Whirlpool Dryer Error Code dC

The dC code stands for Door Circuit Failure. It means the control board detected an invalid signal from the door sense circuit for more than 256 milliseconds. This could be due to a loose wire terminal, an open circuit in the wiring harness, or a faulty door switch. The dryer will not operate normally until the door circuit issue is resolved.

A reset may temporarily clear the code, but it will return if the underlying problem in the door sense circuit has not been fixed. Resetting is useful to confirm whether the fault is intermittent, but it is not a repair. The circuit fault must be identified and corrected to permanently resolve the dC error.

If the fix is just reseating a loose connector or cleaning corroded terminals, the repair may cost nothing beyond your time. Replacing a door switch typically involves a parts cost in the range of $15 to $50, plus labor if a technician is involved. If the control board needs replacement, costs can range from $100 to $300 or more depending on the model and service fees.

In many cases, yes. Start by checking for loose or open wire terminals in the Door Sense circuit, as these are the most common cause and require no parts to fix. If the wiring checks out, you can test the door switch for continuity using a multimeter and replace it if it has failed. More complex issues involving the control board are best handled by an experienced technician.

It is not recommended. The dC code means the dryer cannot confirm the door is properly closed, and the safety circuit exists to prevent the drum from running with the door open. Operating the dryer in this condition could be a safety hazard. Address the door circuit fault before resuming use.
