Gas Oven Pilot Light On But No Heat

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.

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. Pilot ignition works with a pilot light or a small gas flame where it is responsible to light the burner of the oven. Ensure the entire appliance is off.

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. 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. The igniter has two main functions.

Second the igniter gets hot enough to glow and ignite the gas in the burner assembly. The igniter is the most commonly defective part for a gas oven that won t turn on. This sequence normally takes about a minute. You can remove this component with a screwdriver and test it for continuity.

If your casserole won t cook because your oven isn t getting hot it s time to check the pilot light. First the igniter draws electrical current through the oven safety valve to open it. 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. Replace it if it s bad.

Then turn the gas valve to the off position and wait five minutes. The hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. Relight a gas oven s pilot light. If your gas oven is not working but the burners are the problem is probably the igniter.

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.
