## Questions & Answers

**Q: My garage opener model is 1265 -1/2HP. The logic part# in the manual is 41A5021-E. Will this logic board work with it? I cannot find the exact part #.**
A: The 41-5021-i will work for the liftmaster 1265 with the half horse motor

**Q: WOULD LOGIC BOARD #41A5021-I WORK WITH #1265?**
A: Yes. The Logic Board #41A5021-I worked perfectly in my Lift-Master Model 1265 1/2 HP garage door opener. If you can use a screwdriver you can replace it yourself.  It took my about 15 minutes to change.  I've been using the replacement for a couple of months now. Not a single problem. Good luck.

**Q: I have a raynor pilot 40A 5021-D  board I need to replace will this one for my door???**
A: The board might works but if it don't you will want to know if its free shipping and returns, be sure to 
take care of the board and not damage and if it don't work you can return the board.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Better, cheaper, and EASIER than installing a new system!
*by J***. on August 31, 2016*

Fixed the problem in about 15 minutes after lightning took out the old one. Replacement is super easy. Much, MUCH easier than replacing the entire door opener! Cheaper too. Instructions are included, but the process goes like this: Unplug the unit. Take off the light cover. (Lift up the bottom of the cover slightly and then pull straight out. Be careful because it can be a little snug and you don't want to crack the cover.) Remove the light bulb. Mark their locations and then disconnect the small wires from the 3 screw terminals. Remove the three screws that hold the cover to the unit. Disconnect the wire header connector and the assembly should come free from the unit. To install the new one first adjust the two potentiometers (mine were blue) to the same positions as the old ones. Then just reverse the above instructions and you're done with the worst of it. Program it for your remotes, test/adjust the door (including the safety features), and you're done. Total time I was in my garage to complete the repair was well under 30 minutes. I think the door operates a little smoother now too. Possibly because this is a newer version than the board I replaced. (Old one was an "F" model.) This board also works on some Craftsman door openers, but the plastic case is different on those. You'll have to transfer the new circuit board to the Craftsman case. That's about 5-6 screws, so add another couple of minutes to the install if you have one of those. Even people with low to moderate mechanical ability should be able to handle this with ease. If you're concerned about whether or not this board is the actual problem then consider this. There are really only two major parts inside of the unit, the motor and this board. Unless the motor has fried, which very unlikely, then this unit is your problem. There are some troubleshooting tips in your manual and on their website if you need additional help. PRO TIP: Get yourself one of those single plug surge suppressors to protect your opener so you don't have to do this again!

### ⭐⭐⭐⭐⭐ Fixed a 20+ yr old unit and made it work like new
*by P***S on December 24, 2022*

My old opener came with our house. Worked fine for 10 years and recently started giving us occasional issues (not responding to the remote). 2 weeks ago it stopped working all together - no response to the remote or the wired wall switch and the learn button was not lighting up when pressed.I called liftmaster and they were surprisingly helpful. They confirmed my diagnosis of a faulty logic board, and helped me identify a suitable replacement since the one in my unit was no longer manufactured.If you are reasonably handy this is an easy parts swap that will take 15 minutes to wrap up. It’s a PITA to do while balancing on a ladder but that’s not the parts fault.Worked as soon as I wired it up and plugged it in. Via the learn button I had my cars and other switches connected in 3 minutes. All good.Only issue is that subsequent fine adjustments were needed to the up/down force switches over the first few days to ensure the opener always went down properly. Installed on Monday, fine tuned on Tues/Wed, and all has been working properly since then.Saves a lot of money on a repair home visit and/or a replacement opener. No brainer solution if it can address your particular situation.

### ⭐⭐⭐⭐⭐ Exact OEM Replacement Worked Great
*by B***2 on December 28, 2022*

So my older, like vintage 1998, stopped working with our car remote. We purchased a new remote, no luck. So, I looked into buying a new circuit board. My old board ended with the letter "B", couldn't find a board with that designation. I started researching for compatibility and found a answer to a question on this issue and it noted all the boards that this board was compatible with, including the "B" version.I ordered this board and it was super easy to install, adjust the parameters of down force and finally yes, it now works with our remotes. Thank you for such an easy solution! Highly recommended.
