Gas oven won’t heat up? It could be your iginitor

Question: The ignitor on my General Electric gas stove burned out. Can I manually light my stove? The burners on the top of the stove work fine.

Answer: No, this is not possible due to the gas being controlled by the gas safety valve. You need the ignitor to be working properly before gas is allowed out of the gas safety valve.

The ignitor is a small round or rectangular (flat oven ignitor and the round oven ignitor) device located near the burner and is wired in series with the gas safety valve. When the ignitor is cold, it has a lot of resistance, meaning it gets most of the electricity in the circuit. As the ignitor heats up, its resistance drops allowing the heat to pass to the bi-metal strip in the gas safety valve, which then allows gas to be released to the burner assembly. The gas then gets ignited by the glow-bar ignitor. The ignitor glows the whole time the burner is on, keeping the gas safety valve open. The thermostat senses when the desired temperature is reached, and cuts off electricity to the gas safety valve and ignitor. has an article on “Gas Oven Glowbar Igniters” along with photos and some helpful tips if you plan on making this repair yourself.

  1. my rangemaster (leisure) gas oven will ignite, but the flames are not getting very high or reaching the required temperature.

  2. Hi Paula,

    It could be your ignitor. If you have a glow-bar ignition system, the glow-bar may be old and going bad. It will still glow, but not hot enough to open the gas safety valve. This is a safety feature that ensures there won’t be any gas available if it won’t ignite for sure. Try replacing the ignitor. It’s a relatively cheap part to replace.

    Sometimes the oven thermostat or oven sensor can be calibrated wrong, or it may be faulty. If your particular range has an oven that uses an electronic thermostat, and the oven temperature is off by tens of degrees, you probably have to replace it.

    On most units that have a mechanical thermostat, you can actually remove the thermostat knob, and adjust the knob to more accurately represent the actual setting of the thermostat. On many models, there’s a screw on the back of the knob with a small calibration plate or ring. You can loosen this screw and adjust the calibration plate. Remember to tighten the screw again. If yours isn’t adjustable, and the temperature is off by a large amount, you should just replace the thermostat.

    Check the oven temperature. You can monitor the oven with a calibrating thermometer to check whether or not your thermostat is off.

  3. My oven is slow to heat up, 45 min to 350. Ignitor and gas valve are both new. Flame is all blue at first and gets lazier with more yellow after 5-10 minutes. Gas is LP and ignitor reads 2.6-2.6 amps. Solutions??

  4. G.E. main oven wont work at all. top burners work fine as well as the bottom broiler. Is this an ignitor fix or an element replacement? or something else?

    • Probably an ERC issue check the micro switch which work with the door latch. If this is malfunctioning or stuck the main oven may believe the door is open therefore rendering it unable to work.

  5. Heating up a pizza at 450 degrees. Left the oven on by mistake for several hours. Now oven wont heat up. Relatively new gas oven. Any help appreciated. Thanks.
