Greg for Model Number JGP337WEJ2WW My cook top sends out a spark every 1 minute or so, I changed the ignition module and replaced electrodes to no avail, replaced another module thinking I got a bad one and still the same. I reviewed the switches and they all look good but my next step is to replace them. When I plugged multi-meter on ac-hot and neutral at the module, I got readings of up to 250mVAC when the module discharged and then volts would drop down approx. 100mVA and continue to rise to 250, discharge again and so on (this is happening while no switch is turned on). When you turn each knob the module works properly discharging at a normal rate every few seconds. Any idea what could cause this,
Answer Hello Greg. First check for bad wiring on the unit causing it to ground out. If it is good, you will need to go to the spark switches on the unit next. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
