Identifying your Chamberlain Garage Door Remote
Finding a compatible transmitter for your garage door remote can be very confusing. In this guide we will show you the steps of how to identify your compatible Chamberlain remote or Chamberlain keypad. The easiest way of finding the remote compatible with your Chamberlain garage door opener is to identify the color of the learn button of your logic board. This is on the back of the motor unit of your garage door. An example learn button is indicated below:

The learn button will be a square button near the center of your logic board. If you have an older model garage door opener, then there will be a set of dip switches that are used to program your opener instead of a learn button. Commercial GDO’s or gate openers might be located differently. Below you will find a reference for the different models of Chamberlain garage door remotes:
