Ensure the entire appliance is off.
Gas oven pilot light on but no heat.
The hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas.
The igniter is the most commonly defective part for a gas oven that won t turn on.
It is a little probe that sticks into the pilot flame and has a copper tube or sometimes wire back to the gas controller if the thermocouple does not sense the heat of the pilot it prevents the gas controller from turning on the burners.
First confirm that the light is out.
Relight a gas oven s pilot light.
If your casserole won t cook because your oven isn t getting hot it s time to check the pilot light.
If your gas oven is not working but the burners are the problem is probably the igniter.
Second the igniter gets hot enough to glow and ignite the gas in the burner assembly.
This sequence normally takes about a minute.
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.
You can remove this component with a screwdriver and test it for continuity.
First the igniter draws electrical current through the oven safety valve to open it.
The igniter has two main functions.
Replace it if it s bad.
Other possible problems include a faulty thermostat control loose or broken wires or a bad safety valve.
If the oven has a pilot light you will see a gas tube that may or may.
The safety valves open allowing for the gas to flow to the pilot light to ignite the.
As the thermostat is turned on and increased the burning flame gets bigger and envelops the thermocouple bulb of the oven s safety valve.
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.
Pilot ignition works with a pilot light or a small gas flame where it is responsible to light the burner of the oven.
Then turn the gas valve to the off position and wait five minutes.
