LiftMaster 41A5021-9G-315 Replacement Receiver Logic Board for ATS (315MHz)

Upgrade your LiftMaster ATS system with a genuine receiver

For LiftMaster garage door openers produced 1997–2005, the 315MHz Security+ receiver logic board is a key interface between remote signals and the opener. This replacement kit gives you a path to restore responsive control when the original receiver shows signs of wear.

The complete kit includes a 315MH logic board, an end panel, and a door control. The purple learn button provides a clear setup cue during pairing, a familiar feature for installers and homeowners replacing older parts.

Genuine LiftMaster parts are designed to fit with the ATS2113 family, maintaining expected performance and avoiding fit issues that can come with aftermarket options. The 315MHz frequency supports common remotes used with these units, preserving your existing remote ecosystem.

Before you order, check the part diagram or the manual for your opener to confirm compatibility with your specific unit. The listing notes that this kit does not replace other 41A5021 variants, so a quick cross-check helps ensure a smooth swap.
