I got 41A5021-I board assembly. It has different housing than 41A521-4F, but circuit board from 41A5021-I fits perfectly in old 41A521-4F housing. Just have to unscrew/screw 4-5 screws, and connect the lamp socket. It works just fine with almost 20 years old garage opener.

As mentioned in the disclaimer, I did have to remove the board from the housing. Switched out the board with the old housing. Now my opener is working, but not as well as it used to. My remotes are now working most of the time within very close range. I have to hold the button down on the remote for a few seconds, only when I'm right up on the garage door. I believe I need to play around with the transmitter wire, maybe replace that with a longer one.

I replaced my garage door’s logic board a few weeks ago and since then the issues I had with garage door openers not working when the light was on have gone away. As mentioned on the site, the housing for the new logic board didn’t match exactly (my old one had screws at each corner but the new one only had 3). I could have just screwed in two corners, but it was easy enough to just switch the logic boards so I had the new logic board in the old housing that actually fit my opener. Took about 30 minutes including reprogramming remotes, and a fraction of the cost of a new garage door opener or to have a professional do the same repair.

This logic board was a replacement for our craftsman garage door opener that quit working because the transmitting signal would not relay to any of the opening device, only the hard wired opener would work. It was easy to install and solved the problem. The mounting holes for the new board were not aligned with the mounting holes from the old housing, probably because it was manufactured in 2002, but we didnt find this to be a problem. The solution was to drill new holes in the housing case. I would recommend this part to replace logic board as opposed to getting a whole new garage door opener.
