My GE cooktop stopped sparking, so I just replaced the spark module with NO luck. I dont really know how to troubleshoot the problem. Do I need a new transformer, switch igniters, or the ignitors??? Thanks.
Answer Hello Howie,
The first thing to check is to make sure that you have power to unit. Check the outlet that the unit is plugged into to make sure that there is 120vac coming to the outlet. If you have power to the outlet the you would want to check to make sure that you are getting 120vac to the transformer. If you are not getting voltage to the transformer but are to the wall outlet then you have a bad power cord WB18X10170. If you are getting 120vac to the transformer then check the output of the transformer for 230vac. If you are getting the 230vac then you have bad ignitor switches WB18X10169. If you are not getting 230vac then you have a bad transformer WB27X10905. 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
