My air fryer doesn’t heat up anymore, how do I fix it?
Are you having a heating problem trying to make chips in your oil-free or air fryer? In this troubleshooting guide, we explain what can lead to this failure and help you solve the problem.
THE POTENTIAL CAUSES OF THIS FAULT:
-
Thermal safety malfunction
-
Thermostat or sensor problem
-
Heating coil defect
-
Control board out of service
WARNING
Before carrying out any work on your appliance, be absolutely sure that you first completely disconnect it from the mains electricity supply.
Risk of electric shock.
Wear protective gloves if you need to disassemble the appliance.
Risk of cuts and abrasions.
Thermal safety is cut off
Some fryers are equipped with thermal safety. It is used to cut off the power supply in the event of overheating. To find out if this part is faulty, it must be tested with a multimeter in the 200 Ohm position or ohmmeter if it is self-calibrating. The expected value is 0.1 Ohm. If no value is displayed, it means that this security function is faulty. For some appliances, the fuses are not sold individually, so part or all of the wiring will need to be replaced. We do not recommend using a soldering iron to set up new wiring because these type of wires dislike heat.
The thermostat or sensor is faulty
Depending on your device, it will be equipped with either a thermostat or a probe. These components regulate the temperature of the device.
- If your air fryer is equipped with a thermostat, when you turn it a contact point closes and voltage passes over the coil. If this element is defective, the electricity will not flow where it is supposed to and the air fryer will not heat up. To test it, you need a multimeter set to 200 Ohms. You need to open the thermostat and place the key tips on each terminal. If you get a low reading, the thermostat is working fine, if not, it will need to be replaced.
- If your device works with a probe, the value may differ depending on the model.

The coil no longer heats up
The coil is the heating element of your appliance. If broken, your oil-free fryer will no longer be able to work. To test its resistance, use your multimeter in the ohmmeter mode. The expected value is between 20 and 60 Ohms. If your coil shows no reading, it is defective and will need to be replaced.

The control board is defective
The control board manages the voltage within the device. If it does not send any information, the heating element will remain cold and the device will not be able to operate. Make sure that you have checked all other components of the air fryer correctly before attempting to replace the control board.
