Sears Craftsman 139.53919D Receiver Logic Control Board
The Sears Craftsman 139.53919D receiver logic control board is a replacement logic board used on select Craftsman garage door opener applications with LiftMaster and Chamberlain service-board cross-references. It is commonly tied to the 41DB001-1 and 41DB101-1 board families.
This board is used when the original opener head is still worth repairing but the receiver logic board has failed. It handles remote-control communication, keypad memory, wall-control commands, and the main opener control logic for the matching unit.

Technician Note
Craftsman board numbers are easy to mix up because the opener model, housing number, and receiver board number may all be different. Use the printed board label as the main reference.
Before Ordering
- Confirm the Craftsman model number is 139.53919D or listed by the parts diagram.
- Confirm the original board references 41DB001-1, 41DB101, or 41DB101-1 style numbers.
- Confirm the opener uses 315 MHz Security+ radio accessories.
- Confirm the end panel and terminal layout match the original board.
- Reprogram all remotes and keypads after replacement.
Professional Advisory
If the opener has intermittent operation, inspect safety sensors, wall control wiring, door balance, and power before assuming the logic board is the only failed part.
Product Q&A
What Craftsman model is this board commonly used for?
This board is commonly associated with Sears Craftsman 139.53919D applications and related LiftMaster / Chamberlain service-board references.
Is 41DB001-1 the same as 41DB101-1?
These numbers are commonly cross-referenced in Craftsman replacement-board listings, but the original board label and opener model should still be checked before ordering.
What remote frequency should this board match?
This board family is used with 315 MHz Security+ systems, typically identified by a purple learn button on the opener.
Why did my remotes stop working after board replacement?
The receiver memory is stored on the logic board, so existing remotes and keypads need to be programmed into the replacement board.
Can this be used on any Craftsman garage door opener?
No. Craftsman openers use many different board generations, frequencies, and housings. This board should only be used on matching applications.
