Blue - Replacement for All Versions of Generation 1
The Generation 1 Control Board is compatible with the light gray LiftMaster LA500 arm, see the blue control board visual below. This serves as a replacement board for all the boards within Generation 1, which were manufactured prior to July 2014. The Generation 1 Control Board is not compatible with MYQ technology and it does not have a digital display. Therefore, the LiftMaster LA500 light gray arm is not compatible with the Generation 2 or 3 board.
If you are replacing a generation 1 control board (It is easy to tell, the old LiftMaster board is blue and the new one is green), you will need new MAX series remotes and keypad to replace your current LiftMaster products. You can also purchase a 312HM Receiver to utilize your current remotes and keypads.

If you are replacing a Generation 1 Control Board you will need to replace the whole control box, as well remotes and accessories.
