This is the replacement surface burner switch for your range. It measures approximately 1.5 inches by 1.5 inches, with a shaft that is approximately 1 inch long. The surface burner switch turns the surface element on and off and allows you to control how much heat the element produces. The main reason to change the infinite switch is if the switch has shorted out inside, and is not allowing power to the burner, or if the contacts inside are stuck together and the element is stuck on high. Ensure that the burner is off, and the range has been disconnected from the power source before you begin this repair. This part is sold individually and is an OEM part.
