Air fryers make some noise — it's a powerful fan, after all — but it's a hum rather than a roar. Here's what's normal, what makes the sound, and what to do if yours seems too loud.
Key takeaways
Q: How noisy are air fryers?
A: Most run at a steady fan hum of roughly 50–65 decibels — about the level of a kitchen extractor fan or a quiet conversation.
Q: What makes the noise?
A: The fan that circulates the hot air, plus the thermostat clicking on and off.
What's normal
A constant whirring fan noise is completely normal — it's how the air fryer moves hot air around the food. You may also hear gentle clicks as the thermostat cycles, and some rattling from food being blown about (lightweight items especially). None of this is a problem.
If yours is too loud
- Check it's level — a wobbling unit on an uneven surface rattles.
- Listen for grinding or screeching — that can mean a failing fan bearing; have it checked.
- Secure light food that's flapping against the element.
- Compare models — if buying, some list their decibel rating; basket models are often quieter than larger ovens.
