Introduction: Most modern ovens which are built today use a bar which glows to ignite gas for cooking. It is synonymous to a glow plug in a diesel engine. The top burners use a spark ignition which is synonymous to a spark plug in an internal combustion engine. Now, to explain the theory behind the glow bar, there are two designs: flat & round. The bar is wired in a series circuit with the gas valve. When the bar glows, it will continue to allow more current & voltage to pass into the valve until it get to its full brightness. At this point, it will allow the valve to fully open, and transfer gas into the burner assembly. The igniter will ignite the gas, and create a flame. If this bar does not come up to its full brightness, it won't allow the valve to open as a safety feature. A sign of a failing igniter is an oven which takes a few minutes to start, then cuts out with an occasional smell of gas. Safety: Always try to unplug the oven or turn off the circuit breaker before servicing an electrical appliance. Your work area should be clean, and dry. This is the inside of the oven with the front door removed for easy access: You have to remove the two corner screws to get to the igniter: This is a picture of the weak igniter trying to start the oven: The next step is to remove two small hex head screws holding the igniter to the burner assembly: The original factory igniter was pushed slightly inward. It's not necessary to make this part so close. Excess heat is not good for the ceramic element. This is the bottom of the oven with the lower pull out drawer removed: You could see part of the electrical plug in this picture. Here's a close up view of the connector which has to be unplugged: Here is a picture of the new igniter: Now it's time to install this new part. The two screws are getting tightened while the igniter is kept straight: Here's the test. The oven is turned on, and the igniter is glowing at full brightness: It's a little hard to see the blue flame in this picture but the oven is now on! Wait until everything cools down, and replace the inner tray, racks, door, and drawer.
