What the C-d1 error code actually means

Your Samsung range is displaying C-d1 because it cannot confirm that the oven door is locking or unlocking properly, which is required for the self-clean cycle to operate safely. This is usually caused by a loose wire connection or a problem with the door lock motor or switch. The oven will not allow a self-clean cycle to run until this issue is resolved.

Questions people ask about C-d1

What does C-d1 mean on a Samsung range?
C-d1 is a door locking information error on Samsung ranges, indicating that the door lock mechanism is not functioning properly. The control board expects to receive signals from the door lock switch and motor confirming that the oven door has locked or unlocked, but those signals are missing or incorrect. This error most commonly appears in relation to the self-clean cycle, which requires a confirmed door lock before it can operate.
Is it safe to use my Samsung range while the C-d1 error is active?
Standard baking and cooking functions may still be available while C-d1 is displayed, but the self-clean cycle cannot and should not be run until the door lock issue is resolved. Operating the self-clean cycle requires a properly secured door latch, and attempting to bypass or ignore this error during a self-clean cycle creates a safety risk. Resolve the door lock fault before using any high-temperature oven functions.
How much does it cost to repair a Samsung range C-d1 error?
If the issue is only a loose or disconnected harness, there may be no parts cost at all, just the time for diagnosis. Replacing a door lock motor or switch typically costs between $40 and $120 for the part, depending on the specific model. If a professional repair technician is needed, total repair costs including labor generally range from $100 to $250, with control board replacement on the higher end of that spectrum.
Will resetting the range clear the C-d1 error?
Disconnecting power to the range for several minutes may temporarily clear the C-d1 code, but it will return if the underlying problem with the door lock assembly or wiring is not addressed. A reset is useful for confirming whether the error is intermittent or persistent, but it is not a permanent fix. The door lock harness, switch, and motor should all be inspected before relying on a reset.
How do I fix the C-d1 error on a Samsung range?
Start by disconnecting power to the range, then remove the back cover and inspect the wiring harness connected to the door lock switch and motor, checking for loose, corroded, or damaged connectors. Reconnect any loose connectors and restore power to see if the error clears. If the wiring is intact, the door lock switch or motor may need to be tested for continuity and replaced if faulty. Clearing debris from the latch track is also worth checking before replacing any parts.
