Product Description

A malfunctioning garage door opener system is not just an inconvenience; it can be a danger to you and your family, especially if young children are involved. Fortunately, replacing your garage door opener system’s circuit board may be a simple fix, saving you time and money. Many times, a replacement circuit board can restore your system, preventing you from having to replace the whole system. At North Shore Commercial Door, we carry replacement circuit boards for every type of Chamberlain LiftMaster model system.

A popular replacement for many LiftMaster logic boards manufactured between 1997 and 2005, the LiftMaster 41A5021-I is simple to install, program and adjust. The 41A5021-I circuit board can replace LiftMaster part 41A5021-F and the LiftMaster 41A5021-D board. In addition, the 41A5021-I circuit board can also replace model numbers:
41A5021
41A5021-B
41A5021-C,
41A5021-E,
41A5021-G
41A5021-H

To ensure your replacement 41A5021-I circuit board is compatible with your system model or can replace your current circuit board, please reference our Chamberlain LiftMaster Circuit Board Compatibility Chart.

In most cases, replacing your circuit board is a simple process, and there is no need to seek professional assistance. Once installed, programming and adjusting your system are also a simple process. It is important to always check your safety reversal system multiple times after you replace your circuit board. For detailed instructions on installation, programming and adjusting, please reference the 41A5021-I Product Manual.

Most faulty circuit boards are caused by power surges and lightning strikes. For this reason, we suggest using a 990LM Garage Door Opener Surge Protector to prevent future problems with your replacement circuit board and ensure you system continues to operate correctly.

QUESTION: My who unit is probably almost 14 years old. My outside keypad doesn't work ...or light up with new battery ...my remote only works sometime, but rarely and it's not the battery. Should I replace the circuit board or the whole thing at this age? by Trish V 7/9/2014
ANSWER: I replaced the circuit board, and while it did result in like-new performance it was quite a job.<br />The wires are pretty short and not easy to disconnect and reconnect again, especially while working in place. My unit had no headroom which made it difficult. Then, you have to reprogram the unit and remote. It was all very tricky and tedious.<br />So, it does work but it was a lot more trouble than it appears to be. The customer service dept at Chamberlain was very patient and helpful, so that was a welcome surprise. Good luck! by anthony b a

ANSWER: My unit is the same age. Our hard wired wall button worked fine but all of our remotes started working intermittently at the same time.
