LiftMaster 175C147 Light Socket

The LiftMaster 175C147 Light Socket is a genuine OEM replacement lamp holder designed for select LiftMaster residential garage door openers. It restores the opener’s courtesy light function by providing a reliable connection point for a standard screw-in bulb, helping illuminate the garage when the door operates or when the light button is pressed. This replacement part is ideal when the original socket is cracked, heat-damaged, or producing intermittent lighting, and it maintains compatibility and performance as specified by LiftMaster for the applicable models.

Installation is straightforward for most DIY repairs: disconnect power to the opener, remove the light lens, unscrew the bulb, swap the faulty socket for the 175C147 in the same mounting location, and reconnect the wiring as originally configured. Always use the bulb type and maximum wattage specified in your opener’s owner’s manual, and ensure power is off during service. As a LiftMaster factory part, the 175C147 integrates seamlessly with the opener’s lighting circuit for dependable everyday operation. Verify compatibility with your exact model using the LiftMaster parts diagram or support resources before ordering this replacement light socket.
