Two Quick Fixes
Door only closes while you hold the button? Your safety sensor eyes are misaligned or blocked — start there.
Motor runs but the door won't move, with plastic shavings inside? The drive gear is stripped — the most common Chamberlain repair. Check your model's diagram above for the matching gear or gear-and-sprocket kit.
GateHouse Supplies stocks genuine Chamberlain garage door opener replacement parts for belt drive, chain drive, screw drive, and wall-mount jackshaft models. Because Chamberlain and LiftMaster openers are built on the same platforms, most parts cross over between the two brands — if your model isn't listed above, check our LiftMaster parts pages by drive type. Each model page includes a labeled parts diagram with every part number linked directly to the item, so you can identify and order drive gears, gear and sprocket kits, logic and circuit boards, capacitors, sprockets, belts, chains, rail and trolley assemblies, safety sensors, wall control panels, and remote controls with confidence. All parts ship fast from our California warehouse.
