Chamberlain PD210D & PD212D Chain Drive Parts
Chamberlain PD210D and PD212D Replacement Parts
These are chain drive openers. Each section below has its own diagram and its own reference numbers — the numbers in a table match the diagram directly above it, not the other sections.
Motor runs but the door does not move? On these openers that is almost always the chain drive gear and sprocket kit at ref 2 — the nylon gear strips. Grease the worm before fitting the new one; running it dry is what strips the next.

The original 950ESTD and 953EV-P2 remotes are discontinued. The 893MAX is the universal replacement and works with all the older Chamberlain, LiftMaster and Craftsman openers. If your sensor brackets are bent or missing as well as the eyes, the 041-0365-000 includes both and works out cheaper than buying them separately.
