Microwave convection mode does not reach or maintain the set temperature; food takes much longer to bake.

Safety first: Unplug the microwave and allow it to cool before inspection.

• Step 1 – Preheat check: Use an oven thermometer to verify the actual temperature reached in convection mode compared to the set value.
• Step 2 – Check fan operation: Ensure the convection fan runs continuously during convection cooking. If not, see convection fan fault guidance.
• Step 3 – Inspect heater: Look at the rear or top convection heater for visible damage or breaks.
• Step 4 – Sensor and seal: Check the cavity temperature sensor and door seal for damage that could affect temperature control.
• Step 5 – Replace faulty components: Replace the convection heater, fan motor, sensor, or door seal as required using genuine Indesit parts.

Tip: Avoid opening the door frequently during convection cooking, as this can significantly drop the temperature.
