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.

“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 ↗
“The burners light normally, but the spark keeps clicking even while the burners are on. After about 5 seconds, the burners shut off. The blower keeps running for a bit.”source ↗
“The FLAME light never comes on, even when the burners are lit.”source ↗
“It seems to be a yearly issue with it, and after multiple calls to professionals who come and say they fix it only for it to have the same issue within a few days.”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 ↗
“PS920Sf3SS GE Oven is turning on the oven to dangerous temps when the warmer is turned on.”source ↗
“Yes, the warmer is at normal temp, but the oven turns on as well (not supposed to) and the heat runs away (also not supposed to)”source ↗
“The oven stays off, and the broiler element is energized”source ↗
