Is there a reset button on a Liftmaster?

There is no dedicated button labeled Reset on a LiftMaster garage door opener, but there are several ways to reset its functions depending on what you need to reset. To reset the logic board or clear error codes, you can unplug the opener from the ceiling outlet for 30 seconds to one minute and plug it back in, which power cycles the unit similar to rebooting a computer. To reset or erase all remote controls and keypads from memory, press and hold the Learn button, which is usually yellow, purple, red, or green square button on the back or side of motor unit near antenna wire, for about 6 to 10 seconds until the LED light goes out, indicating all codes erased. To reset travel limits and force settings, locate the adjustment buttons or use the door control with menu, then follow steps to set up and down limits by running door open and close cycles. To reset MyQ Wi-Fi, press and hold the Settings button or the Learn button until LED blinks. To reset safety sensors, disconnect wires and reconnect. LiftMaster openers have a Learn button that acts as programming reset, not a factory reset button. If opener is not working after reset, check power, photo-eyes alignment, and ensure manual lock not engaged. Professional reset help costs 75 to 150 dollars service call.
