How do I know if my LiftMaster gears are worn out?

If the motor runs but the chain or belt does not move, or if you find white plastic shavings inside the opener housing, the gears are likely stripped and need replacement.

Are LiftMaster gear kits universal?

Most gear and sprocket kits fit a wide range of LiftMaster chain-drive openers, but you should always check your opener’s model number before ordering.

Can I replace the gears myself?

Yes, with basic tools and mechanical ability. The process involves opening the motor housing, removing the old gears, and installing the new kit. Always disconnect power before attempting repairs.

How long do LiftMaster gears typically last?

With normal use, gears usually last 8–12 years. Heavier doors or poor lubrication may shorten their lifespan.
