Where is the reset button located on a LiftMaster garage door opener?

The reset button on a LiftMaster garage door opener is typically the Learn button, which is used to reset and reprogram remotes and erase memory, and is located on the opener motor unit itself. For most LiftMaster models, Learn button is on back or side of motor unit that hangs from ceiling, near antenna wire and light cover, often under light lens that you need to remove to access, and its color indicates technology: yellow Learn button for Security+ 2.0 rolling code from 2011 onward, purple for 2006-2014, red or orange for older models, and green for Billion code. Pressing and holding Learn button for 6 to 10 seconds until LED goes out erases all remotes, keypads, and MyQ devices, effectively resetting opener memory, after which you reprogram remotes by pressing Learn briefly and pressing remote button within 30 seconds. Some LiftMaster models have separate red or black reset button near Learn button that resets logic board when pressed. Wall consoles have lock button that can be held for 5 seconds to reset lock mode that disables remotes. To fully reset logic board after power outage or malfunction, unplug opener from power outlet for 30 seconds then plug back in, which power cycles board. Refer to your specific LiftMaster manual, as location varies by model like 8355W, 8587W, or 8500W jackshaft, and ensure power is on when resetting.
