I have a Whirlpool electric cooking range, the old electric coil type. Recently one of the indicator lights doesn’t work properly. It always stays on, even when all the knobs are on the OFF position. The others are all OK. What’s wrong and how do I fix it?
I wiggled the knob, punched it and gave it any possible hard time, but the red light just won’t go away… <sigh>
Thanks everyone for the suggestions. I’ll give it a try and let you know how it works out.

    You may have a bad control switch, not breaking the electrical connection to the indicator light when in the OFF position. If it is the switch, you will have to replace it. A new switch can be purchased at most appliance parts stores. It is best to bring the old switch, and the make and model of the range, to the parts store to ensure you get the exact same part, or the suitable replacement.

    If the indicator light is not quite as bright as the other indicator lights, you may have a loose or disconnected neutral wire. This can be at the source, or anywhere else from the source of power to the connection to the control switch itself. The lights and the clock are usually the only things on a range that use “only 120 volts”. All of the heating elements use 240 volts

    You can check if the range is getting the proper current by using a voltage tester at the wall receptacle. Measuring voltage between the two power holes you should read between 220 and 240 volts, but from the neutral hole to each power hole and you should read only 120 volts. If the neutral is loose or not connected to the receptacle, you will not read 120 volts, even though you read 220 to 240 volts at the receptacle between the two power holes.

    If the receptacle tests OK, you must check if the neutral wire is properly connected to the switch controls of the range. For this, you will have to remove the control panel of the range, exposing all of the wiring. If you can see a loose or broken connection, repair it and that should correct the problem.

    If you cannot “see” the problem visually, unless you have technician’s tools, you will have to check by testing for voltage readings where the wires connect to the controls. This can be very dangerous because you have to plug the range in while the wiring is exposed. If you have no talent or desire to check the voltage of the control wiring where they connect to the switches, play it safe and call a technician or someone with the confidence and skills to check it safely.

    If you cannot figure out which wire is which, look for a wiring diagram. If you cannot find one, a good trick is to replace the suspected bad switch with one that is good. If that does it, you know you have a bad switch. If it doesn’t, you have another problem.

    Fixing electrical problems are easy if you can “see” the problem with the naked eye, otherwise it’s a matter of a process of elimination.

    The pilot contact inside the switch is most likely fused together causing the indicator light to stay on constantly. You will have to replace the switch to that burner. Not hard to do – just make sure electric is disconnected before attempting repair.

    You can call the repair clinic @ their 800# and speak with the repairman for free help and advise.They also,have a diagram page that might help you out. Even a troubleshooting page too.
