What C-d0 / C-d1 / C-d2 means

C-d0, C-d1, and C-d2 appear on Samsung microwaves and are listed as a door or key error. The microwave has a problem with the door switches or with a panel key, and it stops and shows the code. The listing covers Samsung microwaves in general, not one model. You may see the code when you close the door or press Start, and the microwave will not begin cooking.

Common causes of C-d0 / C-d1 / C-d2

  • A door that does not close fully or a latch that does not catch
  • A door switch not reading closed
  • A panel key that is stuck or reading pressed
✓ One safe check you can try

1. Unplug the microwave or switch off its breaker. 2. Open the door and check that nothing is caught in the seal or latch, then close it firmly. 3. Touch the keys lightly to see if one is stuck. 4. Wait 60 seconds, then restore power. 5. If the code shows again, leave the microwave off and request service.

! Why to stop there
  • The code covers both the door and the keys, so we test each to see which one the control is not accepting.
  • We check the door latch, the switches, and the panel keys.
  • We give you a written price first, and our repair has a 30-day workmanship warranty.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

C-d0 / C-d1 / C-d2C-d0 / C-d1 / C-d2 questions
Is C-d0 about the door or about the keys?

It is listed as a door or key error. The control is not getting a normal signal from the door switches or from a panel key.

Why does it show a door code with the door closed?

The latch or a switch may not register closed, or a key may be reading as pressed. Debris and wear can cause both, and a test finds which.

Is it safe to use a microwave with a door error?

The door switches keep the microwave from running with the door open, so we do not want them bypassed. Leave it off and have the door system checked.
