Other possible problems include a faulty thermostat control loose or broken wires or a bad safety valve.
Gas oven pilot light on but no heat.
The igniter is the most commonly defective part for a gas oven that won t turn on.
If your gas oven is not working but the burners are the problem is probably the igniter.
On a pilot light system if there is no flame present hold a match or lighter to the flame aperture for at least the count of 10 to heat the thermocouple sufficiently to open the pilot feed valve.
Pilot ignition works with a pilot light or a small gas flame where it is responsible to light the burner of the oven.
Second the igniter gets hot enough to glow and ignite the gas in the burner assembly.
Replace it if it s bad.
First the igniter draws electrical current through the oven safety valve to open it.
The igniter has two main functions.
If there is a reset button on your furnace turn the valve to the pilot position and hold a flame to the dedicated pilot gas tube while pushing the button for about 30 seconds.
First confirm that the light is out.
The hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas.
If the oven has a pilot light you will see a gas tube that may or may.
This sequence normally takes about a minute.
Open the oven and expose the pilot and burner assembly by removing the cover plate and flame spreader if there is one.
The safety valves open allowing for the gas to flow to the pilot light to ignite the.
As the igniter draws electric current it will heat to a high temperature and glow as well as cause the bi metal in the oven safety valve to warp and open the valve releasing the gas to be ignited.
If your casserole won t cook because your oven isn t getting hot it s time to check the pilot light.
You can remove this component with a screwdriver and test it for continuity.
Relight a gas oven s pilot light.
As the thermostat is turned on and increased the burning flame gets bigger and envelops the thermocouple bulb of the oven s safety valve.
By far the most likely cause if you have a standing pilot pilot on all the time is the thermocouple has died.
