Samsung Range Error Code C-d

C-d means the range has detected a key on the control panel keypad that has been continuously pressed for one minute or more. The control board treats this sustained contact as a shorted key fault. This can come from a physically damaged membrane, liquid contamination, or a faulty ribbon harness connection. The range triggers this code to flag the abnormal input condition.

A power reset by unplugging the range or turning off the circuit breaker for a few minutes may temporarily clear the code, but it will return if the underlying fault is not repaired. If the membrane, harness, or PCB has an actual short circuit, the code will reappear once the range is powered back on. A reset alone is not a fix, only a temporary diagnostic step.

Repair costs vary depending on which component has failed. A replacement membrane keypad assembly typically ranges from $30 to $100 for the part alone, depending on the specific model. If a technician is needed, labor charges generally add $80 to $200. PCB replacement is more expensive, with parts ranging from $100 to $300 or more, plus labor.

Some cases can be addressed by a knowledgeable DIYer. Start by disconnecting power, then reseating the membrane wire harness at the PCB connection. If the harness was loose, this may clear the fault. If the membrane itself is shorted or contaminated, replacing the membrane keypad assembly is the typical repair, which requires disassembling the control panel. PCB faults are more complex and may be better handled by a technician.

It is not recommended to continue using the range while this code is active. A shorted key condition means the control board may be receiving unintended input signals, which could interfere with normal operation or cause unintended functions to activate. Disconnect power to the range until the fault has been properly diagnosed and repaired.
