What C-d0 Means

C-d0 (and C-d1/C-d2) means a door or key error — the microwave senses the door or a button as stuck.

Common Causes

1
Door switch fault

A door interlock switch is mis-reading.

2
Stuck key

A control-panel button is stuck.

How to Fix It

  1. Open and firmly close the door; make sure nothing blocks it.
  2. Unplug for a minute; if C-d0 persists, the door switches or keypad need service.
