LiftMaster Chamberlain 41A5021-3 Circuit Board with Red Learn Button – Compatible Motors and Interchange Numbers.
NOTE
Not compatible with commercial or semi-commercial Openers.
When purchasing a logic board, you may notice different characters at the end of the part number (e.g., 41AB050**-2**, 41AB050**-2M**, or 41AB050**-2G**).What they mean: These suffixes simply indicate the manufacturing date or hardware revision (such as a different brand of relay or a minor update to the circuit board layout).Compatibility: The suffix does not change the functions of the board. All boards within the 41AB050- series are 100% interchangeable and will work perfectly with your existing 315 MHz system.The Golden Rule: As long as your original board has the Purple Learn Button, any board from this series will be a direct, "plug-and-play" replacement regardless of the suffix.
The garage door opener consists of multiple components that could be contributing to the issues you're experiencing. Consequently, even if you replace the circuit board, the motor may still exhibit the same behavior. If this occurs, please reach out to me for assistance in troubleshooting the problem, please don't jump to the conclusion that the board you have received is defective.
