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.
Gas oven pilot light on but no heat.
Open the oven and expose the pilot and burner assembly by removing the cover plate and flame spreader if there is one.
If the oven has a pilot light you will see a gas tube that may or may.
By far the most likely cause if you have a standing pilot pilot on all the time is the thermocouple has died.
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.
The safety valves open allowing for the gas to flow to the pilot light to ignite the.
Replace it if it s bad.
Ensure the entire appliance is off.
If your gas oven is not working but the burners are the problem is probably the igniter.
Then turn the gas valve to the off position and wait five minutes.
Other possible problems include a faulty thermostat control loose or broken wires or a bad safety valve.
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.
As the thermostat is turned on and increased the burning flame gets bigger and envelops the thermocouple bulb of the oven s safety valve.
The hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas.
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.
First the igniter draws electrical current through the oven safety valve to open it.
You can remove this component with a screwdriver and test it for continuity.
The igniter has two main functions.
Relight a gas oven s pilot light.
The igniter is the most commonly defective part for a gas oven that won t turn on.
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.
