Motor runs but the door does not move? Check the 041A2817 gear kit at ref 03 — the nylon gear strips and that is the usual cause. If the opener hums but nothing turns at all, it is more likely the capacitor or the motor.
1. Garage Door Opener Repair Parts
First part of number below corresponds to diagram number above:
| Ref | Part Number | Description |
|---|---|---|
| 03 | 041A2817 | Gear kit — drive and worm gear with grease |
| 04 | 041B4245-1 | Line cord, 6 ft |
| 08 | 041C0279 | Light socket |
| 12 | 041A3150 | Terminal block with screws |
| 13 | 041D3058 | Universal replacement motor and bracket assembly, 1/2 HP |
| 15 | 041A2818 | Limit switch drive and retainer |
| 16 | 041D3452 | Limit switch assembly |
| — | K030B0532-1 | Capacitor |
| — | K012A0373 | Capacitor bracket |
| — | 041A2770-17 | Installation hardware kit |
If the door stops at the wrong point or will not travel fully, the limit switch assembly at ref 16 or its drive gear at ref 15 is the usual cause. The 041D3058 motor is a universal 1/2 HP replacement and fits a wide range of Chamberlain and LiftMaster openers.
2. Chain, Rail and Trolley
| Ref | Part Number | Description |
|---|---|---|
| — | 004A1008 | Master link kit |
| — | 041A3473 | Chain and cable — 7 ft door, T rail |
| — | 041C2760 | Chain and cable — 8 ft door, T rail |
| — | 041A3489 | Trolley assembly — T rail |
| — | 83A11-2 | Rail grease |
The chain is sized to your door height — measure the door opening, not the rail. A slack chain can usually be re-tensioned rather than replaced. If your opener runs a belt rather than a chain, see the Chamberlain belt and rail parts page instead.
3. Safety Sensors and Brackets
| Ref | Part Number | Description |
|---|---|---|
| — | 041-0136 | Safety sensor eye kit — replaces 41A5034 |
| — | 041-0155-000 | Safety sensor brackets, 2021 to present |
| — | 041-0365-000 | Sensor eyes and brackets — the complete set |
| — | 041B0873 | Sunblocker bracket — stops sunlight false-tripping the eye |
| — | 041B4494-1 | 2 conductor bell wire, 26 ft |
Safety sensors became a legal requirement in 1993, so the earliest openers in this range may not have them. If yours does, the current 041-0136 eye kit replaces the older 41A5034 and fits Chamberlain and LiftMaster openers alike.
4. Door Hardware and Remotes
| Ref | Part Number | Description |
|---|---|---|
| — | 041B0035B | Curved door arm |
| — | 4178B0034B | Straight door arm section |
| — | 041A8094 | Door arm kit — curved and straight sections together |
| — | 041A2828 | Emergency release rope and handle |
| — | 893MAX | 3 button remote control — universal replacement |
| — | 041C0494-2 | Multi-function door control panel |
These openers predate Security+ 2.0, so use the 041C0494-2 wall control rather than a MyQ panel — the modern panels will not work. The 893MAX replaces every older Chamberlain, LiftMaster and Craftsman remote. Browse all Chamberlain remote controls.
