Light that won't go off

Oven Repair (including Ranges and Cooktops)
1

Hi.
I have a Whirlpool rf262lxsb that is a smooth top range.
It has two indicator lights. One is burner on indicator and the other is a hot surface indicator.

My right front large burner has an issue that sometimes when I use it, when I turn it off, the burner on indicator does not go out. I noticed today that the screws were loose behind the burner knob. I did tighten them, but it still did not cause the light to go out. It has done this on occasion before and sometimes if I play with the knob, I can get it to go off. I have not been using the burner, but one of my teens used it today. The burner is not hot, but the light continues to stay on. I don’t think it is the light itself since it only does it with this burner.

After doing some searching, I suspect it is an infinity switch for the control knob which would lie behind the control panel on the top rather than one which lies below the surface of the glass top. But before I go buy something, I wanted to be sure someone more professional gave me their opinion.

Thoughts?

Here are your parts

I for one agree with you that it is probably the element infinity switch.
It is what controls the the lights, see the attached wiring diagram.

The indicator light for "burner on" does not go out when all burners are off. I replaced the element infinite switch for the burner I thought was having the issue however the remains on. I am assuming that indicator switch itself is good because the light works. What part do you recommend to solve this issue? Thank you.

I’m personally don’t like guessing in such situation. The simple continuity test will save your time and money and make repair more reliable.

Turn off the power to the range. Access the infinite switches. Doing one switch at a time, remove the wire connected to the infinite switch terminal P. Be sure the switch is Off and, using a multimeter, check for continuity between the terminals P and L1. If it reads continuity, this switch would need to be replaced. Also, check the wires connecting the indicator light and all switches.
