When your garage door opener system begins to malfunction, it’s important to fix it immediately. A faulty system is not only frustrating, it is dangerous. Fortunately, fixing your system may be easier than you think. If your system isn’t working properly, you may not need to replace the entire opener unit. As the brain of the system, a properly functioning circuit board is vital for a properly functioning system, and an unresponsive keypad, remote or sensor may all be due to a faulty circuit board.
At North Shore Commercial Door, we carry every type of circuit board for Chamberlain LiftMaster garage door opener systems. The LiftMaster Chamberlain 41D4674-10H Logic Board is compatible with many screw drive models and can work interchangeably with many other logic boards, including model numbers:
• 14LG0607B (number printed on some units)
Replacing your circuit board is not only an inexpensive fix, but it is also a simple one. In most cases, there’s no need for a repair man. To help ensure you replace your circuit board safely, it is important to make sure there is no power going to your system, and it’s a good idea to have someone assist you with the replacement. For detailed steps on how to safely replace your circuit board, please visit our comprehensive list of Product Manuals.
In most cases, a faulty circuit board is due to power surges or lightning strikes. When you do replace your circuit board, we suggest using a 990LM Garage Door Opener Surge Protector as a safeguard against future power surges.

QUESTION: I have a liftmaster 2000 sdr opener and all of the remotes work sporatically. I have changed batteries and even bought a new remote. Does this sound like a board failure? When it works, the door goes up and down like normal. I reprogrammed the remotes and they still work sporatically. by David L 8/24/2016
ANSWER: I had the same issue, the wired control on the wall worked fine, but remotes were intermittent and then didn't work at all. I tried new batteries, re-programming in several different ways, even a new remote, all to no avail. I felt I had exhausted all other options so I called Northshore Door nice people and reviewed the symptoms. They can't diagnose an opener over the phone of course but I wanted to see if they had any other suggestions- they didn't. I ordered the board online, it came right away, I installed it by following the simple instructions included and the opener has worked just fine ever since. I have one car with a built in remote that I still can't program but it might be the car since all of the remotes work. These are very common openers and there is a lot of info out there, if you eliminate every other cause then buy the board, they fail pretty frequently. If there are any other issues with your unit consider a new one, they are fairly robust but this is an old model, and anything mechanical wears out eventually. The next time I have issues with mine I'll replace it. Good luck! by Norman B a
ANSWER: It could be the board. That sound like what I went through, but our door would open by itself. A couple of things to check. Did you install an LED light anywhere near the motor? LEDs can interfere with the signal. Also how old is your opener? If it is 15-20 years old you might just want to get a new motor/ opener assembly. The board I purchased didn't fix the odd behavior so I just got a new motor/ opener. So I ended up spending more in the long run as well as wasting a lot of time. by Timothy C a
ANSWER: I don't know if that is your solution. But I experienced the same problem, leap of faith and ordered the new board. The new board fixed my problem. by Joseph J a
