The LiftMaster 050DCJCWFRD Logic Board is an OEM replacement control board engineered for select LiftMaster DC jackshaft door operators. As the operator’s main control module, it manages motor direction, travel limits, force settings, wall control inputs, safety device monitoring, and radio control memory. Replacing a failed logic board can restore normal operation for commercial or light‑industrial jackshaft systems commonly used on sectional doors, rolling doors, and grilles. This factory part is designed to integrate with the operator’s existing wiring harnesses and safety accessories, providing reliable door control when the original board has been damaged by power events, environmental factors, or wear.
Verify compatibility by matching part number 050DCJCWFRD to the operator’s model-specific parts list, service manual, or the original board label before ordering, as logic boards are not interchangeable across all models. Installation should be performed with the unit disconnected from power, transferring wires one‑for‑one from the old board to the new board to avoid miswiring. After replacement, reprogram travel limits and any required settings, then test all entrapment protection devices per UL 325 procedures to confirm safe operation. For best results, have a qualified door professional handle setup and programming.
