I have a Frigidaire electric range and one of the burners will only burn on "High," no matter what you set it to. Is it most likely the switch?

Answer Ron, You are on the right track, with a burner element, that only has a high heat setting, it would be most likely, that the infinite switch has a stuck contact, inside the switch. As long as you don't have a shorted wire at the element, a new switch should solve your issue. Good Luck.
