How do I know if my infinite switch is bad?

Common signs include a burner that is stuck on a single heat setting, fails to turn on or off, or does not respond to knob adjustments.

Is it safe to replace an infinite switch myself?

Yes, if proper safety precautions are followed. Always ensure the appliance is completely disconnected from power before beginning any repair. Take photos of wire connections before disconnecting them to aid in correct reassembly. If uncomfortable with electrical work, consider professional assistance.

What is the difference between an infinite switch and a thermostat?

An infinite switch specifically controls the power cycles to a surface burner for variable heat. A thermostat, typically found in the oven cavity, senses and maintains the overall internal temperature by controlling the bake or broil elements. They serve different functions in an oven.
