Possible Causes
Stuck relay on control board, Burnt relay contacts, Cold solder joints on PCB, Overheated control board area
How to Fix / Troubleshooting
Safety first: Unplug the microwave before any inspection.
- Observe behavior: Note whether the interior light, fan, or turntable run when they should be off, or fail to run when commanded. This helps identify which relay is affected.
- Power reset: Disconnect power for 10–15 minutes, then reconnect and test. If E17 returns, internal relay issues are likely.
- Professional repair: The control board must be removed and inspected by a technician. Burnt or stuck relays and cracked solder joints should be replaced or re-soldered, or the entire board replaced.
Warning: Do not continue using the microwave if components run unexpectedly; this can be a fire or shock hazard.
