on the 2 stove top burners, 2 diagonal burners do not spark or light up.
I purchased 2 ceramic ignitors (WBK13K29914) and replaced them and it still does not spark or light up.
It it the spark modulator?
Answer Steve, You're going in the right direction, when you turn on any valve all the igniters should spark. You'll need to check the wires to the two igniters that don't spark, make sure they're not broken or shorted to the chassis and replace the spark module WB13T10046 if alls OK.
I have a GE profile cooktop (about 9 years old). one burner will not spark. I have replaced the ignitor, the switch assembly and the spark module (in that order). I inspected the wire going to the burner in question and it looks good, no evidence of burn, the insulation on the wire appears intact and is not hard or brittle. So far I think I just bought a lot of unneeded parts. Any ideas would be appreciated.
Answer Hello Bill,
When only one surface burner isn't working, it is normally because of a dropped ground. The ignitor has to have a good ground to spark to, as you know the circuit has to be complete back to ground. The cook top is made up of multiple steel parts, all screwed together. The way I usually restore normal operation is to remove all of the parts that are screwed together and use a piece of 120 grit sand paper to "clean" the surfaces that contact to complete the ground up to the ignitor area. This will solve the issue 99% of the time. The other 1% is a bad ignitor, start switch, or spark module. Since you have replaced them already, the ground will be the issue.
Constant sparking at all burners. Tried to "heat" the switches with a hair dryer, no luck, still sparks. Also tried to segregate each burner by disconnecting each , one by one, burner at the module. The sparks jumped across the module and couldn't determine which or if it is a switch on the harness of the spark ignition switches.
Please advise the proper item(s) needed to repair
Answer Richard, Disconnecting the electrode wires, is not going to pin point the problem. You need to test for 120 VAC on the end of the red wire at the spark module to chassis ground, with all the switches in the off position. If you have voltage on the wire, you have a bad switch and need the WB18T10366 switch abd harness assembly. If you have no voltage on the wire, then you need the spark module WB13T10046
