Lg Range LRE30453SB Light not working

The Membrane Switch Assembly is the touch keypad for your appliance's control panel. It relays button presses to the electronic control, restoring reliable input when keys stop responding or a "stuck key" error prevents selecting functions.

• Provides the printed keypad used to choose settings and start/stop
• Sends each key press through its flat ribbon lead to the control board
• Common fix for unresponsive or intermittent buttons
• Can resolve "stuck key"/keypad error beeps or messages
• Useful when the display lights but buttons do not respond

• Disconnect power to the appliance before servicing.
• Access the control panel; note screw and clip locations for reassembly.
• Handle the ribbon connector carefully—do not crease it and seat it fully.
• If servicing a microwave, internal high-voltage components can retain a charge even unplugged.
