Burners on electric stoves can malfunction in a number of strange ways. Sometimes, the burner might heat up far too much and only work when it's turned up too high. \
This is a particular error that occurs when the burner is getting too much electricity as a result of a damaged or malfunctioning infinite switch. This is the part of the stove that controls the flow of electricity and when it's not working, it can send too much electricity and end up giving you a burner that only works at a high heat. \
