Liftmaster 041B0990, DISPLAY CABLES KIT
The LiftMaster 041B0990 is a display cables kit for EL2000 Series telephone entry systems. These cables connect internal display-related components inside the access control unit. If a display cable is damaged, loose, or corroded, the system may have display problems even when the display or board itself is still usable.
This part is specific to the EL2000 telephone entry service-parts family and is commonly cross-referenced as 41B990. It should not be confused with 041B0997 interconnect board, 041B0705 20-pin cable, or CAPXL/CAPXLV cable assemblies. Cable kits should be matched to the exact system model and connector layout before ordering.
Common Replacement Reasons
Replace the display cable kit when the original cables are cracked, pinched, corroded, missing, or no longer hold securely in the board/display connectors. Intermittent display operation can also be caused by failing boards or power issues, so inspect the full system.
