Why is your air fryer making a loud grinding or rattling noise?

You’re enjoying the sizzle of your dinner when suddenly, your air fryer starts making a sound like it’s trying to take off.

A noisy air fryer can be alarming, but not every sound means your appliance is broken. Some noise is completely normal, while other sounds are warning signs you shouldn’t ignore. Here’s how to tell the difference and what to do.

Normal vs. Worrisome Noises

The Sounds You Should Hear

Your air fryer has a powerful fan that circulates hot air at high speed. This creates a low droning or whirring sound that’s a natural part of the cooking process . Think of it like a small hairdryer—it’s supposed to make some noise. Most air fryers create around 50dB of sound, which is about the level of a quiet conversation .

Normal sounds include:

A steady fan blowing sound
A consistent whirring or humming
The click of the basket locking into place

The Sounds You Should Worry About

Loud, unusual noises are a different story. These could indicate damage or a safety risk . Kitchen appliance expert David Rees explains that if you hear strange sounds or your air fryer is noisier than normal, it suggests the fan or motor may be damaged .

Watch out for these warning sounds:

Grinding or scraping
Rattling or banging
Gears grinding together
Sudden change in noise level

Most Common Causes and Fixes

1. Food Debris in the Basket

This is one of the most common causes of rattling. Crumbs, loose seasoning, or bits of food can get stuck under the crisper plate or around the fan . When the fan spins, these pieces bounce around and create noise.

The Fix: Let the air fryer cool completely. Remove the basket and crisper plate, and clean out any debris. Always unplug the appliance before cleaning or inspecting it.

2. Foil or Parchment Paper Flapping

If you use baking paper or foil, the powerful fan can lift it and create a flapping or tapping sound . This isn’t just annoying—it can block airflow and create a fire hazard if the paper touches the heating element.

The Fix: Make sure any liners are weighed down by food. For extra protection, use reusable silicone liners or perforated parchment designed specifically for air fryers .

3. Uneven or Wobbly Surface

An air fryer sitting on an uneven counter can wobble during use. This vibration makes the whole appliance louder and can create rattling sounds .

The Fix: Place your air fryer on a flat, stable surface. Make sure it’s not sitting on top of the power cord, as this can also cause vibration .

4. Loose Parts or Components

Over time and with heavy use, parts like the basket, drawer, or handle can become loose, especially in cheaper models . This creates rattling when the machine is running.

The Fix: Check that all parts are fitted securely before use. Tighten any loose screws carefully if possible .

5. Grease Buildup on the Fan

Over time, grease and debris can build up on the fan blades or the heating coil. This buildup can cause the fan to become unbalanced or obstructed, leading to strange noises .

The Fix: Clean your air fryer regularly—after every use or every few uses, depending on what you cook. Pay special attention to the area around the fan .

6. Internal Fault (Fan or Motor)

If you’ve tried everything and the noise is still there, it could be an internal issue with the fan or motor . Some models may display an error code like E4, which can indicate restricted airflow or a fan problem .

The Fix: If cleaning doesn’t solve the problem, stop using the air fryer and contact the manufacturer or an authorized repair service .

When to Replace Your Air Fryer

If the strange noises persist after cleaning and checking for loose parts, it might be time to replace your air fryer . Experts recommend this as the best course of action when unusual grinding or scraping sounds indicate internal damage .

Karl Bantleman, from fire and safety service Direct365, advises: “If you notice that your air fryer is noisier than usual it is important to take precautionary measures to ensure that it is still safe to use. While a noisy air fryer can be down to many factors, it could be an indication of more serious issues, resulting in an electrical hazard” .

He also recommends regular maintenance: “Don’t wait for your air fryer to make loud noises before you check it over. Instead, inspect your air fryer every month or so to ensure that it is in correct working order to minimise electrical hazards from occurring” .
