Whirlpool Range GW399LXUS4 Touchpad does not respond

This membrane switch is the thin keypad mounted behind the control console that sends your button presses to the electronic control. Replacing a worn membrane restores reliable input when keys stop responding or register intermittently. What it does:

• Detects button presses and relays them to the control board
• Common fix for unresponsive or intermittent keys
• Can address "stuck key" beeping or key-related error indications
• Restores ability to select settings and start/stop functions

• 1 membrane switch

• Disconnect power before servicing; on microwaves, high voltage can remain—use proper discharge procedures.
• Remove the control panel/console to access the keypad.
• Handle the ribbon cable carefully; fully seat the connector.
• Clean the mounting surface and align the new membrane before pressing into place.
