The 2565 is a chain drive opener. Everything for it is on this page: the motor unit, the gear and sprocket, the rail and chain, the safety sensors, the door hardware, the wall control and the remote. Each section has its own diagram, and the reference numbers are specific to the diagram directly above them.
Motor runs but the door does not move? On these openers that is almost always the gear and sprocket assembly — the nylon gear strips. It is part 041C4220A, also listed as 41A2827, and we stock it in both factory and aftermarket versions. See section 2.

Refs 09 and 17 are not stocked separately. The cover here is the plain 41A5525 — the 041A5525-1 is a different opener's part, so check the number before ordering.
Motor and logic board. The ref 11 motor and bracket assembly (41C4842-2) and the ref 18 receiver logic board (041A5483C) are both discontinued and we do not currently stock a replacement for either. Every other part on this diagram is available. If your 2565 has a failed motor or board, call (866) 965-5599 before ordering anything else — we can tell you whether a repair is still worth doing or whether a new opener is the better spend.
The nylon gear on the 041C4220A is the most common failure on these openers, and the part fits most LiftMaster chain drives. You may see it called 41A2827 — it is the same assembly. If the motor runs and the door does not move, this is what to order. We stock both the genuine LiftMaster assembly and a lower cost aftermarket version built to the same dimensions.
| Part # | Description | Factory (OEM) | Aftermarket |
|---|---|---|---|
| 041C4220A | Gear and sprocket assembly, aka 41A2827 | Factory assembly | Aftermarket assembly |
Fit the new gear with the opener disconnected from the door, and grease the worm before reassembly — running it dry is what strips the next one. The 041A2817 gear kit is the alternative if only the gear itself has failed.

The chain assembly is sized to your door height. Measure the door opening, not the rail. A slack chain can usually be re-tensioned rather than replaced — replace it if links are stiff, the cable is frayed, or the chain has jumped the sprocket. Browse all chain and master links.
