If the burners spark all the time and won't stop, one of the burner spark ignition switches is probably defective. This is a common burner spark problem. Mounted on each burner control valve is a small switch, as the knob is rotated to the "Lite" position electrical contacts in the switch are pressed together and provide power to the spark module. If the spark ignition switch is defective the contacts may stay pressed together, causing the burners to spark all the time. First determine which of the switches is defective and then replace it. Spark ignition switches are not repairable.
