Customers can find information about how to troubleshoot a Chamberlain garage door by visiting the Chamberlain Frequently Asked Questions page at Chamberlain.custhelp.com. Answers are provided for common problems such as programming a keyless entry PIN, programming the remote control device, adjusting travel and force limits, and testing safety reversing sensors.
To program or change a keyless entry personal identification number for a Chamberlain garage door opener, find the Learn button located near the antenna. The Learn button has a small LED light right next to it and is identified by its green, red, orange, yellow or purple color. Garage door openers with a MyQ panel have a bar that must be lifted first in order to view the learn button. Activate the button by pressing down and releasing it once or twice. Enter the PIN number within the 30-second allotted time and press the enter key, which triggers the indicator light to start blinking.
Programming a Chamberlain garage door remote control involves similar steps to programming a four-digit PIN number. Adjusting the travel and force limits involves four steps and requires a properly installed safety reversal system that must be tested again after the adjustments are made. Obstruction or misalignment of safety reversal sensors often leads to flashing lights and also prevent the door from closing all the way.
