The Whirlpool WPW10207935 Range Switch Membrane is a crucial part of your Whirlpool range's control panel. It consists of a thin, laminated plastic sheet with pressure-sensitive sections which correspond to the numerous buttons and features on your range's touchpad. When you push a button on the touchpad, you are applying pressure to the membrane. The membrane then transmits this pressure electrically to the range's control board, which analyses it and starts the correct operation, such as turning on a burner or altering the oven temperature. This membrane switch must be installed for user interaction with your Whirlpool appliances. Without an operational membrane, your range's touchpad would be able to register your button presses, making the appliance unusable.
