Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave and allow it to cool before inspection.
- Step 1 – Check installation clearances: Ensure the microwave has the minimum clearances specified by Indesit on all sides and top. Built‑in models must be installed with the correct trim kit.
- Step 2 – Clean vents: Vacuum and wipe all external vents to remove dust and grease buildup.
- Step 3 – Verify fan operation: During a cooking cycle, listen for the cooling fan. If it is not running, the fan motor or its control circuit may be faulty.
- Step 4 – Internal cleaning (advanced): Remove the outer cabinet and gently clean dust from the fan blades and air channels.
- Step 5 – Replace faulty fan: If the fan motor is not operating or is noisy and slow, replace it with a genuine Indesit cooling fan motor.
Note: Prolonged overheating can damage internal components and shorten the life of the microwave.
