Common Repairs
Door will not close and the light blinks. Safety sensors, nine times out of ten — and usually alignment or a stapled wire rather than a failed eye. See safety sensors.
Motor runs but the door does not move. On a chain or belt drive that is the gear and sprocket — the nylon gear strips. Find your model above; the gear kit is on its page.
Remote stopped working. Try a battery first. If several remotes fail at once it is the receiver logic board — see the logic board cross reference. The 893MAX replaces almost every older LiftMaster, Chamberlain and Craftsman remote.
Wall button dead. Wall controls are not universal — pre-1998 openers take a different panel from Security+ models. See wall controls.
Beeps and runs slowly during a power cut. Backup battery. It is a consumable and lasts a few years.
About LiftMaster Parts
LiftMaster and Chamberlain openers are built by the same manufacturer, so many parts — safety sensors, door arms, release hardware, chain and master links — are shared between the two brands. Part numbers usually begin 041 for assemblies and K for kitted hardware, and the same part often appears under several forms, such as 041A2817 and 41A2817. Search either way and you will find it.
If your model is not listed above, or the part you need is not on its page, call (866) 965-5599. We have been repairing these openers since 1993 and can usually identify a part from a photo or a description.
