I have a 5 year old GE 5 burner cooktop. When I turn off the right front burner the red light ( on the knob ) stays on and the burner keeps clicking. If I turn the circuit off and light the unit with a match, all is well. Any opinions? Could this be something I might be able to fix by myself. Needless to say, a visit from a GE repairperson will be several hundred dollars. Thanks!
