How to Fix / Troubleshooting
Safety: Unplug before removing covers. Avoid touching HV components.
Steps:
- 1. Isolate noise source: Listen carefully to determine if the noise comes from the bottom (turntable), back (fan), or top (magnetron/transformer).
- 2. Check turntable system: Remove the tray and roller ring, then run briefly with a cup of water. If the noise disappears, the issue is with the tray, ring, or coupler.
- 3. Inspect fan (DIYers): Remove the outer cover and check the cooling fan for debris or bent blades. Clean and straighten as needed.
- 4. Tighten hardware: Carefully tighten mounting screws on the magnetron, transformer, and fan bracket.
Resolution: Replace noisy fan or turntable motors with IKEA-compatible parts. If the magnetron itself is noisy, it may need replacement.
