The Whirlpool WP4456181 has become a replacement indicator light designed for Whirlpool and KitchenAid stoves. This little but essential component works in conjunction with your oven's light bulb. When the oven light has been turned on, the warning light illuminates, providing evidence that the light is functioning. This is particularly beneficial when the oven light is set up within the cavity and not accessible from the outside. Replacing an incorrect indicator light is an easy process that typically requires removing a few screws or panels in order to reach the light socket. The new indicator light simply plugs into the socket, providing the obvious indicator that the oven light can be turned on.
