Technician Note
The 41DB001 family is frequency and generation specific. A board that fits the housing may still be wrong if the learn button color, opener family, or manufacturing range does not match.
Before Ordering
- Confirm the opener is a matching LiftMaster or Chamberlain DC belt drive model.
- Confirm the original board belongs to the 41DB001 / 041DB001-1C family.
- Confirm the opener uses a purple learn button and 315 MHz Security+ accessories.
- Take a picture of the existing wiring before service.
- Reprogram remotes, keypads, and vehicle buttons after replacement.
Professional Advisory
If the original board shows burn marks, water damage, or repeated failures, inspect the opener, outlet, wiring, and accessories before installing a new board.
Product Q&A
41DB001 is part of the same commonly referenced service-board family as 041DB001-1C. Match the original board number and opener model before ordering.
Is this board for a 3500 opener?
This board is commonly associated with LiftMaster 3500-series DC belt drive applications when the original board and end panel match.
What frequency does this logic board use?
This board family is used with 315 MHz Security+ systems and a purple learn button on matching openers.
Will this board keep my programmed remotes?
No. The receiver memory is on the board, so remotes, keypads, and vehicle buttons normally need to be programmed again after replacement.
Can I use this on a yellow learn button opener?
No. Yellow learn button Security+ 2.0 openers use a different control-board platform and this 315 MHz purple learn button board is not interchangeable.
