Possible Causes
Stuck or burned relay contacts, Failed triac or transistor driver, Cold solder joints on PCB, Overheated control board
How to Fix / Troubleshooting
Safety: Unplug the microwave before any internal inspection.
Steps:
- 1. Observe symptoms: Note which functions fail (light, fan, turntable, heater). This helps identify which relay or driver is affected.
- 2. Power reset: Disconnect power for 10 minutes and retest. Sometimes a relay can reset after cooling.
- 3. PCB inspection (DIYers): Remove the control board and inspect the solder side for cracked joints around relays and high-current components. Look for darkened areas indicating overheating.
Resolution: Replace the main control PCB or have a qualified electronics technician replace the faulty relay/driver using the correct IKEA-compatible parts.
