Possible Causes

Defective power relay on control board, Faulty inverter module (on inverter models), Burnt solder joints on PCB, Control board power track damage

How to Fix / Troubleshooting

Safety warning: Internal power electronics carry mains and high voltage. Only attempt visual inspection if you are confident and always unplug first.

User-level steps:

  • Unplug the microwave for 5–10 minutes to allow the control board to reset, then plug back in and test.
  • If E07 appears immediately when starting microwave mode but other modes work, the issue is likely on the control board or inverter.

Visual inspection (experienced users):

  • Remove the outer cover after unplugging.
  • Locate the main control PCB and, if present, the separate inverter board.
  • Inspect for burnt components, cracked solder joints around relays, or discolored areas.
  • Do not attempt to repair the inverter at component level; these are usually replaced as a module.

Recommendation: Control board and inverter repairs require specialized knowledge and safety precautions. Contact a Candy service center for board-level diagnosis and replacement.
