Genuine LiftMaster 041DB001-1C receiver logic board with end panel (printed 41DB001-1; also 41DB001, 41DB001-6, 041DB001-1) — the 315 MHz Security+ board with the purple learn button for the 2005–2015 LiftMaster and Chamberlain DC belt drive openers with battery backup: the LiftMaster 3500, 3500C, 3500D and the Chamberlain WD952KD, WD952KLD, WD952KCD, WD952LD and HD800D. Sold as a kit with the end panel.
Purple learn button, DC motor, separate power supply = this board. The number is printed along the edge of the board behind the end panel. Do not order from the model on the label: the 2500, 2500B and 2500D look the same but used different boards, and none of those are made any more.

Which openers use the 041DB001-1C
| Opener | Parts page |
|---|---|
| LiftMaster 3500, 3500C, 3500D (DC belt, battery backup) | 2500 / 3500 parts |

Not for the 2500 family, and not for AC openers. The original 2500 board and the 041A5507-6C fitted to the 2500B and 2500D are discontinued with no replacement — call us before ordering anything else for one of those. The AC belt drives of the same years (WD822KD, WD832KD, HD600) take the 041AB050-2M. The later Chamberlain HD800 (AC, Wi-Fi) takes the 050ACTBMC.
Parts often replaced with it
On this platform a dead opener is often the power supply or the fuse rather than the board, and both are cheaper. 041B5351-7 power supply · 041C0168 transformer · 041D0605-1 motor · 041B0591 backup battery · 41A5726 battery backup board · 373LM remote
Is the board actually the problem?
The logic board is the most over-ordered part on a garage door opener. Work down this list before you buy:
| Symptom | Check first |
|---|---|
| Opener dead, but the power supply LED is out too | The 041B5351-7 power supply and its fuse before the board |
| Opener completely dead — no light, no beep, nothing from the wall button | The outlet and breaker, then the line cord and the transformer. The board is last on this list, not first |
| Light comes on but the motor does nothing, or clicks once | On these DC units the motor and travel module, then the wiring between them and the board |
| Door will not close and the opener light flashes 10 times | The safety sensors — alignment, a cut wire or a sun-blinded eye. This is never the board |
| Remotes and keypad stopped working but the wall button works | Remote batteries, then re-program them to the learn button. Only if the learn button LED never lights is the receiver on the board suspect |
| Lost its Wi-Fi or myQ connection | The router, the phone app and the Wi-Fi signal in the garage — not the board. Re-run the myQ setup from the app before ordering anything |
| Runs a few inches and reverses, or stops short of the floor | Door balance and the travel and force settings first, then the travel module. The board only after those |
| Beeps every few seconds, or runs slowly on battery | The backup battery is a consumable — replace it before suspecting the board |
| Learn button LED never lights, opener runs one way only, or it failed the night of a storm | The board. Surge damage is the single most common reason one of these is replaced |
After fitting
The replacement board arrives blank. After fitting it you will need to set the travel limits and force, program every remote, keypad and vehicle HomeLink to the new learn button, and re-test the safety reversal on a 2x4 laid flat on the floor.
Put the opener on a surge protector when you fit the new board. Lightning and utility surges are the most common reason a garage door opener logic board is replaced, and a new board on the same unprotected outlet is at the same risk. A plug-in surge protector rated for motors is a small cost next to a second board.
Common questions
My board says 41DB001-1. Is the 041DB001-1C the same?
Yes. 41DB001-1 is printed on the board; 041DB001-1C is the number of the boxed service kit, which includes the end panel.
Will it work with my 893MAX / 890MAX remotes?
Yes — the tri-band remotes cover 315 MHz. The older 371LM / 373LM 315 MHz remotes also work; 390 MHz 971LM / 973LM remotes do not.
Is this the board for my 2500D?
No. The 2500D used the 041A5507-6C, which is discontinued. Call us before spending on parts for a 2500 with a dead board.
