Frequently Asked Questions
Which logic board do I need for my LiftMaster or Chamberlain opener?
Find three things: the learn button color, the drive type (chain, belt, screw or wall mount, AC or DC) and the year. LiftMaster's logic board conversion chart uses those to name the current replacement. For example, yellow learn button DC chain and belt openers made 2011-2023 take the 045DCT, and purple learn button AC screw drives take the 41AS050-1. Call us with your model number if you're unsure.
What do I need to do after replacing a logic board?
A new board arrives blank. Set the travel limits and force, program your remotes, keypads and HomeLink again, and test the safety reversal. On a Wi-Fi opener, add it to the myQ app again.
Can I put a newer board in an older opener?
Not usually. LiftMaster lists boards by learn button color and drive type; a Security+ 3.0 (white learn button) board such as the 030DCT doesn't upgrade older openers. Green learn button openers (1993-1995) are no longer supported, and most red/orange learn button boards are discontinued.
