I have installed a new ignitor on a Whirlpool gas oven SF375PEWN3 twice and each time it ignited and burned out immediately. I have checked the voltage and it is alright. The broiler works just fine. I have just tried a 3rd ignitor and it started to do the same thing before I disconnected it.

Have you touched the igniter coil with your fingers?

I haven't touched the ignitor with my fingers as I no any oil on it could cause a problem.

[caldwellczech]

Gene, I haven't touched the ignitor with my fingers do you have any other suggestion to correct the problem

[Gene]

Disconnect the igniter wires and measure the voltage between each wire and ground while the thermostat calls for Bake. Post the results.

Gene.
What is the part number of the igniter you installed?

[caldwellczech]

Haven't tried checking the voltage that way yet. The ignitor part #786324.

[Gene]

Another idea on what could cause this problem - the wire from the gas safety valve to the igniter can be shorted to ground. In such case power to the igniter would not go through the gas safety valve.

Eliminate the wire which goes from the igniter to the gas safety valve and use a new, preferably hi temperature insulated, wire to connect the igniter to the gas safety valve. It should solve the problem.

Gene, Does a shorted gas valve cause the ignitor to get to much current and burn out. The gas valve is shorted.

[Gene]

It's not shorted. There is a bi-metal inside the gas valve which shows close to 0 Ohms resistance. It is normal unless it's sorted to the ground. Have you checked that wire?

Don't understand how that ground could be shorted since it is not touching anything.
