I have these cooktop but the spark its not working and the lights on the knobs don't turn on what parts should I check?
If the knobs are turning to light the unit but will not spark then you will want to check the spark ignition switches and if they are good then the spark module is faulty.
Replaced the Spark module, however still no clicks on the ignitors to light. All works well lighting with a match on all burners. I am guessing that the Transformer most be bad??
You will want to check the ignition switches for the burners. In the light position the switches should have continuity. If not then the switch is bad and would need to be replaced. If the switches check ok then the issue would be the transformer.
