How to Fix / Troubleshooting

Safety first: Unplug the microwave before any disassembly.

Basic checks:

  • Open and firmly close the door; listen for distinct clicks.
  • Try multiple programs and power levels to see if any start.
  • Check if the child lock is active (often indicated by a key symbol); disable according to the manual.

Keypad and door switch checks (experienced users):

  • Remove the control panel trim to access the keypad ribbon cable; reseat the cable on the control board.
  • Test the START button function using the service mode if available in the Candy manual.
  • Inspect and test door interlock switches for proper operation with a multimeter.

Repair: Replace the membrane keypad or door switch kit if found faulty. Reassemble carefully to maintain door alignment and shielding.
