Genuine LiftMaster 041A5021-1HATS receiver logic board (also 41A5021-1HATS) — the 390 MHz Security+ rolling code board with the red / orange learn button for the LiftMaster ATS211R and ATS211X light-duty trolley operators. It is not the board for the 315 MHz ATS2113X, which takes the 041A5021-9G-315, and the similar-looking residential 41A5021 boards are not substitutes — the ATS version has its own connector layout.
Red or orange learn button = 390 MHz = this board. Unplug the operator and remove the cover; the number is printed on the board. A purple learn button means the 315 MHz ATS2113X and the 041A5021-9G-315. The original ATS and ATS211 boards are discontinued with no replacement.

Check the capacitor before the board. An ATS that hums and does not move is almost always the K030B0532-1 capacitor; one that runs a few inches and stops is usually the 041C4398A RPM sensor or the limit switches.

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 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, motor hums but the door does not move | The capacitor on an AC unit, or a stripped drive gear. Not 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 and RPM sensor. The board only after those |
| 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.
