The LiftMaster 041C0279 Light Socket is a genuine OEM replacement lamp holder designed for select LiftMaster and Chamberlain garage door openers. It restores reliable illumination inside the operator’s light compartment, allowing you to use a standard medium-base household bulb on the opener’s 120V AC lighting circuit. This replacement part is intended for units that specifically list 041C0279 in their owner’s manual or parts diagram, making it an ideal fix for broken, burned, or intermittently working sockets on compatible residential garage door openers. It is commonly used as a direct swap to maintain original performance and compatibility with factory wiring and lens covers.
Installation is straightforward for DIY maintenance: disconnect power to the opener, remove the lens cover, replace the existing socket with the 041C0279, connect the leads to the matching terminals, route wiring away from moving parts, and reinstall the lens before restoring power. Always use a bulb type and wattage that match the rating printed on your specific opener and do not exceed that limit. Some bulbs can affect remote-control range; if using LED lamps, choose models recommended for garage door openers to minimize interference. For compatibility, confirm that your opener’s documentation calls for part number 041C0279 or consult the manufacturer’s parts list for your exact model.
