Where is the learn button on a Chamberlain garage door opener?

On a Chamberlain garage door opener, the Learn button is located directly on the back or side control panel of the motor housing, tucked safely underneath the plastic light lens cover. To access it, open or remove the light lens cover. You will see a square or round colored programming button (most commonly yellow for Security+ 2.0 models, or purple, red/orange, and green for older frequencies) accompanied by a small LED indicator light used for pairing remotes and Wi-Fi networks. Callout type="warning" title="Electrical Safety Warning": Ensure your fingers and tools are kept clear of moving mechanical parts when working near the motor housing. Verification: Press the learn button briefly and verify that the adjacent LED indicator light illuminates to confirm programming mode is active.
