Gas Oven Igniter Pilot Light

The hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas.

Gas oven igniter pilot light. If the igniter does not glow at all use a multimeter to test the igniter for continuity. 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. In this hvac training video i show up close how the thermocouple pilot light and gas valve work on a water heater furnace fireplace as well as other ap. An unlit pilot can also prevent your premier gas range s oven from igniting.

An electric igniter or a pilot light flame that remains lit becomes the ignition source for the gas. Check to see if the issue is with the gas supply lines or the igniter itself for gas stoves. 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. Relight a gas oven s pilot light.

Many gas ovens especially older models may require you to manually light their pilot light in order to light the oven. If the igniter is weak replace it. To relight the pilot turn the oven control knob to the off position and remove the oven s broiler carriage. If your casserole won t cook because your oven isn t getting hot it s time to check the pilot light.

If the igniter glows for more than 90 seconds without igniting the gas flame this indicates that the igniter is too weak to open the valve. To determine if the igniter is defective observe the igniter when the oven is on. On a pilot ignition oven there is a pilot which is an actual gas flame although very small in the oven. This sequence normally takes about a minute.

What happens in this system is that the pilot stays lit all the time and when the oven thermostat is turned on the pilot flame extends gets bigger to envelope the thermocouple bulb of the oven safety valve. It s important to take safety measures like making sure the oven is off and your kitchen is well ventilated before you attempt to light the pilot light to avoid lighting standing gas. If your stove top igniters are working fine but your oven won t light then you don t have an issue.
