This is the replacement thermostat knob for your oven. It is made of black plastic and has temperature settings printed on it. The thermostat knob connects to a shaft on your oven and allows you to turn the oven on and off, adjust the temperature, and use the broil setting. If your old knob is worn, stripped, damaged, or missing, this is the part that will replace it. To replace the thermostat knob, carefully remove it from the shaft and replace it with the new knob. This part is sold individually and is an OEM part sourced directly from the manufacturer.
