The LiftMaster 41B7611 Filter Board is a genuine OEM replacement component used inside select LiftMaster garage door openers to suppress electrical noise and help ensure stable operation of the control electronics and radio receiver. This filter assembly mitigates electromagnetic and radio-frequency interference generated on the power and motor circuits, supporting reliable remote control performance and reducing interference-related issues in residential garage applications. It is intended as a direct replacement for the original filter board in models that specifically list 41B7611 in their parts diagram or service documentation.
Designed for plug-in compatibility with the factory harness and mounting points, the 41B7611 typically installs within the opener chassis near the power input and motor wiring. No programming is required for the filter board itself; however, always disconnect power before servicing and follow the opener’s service manual for model-specific procedures. For best results and to confirm fit, verify your opener’s exact model number and parts list prior to purchase, as this filter board is only compatible with units that call out 41B7611 as the correct replacement. This OEM part is an ideal solution for maintenance or repair when restoring reliable performance to compatible LiftMaster openers.
Compatible with LiftMaster 8360 and 8550 models
