All 4 surface ignitors sparking at the same time when the switches are turned off.
Answer Hello Ebuck. Based on the information you provided, the spark switch is bad and will need to be replaced. You will need to test and see if a switch reads closed in the off position. If so, it is bad. 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
The ingitor clicks when the burners are off.
Answer Hello Dennis,
This is a shorted spark switch Y0301326 on the gas valve, (behind the knob).
