Robert S Hollister , CA August 26, 2016 Appliance: Whirlpool 30" Sealed Gas Cooktop SC8640EDQ6 Whirlpool Cooktop Sc8640edq6: No spark at any of the four burners. How to replace Top Burner Igniter. Sealed burner gas cooktop has to be removed from the counter top in order to disassemble. This means disconnecting the gas line. To disassemble the unit you will have to remove the gas line regulator. Once the unit is separated you will see the spark module. I replaced the module. Note: Because the new module has been updated from the original it does look different. I suggest you put the new module along side the old taking one wire at a time from the old to the new. If your unit is as old as mine (15yrs) I suggest replacing all the burner ignitors while you have the unit apart. All said and done the new spark module fixed the problem. 16 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
