A malfunctioning garage door opening system can put your household at risk. Not only is a faulty system an inconvenience, a malfunctioning safety reverse system can be extremely dangerous, especially when small children are involved. If your remotes or keypads have become unresponsive or if you sensors have become inconsistent, you may not need to replace the whole system to restore functionality. These issues are commonly caused by a faulty circuit board. Fortunately, replacing your circuit board is inexpensive, and in most cases, can be installed without the aid of a professional.
The Chamberlain 45ACT LiftMaster logic board is compatible with a number of LiftMaster models. Equipped with a Learn button, the 45ACT circuit board is not only simple to install, it is also simple to program the remote controls and adjust the travel and drive controls. For step-by-step instructions regarding installing, programming and adjusting your LiftMaster logic board, please reference your model’s owner manual, many of which can be found in our comprehensive catalog of Product Manuals.
