LiftMaster K175C0147 175C147 175C123 Light Socket Kit
The LiftMaster K175C0147 light socket kit is a replacement lamp socket for select LiftMaster and Chamberlain residential garage door openers. The socket holds the opener light bulb and connects it to the opener lighting circuit. When the socket is cracked, loose, heat damaged, corroded, or no longer making proper contact, the opener light may flicker, fail to turn on, or work only intermittently.
This part is commonly cross-referenced with 175C147, 175C123, and 175C0147. It is used across various LiftMaster and Chamberlain opener applications, but light socket fitment is highly dependent on the operator housing, socket shape, and parts diagram. Do not assume every LiftMaster or Chamberlain opener uses the same socket. Match the original socket and the parts diagram before ordering.
Before replacing the socket, check the bulb, bulb wattage/type, opener light settings, and signs of heat damage. Using bulbs that exceed the opener rating or do not match the opener requirements can shorten socket life or damage nearby plastic parts. If the socket or wiring shows burning, melted insulation, or repeated failure, the opener should be inspected by a qualified garage door technician.

Technician Note
A failed opener light is not always a failed socket. Check the bulb, light delay settings, wall control setting, and board output before replacing the socket. Replace the socket if it is physically damaged, heat damaged, loose, or called out by the parts diagram.
Before Ordering
- Confirm the opener model number and parts diagram.
- Compare the original socket part number, shape, mounting, and wire connection.
- Check for heat damage around the opener lamp area.
- Use the proper bulb type and wattage specified by the opener manufacturer.
- Do not service wiring with power connected.
Professional Advisory
If the socket is burned, wires are damaged, or the light circuit appears to have failed at the board, have the opener inspected before installing parts. Do not perform live electrical testing unless you are qualified.
