Why does my air fryer heater keep clicking off?
Heater relays can repeatedly click off and cut power during initial heating, requiring multiple power cycles or drawer openings before staying energized. This prevents appliances from functioning normally on the first try, forcing users to manually restart them several times just to get them to heat up.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Opening and closing the drawer repeatedly
- 2Turning the unit off and on multiple times until the relay stays energized
- 3Checking continuity and resistance on the thermistor and thermal fuse
- 4Swapping the heating and fan relays
- 5Reflowing terminals and relays
- 6Replacing the control board and transformer
- 7Cleaning the heat exchanger
- 8Swapping blower power leads so that the fan runs at its fastest speed
- 9Checking the actual temperature with a thermometer to see if it is actually tripping at 190

“I have a 2009 ICP gas furnace that keeps shutting down during the heating cycle.”source ↗
“other than replacing the high limit switch, is there anything else that I can check before determining that the issue is with the heat exchanger itself and needs to be replaced?”source ↗
“We have a Russell and Hobbs air fryer which won't heat up initially but if you keep opening and closing the drawer, it eventually heats up.”source ↗
“each time you open and close the drawer or turn the unit off and on, it will heat up a bit and the heater relay will click off, like it has lost voltage until after maybe the 4th or 5th time, the relay stays energized and the air fryer functions as intended.”source ↗
