The oven burner igniter
commonly known as the hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. 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. This sequence normally takes about a minute. Igniters come in both flat and round styles and are very fragile. If the burner does not light then you should check the igniter first. If the igniter does not glow at all, then check for power to the circuit. This is a live voltage check and should be performed by a qualified person. If power is present then the igniter may be open circuit and can be checked for continuity with a multi-meter. If the igniter is glowing, but the burner is not lighting, the igniter may be weak and still be at fault because it requires a certain amount of current draw to open the valve. This check requires the use of an amp meter and should be performed by a qualified person. If the igniter is defective then it must be replaced.
The reason the oven igniter will come on yet their is no heat in the oven is because that igniter is weak and not drawing the proper power to allow the gas valve to open. By replacing the oven igniter it will open the gas valve and once again heat the oven.
When the bake igniter becomes weak or burns out, your oven would not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.
If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve would not let the gas out into the oven burner. A weak igniter must be replaced.
A faulty igniter is probably the most common cause, however there are others:
-- defective thermostat -- defective selector switch -- defective gas safety valve -- defective gas valve coils(This will be the next possible issue if the igniter is functional)
A lot of times the problem is with a dirty or a clogged burner. Make sure the burner is clean. If you have a pilotless model, it uses a spark igniter to ignite the gas, which works in a combination with a spark switch (located on the burner gas valve) and a spark module. Because it is not simple to test these parts and find out which one is defective, we recommend to contact a professional appliance technician.
Jrzy, even though you can see the bake igniter glowing, that doesn't mean it's good. Igniters actually get weak (unlike a light bulb that simply burns out). It's hooked up in series to a safety valve (the valve that allows main gas into the oven) which actually reads the amps flowing through the igniter. If the igniter is weak and the amps are too low, the valve won't open up.
Replace your igniter and you'll be cookin' with gas again.
Tip---> before you unscrew your old igniter, put a little liquid dish soap on the threads for lubrication. This'll ensure it comes out with no problems.
