Product Description

This replacement circuit board, part number 41AC050-1M, fits several LiftMaster Chamberlain garage door openers and is identical to earlier circuit boards with the 41AC050-1 part number. The final letter designates a model year change, so as long as the rest of the part numbers are the same, the circuit boards are interchangeable.

A bad circuit board is a common cause of problems with garage door openers, and replacing a faulty board with a new one from North Shore Commercial Door is a quicker and less expensive fix that replacing the entire unit.

This replacement circuit board fits the following LiftMaster Chamberlain models:
