The LiftMaster K1D8247 hall effect sensor board is a board-style movement feedback component used on select CSW200U swing gate operators. It helps the control system read gate movement or position feedback, which is important for proper travel monitoring and operator response.
This part is typically considered when the operator has hall effect sensor faults, inconsistent movement feedback, or diagnostic behavior that points to the sensor board. Before replacing it, the technician should inspect the harness, connector pins, sensor mounting, control board input, and mechanical drive components. A sensor fault can be caused by wiring or mechanical problems, not only by the board.
K1D8247 is commonly tied to CSW200U and related CSW200UL references. It should not be mixed with hall effect sensor kits used on slide gate operators or older SW420 applications.

Do not assume a board-style sensor failure until wiring, connectors, target condition, operator drive condition, and board inputs have been inspected. A loose harness can create the same symptoms as a failed sensor board.
CSW swing gate operators use high-force moving hardware. If the gate is binding, moving unpredictably, or showing safety faults, have a qualified gate technician diagnose the system before replacing electronic parts.
It provides movement or position feedback for select CSW200U swing gate operators so the control system can monitor travel.
It is commonly listed for LiftMaster CSW200U, with CSW200UL appearing in related references when confirmed by parts diagram.
No. It is a hall effect sensor board, not the main operator control board.
No. K74-G0589 is a different hall effect sensor kit used on select slide gate operators.
Check the harness, connectors, mounting, target area, mechanical drive condition, and control board input before replacing the sensor board.
