The oven cannot confirm that its door lock is working. It most often shows up before or after a Self Clean cycle, when the motorized lock fails to lock or unlock the door.

Likely causes

Listed from most to least common.

  1. Door lock motor stuck after a Self Clean cycle
  2. Debris or a bent rack blocking the door from closing fully
  3. Faulty door lock motor or switch assembly
  4. Loose wiring to the lock
  5. Control board fault

How to fix the C-d1 code

Unplug the oven or switch it off at the breaker before removing any panel or filter.

  1. Step 1: Let the oven cool completely

    If the code appeared during or after Self Clean, wait until the oven is fully cool. The door stays locked while the oven is hot, and that is normal.

  2. Step 2: Turn the oven off and on

    Press Off or Power to turn the oven off, then turn it back on and see if the code clears.

  3. Step 3: Reset at the breaker

    If the code returns, switch off the circuit breaker for the range for at least 30 seconds, then turn it back on. The lock often resets itself after power returns.

  4. Step 4: Check the door closes fully

    Once the door is unlocked, look for racks, foil or food blocking it. Close it gently and make sure it sits flat against the oven.

Parts that may need replacing

Check your model number on the label inside the door or on the back before ordering.

When to call a technician

Call a technician if the code returns after a breaker reset, or if the door stays locked when the oven is cold. Do not try to force the door or bypass the lock.

A typical repair for this code costs $150–$350 in the US, including parts and labor. Prices vary by area and model.

Models this applies to

  • Electric, gas and induction ranges (NE, NX and NSI series)
  • Flex Duo ranges with oven divider
  • Slide-in and freestanding ranges
  • Single and double wall ovens (NV series)

Codes can differ slightly between models. Your owner's manual is the final word and is available from Samsung support.

Common questions

›How do I unlock my Samsung oven door after Self Clean?

Let the oven cool fully, then turn it off and on. If it stays locked, switch off the breaker for at least 30 seconds and turn it back on.

›Can I still cook with a C-d1 code?

Sometimes the oven bakes normally once the door unlocks, but avoid Self Clean until a technician checks the lock.
