Liftmaster 041A5629-2A, RECEIVER LOGIC BOARD, 390MHZ

The LiftMaster 041A5629-2A is a 390MHz receiver logic board with end panel. It serves as the main receiver/control interface for select LiftMaster and Chamberlain garage door openers from the red/orange learn button era. The board receives compatible remote and keypad signals, controls opener operation, and provides the end panel interface used on the matching opener head.

This board should be ordered by the exact part number, learn button color, frequency, and opener model. LiftMaster used multiple 390MHz, 315MHz, and later Security+ 2.0 board families over the years. A board that looks similar can have different radio technology, terminal layout, end panel style, or compatibility with remotes and keypads.

• Confirm the opener uses a red/orange learn button and 390MHz remotes
• Inspect for surge damage, burned traces, or water intrusion before replacing the board

Important Ordering Warnings

• Do not replace a 315MHz purple learn button board with this 390MHz board
• Do not replace a yellow learn button Security+ 2.0 board with this part
• Power must be disconnected before removing the end panel or logic board
• If lightning or surge damage is suspected, other accessories or wiring may also be damaged

Professional Advisory

Logic board replacement involves electrical connections and programming. A qualified garage door technician should handle the repair if wiring is damaged, the opener behaves unpredictably, or the board failure may be related to a power surge.
