LiftMaster

Keep your LiftMaster garage door opener running with genuine replacement parts. We stock the components that actually fail: stripped drive gears and gear kits, logic boards and circuit boards, sprockets, belts and chains, rail and trolley assemblies, capacitors, transformers, limit switches, safety sensors, wall control panels, and remote controls.

Use the model lookup below to jump straight to a labeled parts diagram for your opener — every diagram links directly to the exact part number, so you can identify what you need and order it in one step. LiftMaster and Chamberlain openers share most parts, so if your model isn't listed here, check the Chamberlain section by drive type.

Two problems account for most LiftMaster repairs. If your door only closes while you hold the wall button down, your safety sensor eyes are misaligned or blocked — start there. If the motor runs but the door doesn't move and you find white plastic shavings inside the housing, the drive gear is stripped: the 41A2817 gear kit fixes most chain drives, and the 41C4220 gear and sprocket kit covers the rest. Not sure which model you have? Check the label on the side or back of the motor housing, or the sticker inside the light lens cover.
