Glenn B. for Model Number Model Number JGP328BEC2BB Serial # MD799902Q While no burners were being used all four igniters started sparking without being manually turned on. So I would like to know if it is the Harness Switch or Spark Module, because Harness Switch Hooked to the power (black wire) 120 VOLTS then reading the Yellow wire with switches off I still read 120 VOLTS which should have no voltage to feed the Spark Module right. All the Igniter work (they spark) there is no cracks in the porcelain to go to ground or shorts in the wire to the Igniters. The Spark Module has four wires that go to the Igniters then one wire to ground then stud and then a – for the white wire, +for the 120 volt that comes from the Harness Switchs, ( Yellow wire) and the other end to the Hot from the house 120 volts black wire, so when you turn a switch on it feeds the Spark Module, is that right ?
Answer Hi Glenn. Yes, if you are reading the 120 vac through the "open" switch, then you will need to replace the harness assy. This is part # WB18T10339. Thank You. Read More... Answered by AppliancePartsPros.com | Tuesday, February 21, 2012
