Michael S Cincinnati , OH August 15, 2015 Appliance: Model JGSP30GEP2BG Constant sparking even when no burners turned on and when disconnect the valve switches Had to replace the igniter module. Some key things I came to learn: 1. If you remove the bottom drawer, you can find an envelope there that is for the technician. It explains some things about how the igniter senses the flame, and some advice about diagnosis. 2. The igniter module on my model of slide-in range is located inside a box that is visible when you remove the bottom drawer. No need to slide the range out. 3. At each gas valve, there is a separate valve switch WB13ML or similar. It is not a harness of switches. I bought one of these for about 13 dollars before I even started disassembling. But when I disassembled, and removed the leads from each of the switches, none of them stopped the sparking. So it was not the problem. So I had to go buy the igniter module. 4. Out of the 3 screws per burner, 12 total, only 3 of them could be backed out. The other 9 snapped under the head. There was no way to use penetrant oil effectively. 5. I never did get the broken screws out of the tapped holes. So I could never install more than 3 replacement screws, but it all seems fine. It has been 3 weeks since repair. 6. The glass top comes off when all 12 screws are removed (or broken). No other big screws or clips holding it down. 7. Each of the steel drip pans is separate from the glass top. They are not bonded to the glass. Note: Dissassembly to possibly replace the 13 dollar valve was the hard part. Once had access, and knew it was not the switch, then the igniter module was not too hard to install. That alone was only about 1 hour or less.
