The LiftMaster 41B0736 is a service replacement board for select LiftMaster telephone entry and access control systems. This part is used inside the entry system cabinet to restore the specific board function identified by the original part number and system parts diagram. Because EL-series telephone entry systems use multiple circuit boards, this part should be ordered by the original board label, board function, connector arrangement, and system model rather than by appearance alone.
This board is most commonly associated with LiftMaster EL25 and EL2000 telephone entry systems. In the field, these systems may be used at residential communities, gated properties, commercial entrances, shared access points, and controlled vehicle entry locations. Replacement may be considered when the board has failed due to age, surge damage, corrosion, water intrusion, keypad/display communication faults, input/output problems, relay trouble, or visible board damage, depending on which board is being replaced. This is the input-board style component and should not be confused with the main processor board, output board, or LED board used in the same EL-series cabinet.
The 41B0736 board is commonly associated with the following LiftMaster telephone entry systems and board families. Compatibility should be confirmed by the original board number and parts diagram.

Telephone entry circuit boards are sensitive to voltage problems, surge damage, corrosion, and incorrect wiring. Photograph the original board wiring and connector positions before removal. If the old board shows burned traces, water damage, or repeated surge failure, inspect the enclosure, power supply, grounding, phone-line protection, and accessory wiring before installing the replacement board.
This is an electronic access-control part. Disconnect power before servicing, avoid shorting terminals, and do not bypass access-control or gate safety circuits to test the system. If the telephone entry system controls a gate operator, verify safe gate operation and access-control behavior after service.
The LiftMaster 41B0736 is a replacement input board used in compatible LiftMaster telephone entry and access control systems, especially EL25 and EL2000 style systems where the parts diagram calls for this board.
Yes. This board family is commonly associated with LiftMaster EL25 and EL2000 telephone entry systems, but the exact board position and part number should be matched to the system parts diagram.
It may help when the failed function is on this specific board, but power supply, wiring, keypad/display boards, relays, surge damage, and phone-line issues can create similar symptoms.
Some telephone entry boards may require setup, wiring confirmation, or system testing after replacement. Keep the original wiring layout documented before removing the old board.
Check the model number, original board label, connector locations, ribbon cables, wiring, power input, and any visible surge or water damage before installing the replacement board.
