How to Fix / Troubleshooting
Safety: Unplug before tightening or inspecting internal parts.
- Step 1 – Isolate the noise: Run the microwave briefly with the turntable and roller ring removed (with a cup of water on the floor). If noise stops, the issue is with the turntable system.
- Step 2 – Check roller ring and tray: Inspect for flat spots on wheels, cracks, or debris. Replace damaged parts.
- Step 3 – Inspect cooling fan: Remove the outer cabinet and check the fan blades for contact with wiring or panels. Tighten fan mounting screws and reposition any cables.
- Step 4 – Tighten hardware: Check and tighten loose screws on the magnetron, transformer, and cabinet.
