Liftmaster 041B0705, CABLE, 20 PIN
The LiftMaster 041B0705 is a 20-pin internal cable assembly for select LiftMaster access control and telephone entry equipment. This type of cable carries signals between internal boards or control modules, so a poor connection can cause display, keypad, communication, or board-to-board issues depending on the system design. While the cable may look like a standard ribbon or multi-pin harness, it should be matched by LiftMaster part number and system parts diagram.
Several catalog references describe 041B0705 as a replacement 20-pin cable for LiftMaster telephone entry systems, with EL25 and CAPXL-related parts references appearing in different listings and service-parts material. Because of that, the safest fitment approach is to verify the system model and the parts breakdown before ordering. Do not assume any 20-pin cable from another access control unit will be interchangeable.
Common Replacement Reasons
Replace this cable when the original 20-pin harness is cut, pinched, corroded, missing, or has damaged connector ends. Intermittent display or board communication issues can also be caused by a loose or damaged cable, but the boards and power supply should be checked before replacing parts blindly.
