Liftmaster 041B0997, INTERCONNECT BOARD
The LiftMaster 041B0997 is a replacement interconnect board for EL2000 Series telephone entry systems. In a telephone entry unit, the interconnect board helps link internal components so keypad, display, communication, and control functions can work together. If this board or its connectors are damaged, the system may show intermittent behavior, communication issues, or component connection problems depending on the failure.
This part is specifically associated with LiftMaster EL2000 systems and related 41B997 references. It should not be used as a substitute for CAPXL boards, EL25 cables, display cable kits, or other telephone entry electronics. Since access control boards can be non-returnable after installation, confirming the original board number before ordering is especially important.
Common Replacement Reasons
Replace the interconnect board when it is physically damaged, corroded, missing, or confirmed faulty after checking cables, connectors, power, and the connected assemblies. A loose display cable or power issue can look like board failure.
