If your air fryer's fan is running but the food isn't getting hot, don't panic — it's usually one of a few simple, fixable causes. Here's how to work through them.
Key takeaways
Q: Why is my air fryer not heating up?
A: Most often the basket isn't fully seated, the timer or temperature isn't set, or there's a thermostat or element fault.
Q: What's the first thing to check?
A: That the basket or drawer is pushed fully in — many won't heat otherwise.
Common causes
- Basket not seated — most air fryers have a safety cut-off and won't heat unless the basket or drawer is pushed fully home.
- Timer or temperature not set — some models need both a time and a temperature before they start.
- Power issue — check the socket and plug; try another socket. See tripping the electrics.
- Thermostat or element fault — if the fan runs but it never heats, the heating element or thermostat may have failed.
When to replace it
If the basket is seated, the time and temperature are set, the power is fine, and it still won't heat, the heating element or thermostat has likely failed. These usually aren't worth repairing on a budget model — check the warranty, and contact the manufacturer or replace the unit rather than attempting an electrical repair yourself.
Frequently asked questions
Why is my air fryer not heating up?
Usually the basket or drawer isn't pushed fully in (triggering a safety cut-off), the timer or temperature isn't set, there's a power issue, or the thermostat or heating element has failed.
What should I check first if my air fryer won't heat?
Make sure the basket or drawer is pushed fully home — most air fryers have a safety switch and won't heat until it's properly seated.
Is an air fryer that won't heat worth repairing?
If the basics check out and the element or thermostat has failed, it's usually not economical to repair a budget model — check the warranty and consider replacing it rather than attempting an electrical repair.
