I have a Craftsman door opener. It keeps forgetting my programable remotes. The wall remote always has its light blinking which indicates it needs to be programed. I program it and the light still blinks but the door works for a while then forgets again. I has the green button on the side for programing the remotes.

Try a process of elimination:
Disconnect the wall unit and see if the hand units' programming still gets lost.
If not, the problem is in the wall unit. If so, you've eliminated the wall unit as the culprit.
Next, try using only one, then the other of the hand units. If the programming stays put when only one or the other is used, then the failing one has been defined.
Still got the problem? That just leaves the main box. Sounds like it may be a power problem, either to the box, or inside it.
Shut power off, open it up, and check all connections that you can.
Still no good? Either replace it or get a pro repair.

Hi, I haven't looked at any of the newer units but what you're describing makes me wonder if the main unit has some sort of backup battery to hold the codes in memory? The old opener units used DIP switch settings to program the remotes and the main unit.

If this unit is programmable, then maybe there's a backup battery somewhere that needs changed. Otherwise, any time the main unit lost power, the memory would dump and the unit would have to be reprogrammed to recognize the remotes. It may be something like a 9V battery, or it could be a couple D cells, etc. If you have the manual for the unit, see if it mentions a backup battery.

I hope this helps some. Regards! Jim D/Heathsville, VA
