Where is the reset button on Chamberlain garage door?

To reset programming and erase all remote controls, keypads, and MyQ devices on Chamberlain opener, locate Learn button on motor unit mounted on ceiling, usually yellow, purple, or red square button near antenna wire, press and hold Learn button for 6 to 10 seconds until LED turns off, indicating all codes erased, then reprogram remotes. To reset travel limits and force settings, use adjustment buttons on motor unit or MyQ app to reset limits to factory defaults. To reset logic board after power surge or error, unplug opener from power outlet for 30 seconds to 1 minute, then plug back in, power cycling resets board.
