Liftmaster LA500PKGU Replacement Control Board K1D8388-1CC /LA500

Worked great

If you are replacing an older board with this newer one, make sure you are using the Liftmaster photo eye entrapment device FROM LIFTMASTER. These devices exchange diagnostic data and an aftermarket or older eye will issue an error code 60 indicating no entrapment device is connected. The aftermarket photo sensor can be used as a secondary device. The Liftmaster photo sensor is ridiculously priced (nearly as much as the board). The board itself has great functionality but, could be fused better between the batteries and the board. The 30 amp fuse is too high for a 7 amp battery. If your battery shorts (occasionally old ones do) it can short the system as the batteries do not go through the power conditioner on the transformer (as you might expect). The solution to this is for Liftmaster to separate the battery connector harness from the power connector harness and fuse separately or lower the over all fuse amperage to better protect the lower amperage system. You should check your batteries annually for signs of leakage, swelling, frayed wires or insect infestation. Also ensure the external antenna is not grounding out on a fence or other metal object.

This was an newer version of the same board I needed for my gate. Having installed the original gate system, the instructions were of similar (good) quality.
