before restarting is all that is needed. If the sensor unit is faulty or a wiring connection is loose, the code will reappear as soon as the dryer attempts to run again.
