How to Fix / Troubleshooting
Safety first: Isolate power and allow the oven to cool before removing panels.
- 1. Remove rear panel: Inside the oven, remove the screws holding the fan cover and inspect the fan blade for damage or debris.
- 2. Tighten fan nut: If the fan blade is loose on the shaft, carefully tighten the central nut (usually reverse thread on some models).
- 3. Check for debris: Remove any trapped foil, screws, or food residues.
- 4. Assess motor bearings: Spin the fan by hand. If it feels rough or wobbly, the motor bearings are worn and the motor should be replaced.
- 5. Replace fan motor if needed: Access from the rear, remove mounting screws, and fit a new Rangemaster fan motor.
