How to Fix / Troubleshooting
Safety first: Disconnect power before touching any moving parts.
Step-by-step checks:
- 1. Identify noise source: Run the oven briefly and listen from front, sides, and rear to locate the area of noise (qualified person only).
- 2. Check convection fan: Remove the rear inner panel and spin the fan blade. Tighten the central nut and replace the fan motor if bearings are noisy or rough.
- 3. Inspect cooling fan: Remove the top cover and check the tangential fan for loose mounting screws or contact with the housing.
- 4. Tighten panels: Tighten any loose screws on side panels, rear cover, and internal baffles.
Warning: Do not attempt to bend fan blades excessively; this can unbalance the fan and increase noise.
