LiftMaster Garage Door Opener 41A5021-5I Receiver Logic Board

Our garage door was gradually not working all of the time over a period of months. First I bought new remotes which worked for a week but gradually stopped working. It only worked with the wall mount control. After troubleshooting on internet I decided to try the new logic board. Easy to install and worked immediately. Worth every penny. Thank you Amazon and your reviews. Satisfied customer!! Oh and our garage door opener is 18 years old. A Liftmaster.

Just make sure you get the right one for your opener (Hint... The color of the learn button is the key). Super simple fix... Unplug the power cable from the outlet. Remove 4 screws. Take the wires from your sensors and wired remote that are screwed to terminals 1,2, and 3 and label which ones go to which terminal. Unplug one large multi-pin connector from the board (easier than it sounds...). Attach connector to new board, install 4 screw to mount it, re-attach the wires you removed from terminal 1,2 and 3 and plug the power cable back into the outlet. Press the learn button on your opener, press and hold the button on your opener to re-pair it. Go have a sandwich. Done. Range is just as good as the old one before it failed and started to not receive signals (after 21? years).

I had ordered the logic board for my aging Chamberlain garage door, to fix a problem with it not working with the remote controllers. The board arrived and it took all of about 15 minutes to replace. Reprogrammed the controller and it has been working perfectly. Many thanks for the prompt delivery!

I'll explain very briefly. I was having a problem opening our garage door from a distance. While inside I could open it with clicker in hand but when outside with garage door close It wouldn't work. A little frustrating cause I had to get out of car and lift it open every time while waiting for product to come in mail. Installation was super easy. When it came I removed the thin wire and soldered a thicker and longer wire. Now I can come from a block away and click it and the door will be opened when I pull in. It works fantastic.

This is a great replacement for my garage logic board. Really easy to replace, just unplug some wires, unscrew, and replug back. No smoldering required. Works great if your problem is remotes no working consistently anymore or losing range. It was taking mult long clicks to close garage, now super snappy.

I was looking for a replacement logic board for my older Liftmaster 1995 and found out that it's discontinued, attempted to use this model and it works great, installation was a breeze

I live in Florida and had lightning kill the logic board of my garage door opener. I was faced with full replacement, or installing this board myself after watching a YouTube video. It was fairly easy to install, and was the affordable answer.

Our remotes for our 19 year old opener was opening the door, but couldn't close it....most of the time. I suspected something in the board died, but Chamberlain support suggested wall button replacement. After doing this and after about 3 minutes of false hope, the problem resurfaced. So I bought and installed the board (easy easy) double checked the reversal feature, reprogramed the remotes and cars and all is good again. Note, we've got three openers and we replaced the board on one of the others about 4 years ago when it too was operating inconsistently. Much more cost effective than replacing the opener. Opener 3 is still alive and well. Two repairs over 57 opener-years - I can't complain.

Thank you!
