Air Fryer Not Turning On or Not Heating
Air fryers have safety interlocks that stop them running if the basket is not fully in — so a unit that "won't turn on" is often just not seated. Here is the fast diagnosis.
1. Seat the Basket Fully
Most air fryers will not run unless the basket/drawer is pushed completely closed, which trips a safety switch. Pull it out and firmly reinsert it until it clicks. This is the number-one reason an air fryer "won't turn on."
2. Check Power and Outlet
Plug it directly into a wall outlet, not a power strip or extension cord — air fryers draw a lot of current and can trip strips. Test the outlet with another device, and check the breaker/GFCI if it is dead.
3. Let It Cool (Overheat Shutoff)
If it was running and shut off, the thermal cutoff may have tripped from blocked vents. Make sure the rear/top vents are not against a wall or cabinet, let it cool 30 minutes, and try again.
4. Runs But No Heat
If the fan runs but it never heats, the heating element or thermostat has likely failed. On an inexpensive unit this usually is not worth repairing — replace it. Make sure you actually set a temperature and time, as some models default to a fan-only or low setting.

FAQ
Most often the basket is not fully seated (it trips a safety switch), or it is on a power strip that tripped. Reinsert the basket firmly and plug directly into a wall outlet.
The heating element or thermostat has likely failed. Confirm you set a temperature, ensure vents are clear, and if it still will not heat, replace the unit.
