I have a Kenmore electric cooktop, model 42645/42649/42656. One of the hot surface indicator light is stuck on, even though the burner is off and cool to the touch. We've tried turning the burner off and on, but the indicator light stays on. Any ideas?

Re: cooktop light stays on when cool
The "hot top" indicator lamp is switched by a contact on the plate cut-out. sometimes this cut-out is available as a separate part but often must fit complete plate. by plate i mean the bit that gets hot!

Most likely the problem is in the heat control switch.Cannot be repaired you will have to replace it. To make sure, swap it with one of the other burners that do not have the problem. If the problem goes away, you know its the switch.
How long does it take for the light to finally go off?or does the light ever go off when a cooktop decrease in tempreture has to reach the tempreture set by the factory for that light to go off. Sounds like a thermal switch which controls the hot surface light is stuck closed If this is a new unit, I'd return it. If not, I would check the switche(s) for the hot surface light -- when the unit is cold, unplug one wire going to the thermal switch and check it for electrical continuity. If you get current from a multi-meter through the switch, replace it -- it's not opening when it cools down.If you have any further questions please message me back and please remember to rank how this opinion has helped in your appliance situation Thanks again
if its going out, its probably ok
its not a light indicating the burner is on, rather that the glass is abcove 100 degrees and still not safe to put something on
2 hours is a bit long but it depends on how fst the surface can cool of
you can test this by trying to cool it off faster with a fan ans see what happens

hot surface light is turned on by a auxiliary switch across the plate. it is possible that the switch has stuck in the closed position. it is also possible that the plate is not turning off. feel the plate and check if it is at all warm. if not, then the auxialuary switch is stuck closed. not dangerous. to fix means replacing the limiter which is the rod you can see across the plate. sometimes you can only get the complete plate with limiter which is a bit pricey
you have a bad switch. You can check each switch for voltage going to the light one at a time, if your comfortable with that. Remember there is enough current there to seriously injure you so if your not comfortable around electricity, call in a service technician.
