Cause 1 Spark Ignition Switch One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the spark ignition switch fails with the electrical contacts closed, the switch will send continuous voltage to the spark module. To determine if any of the spark ignition switches is defective, use a multimeter to test each of the switches for continuity. If a spark ignition switches shows continuity at all settings, replace it. Cause 2 Spark Ignition Switch and Harness One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the switch contacts are wet or stuck in a closed position, the switch will send continuous voltage to the spark module, no matter where the dial is set. Each of the switches can be tested individually to determine if they are shorted. If a spark ignition switch is shorted and is not wet, or if drying it out doesn’t solve the problem, replace the switch. Cause 3 Spark Module The spark module provides power to each surface burner spark electrode. If the spark module fails, it may cause the burners to spark continuously. However, the spark ignition switch is more likely to be at fault. Before replacing the spark module, first test the spark ignition switch. If the spark ignition switch is working properly, consider replacing the spark module.
Cause 4 It could also be the outlet that the range or range top is plugged into. You can test this by plugging the range or range top into an extension cord and running it to another wall outlet. If the periodic sparking stops, then your problem is the outlet or another electrical problem apart from the range itself. At this point it’s best to call an electrician.
I have the same problem with a brand new cook top. Sparks all burners all the time. Got a warranty repairman who checked all the switches and said it was the module. The warranty people could not locate the obsolete module and gave up. I bought the listed replacement for the model and installed it myself. The only real difference was that the switches had individual hard wire running to the old module while the new one took only one ganged load, so I wired them all together and attached them to the load lug. Still the same problem. Tried the drop cord to another outlet across the room. Problem persists. In the off mode, I have 118 VAC to ground on the hot side and 0 on the output side of each switch. When lit, I get an HV indication on my meter and a wildly changing voltage to 4 digits, not 118 VAC. My meter does not read high voltage to 10-15,000 volts. How about some bleeding from the HV ? Where would it come from? Possibly the ground? Would the common ground be the source? Where would you look? The new module has no ground at all and is in a plastic case. The old module did have a ground for its internal wiring through the attachment plug. The cooktop unit is grounded.
I had the same problem .Turn the cooker off so that it stops sparking or switch the main electricity off . Then clean the ignitors .Take off the cooker knobs and check for any debris there.Clean it ,hover it .It should hopefully sort out the problem .I had the same problem .In one of the knobs after removing it , some rice are other stuff was in there causing all the problem.Once cleared all was fine.I hope this helps.Make sure it is off when you clean the ignitors.
