appliance repairman here?

1.........Electronic or hot surface ignition ovens DO NOT USE a thermocouple. Thermocouples are only used on pilot systems

2........Look up your brand model and see "what you have." Last time I messed with one (mine is an electric range) there was only the integrated valve and a hot surface device

3....If it has (2) above, and the ignitor glows it may be the valve is not opening, or that the ignitor has changed resistance. It's a crap shoot. The ignitor is cheaper so try it first.


3A........MAKE CERTAIN you actually have gas pressure.......Do all burners work as normal? Then you can assume "so"

4......If there is no controller other than the gas valve itself and a new ignitor did not fix it, then yeh........gas valve.


5....If the ignitor is NOT heating, then it could be the ignitor or the valve. With power disconnected, remove wire leads from the ignitor at the valve, check the ignitor for continuity and the gas valve terminals for continuity. Whatever shows open is bad

Generally ........not just ovens......hot surface ignitors can be a PITA because they are usually made from some brittle material, and "I guess" get more so with use. They can crack and become intermittent, start to heat and then quit, etc etc, or just plain "sometimes." I ALWAYS have a spare ignitor laying around for my gas furnace. I've replaced two
