Professional Repair Guide

What is this symptom?

Is your Smeg oven making unusual noises during operation? Common sounds include loud fan noise, rattling, or humming.

Important Tips for Smeg Models

Smeg ovens may run cooling fans even after use to maintain safe temperatures; this can be mistaken for a fault if unfamiliar with normal operation.

Possible Causes

Cooling/circulation fan noise (normal or excessive)

How to Identify: Noise correlates with fan operation when oven on or cooling down; humming/whirring from back or top area

Part: Cooling fan / convection fan motor

Worn fan motor bearings or loose fan blade

How to Identify: Grinding, screeching, or wobble when fan spins; persistent noise beyond normal fan hum

Part: Fan motor bearings / fan blade

Loose interior components or racks

How to Identify: Rattling that changes when oven vibrates; noise disappears when rack position changed or screws tightened

Part: Interior screws, racks, panels

Faulty thermostat causing fan to run continuously

How to Identify: Fan continues running long after oven has cooled with no temperature gradient

Part: Thermostat / thermal control
