Look on the motor unit near the hanging antenna or wire terminals; the remote in your hand may not show the opener's system.
What this clue means
Chamberlain Group says the button is on the back or right side of the opener, close to the antenna wire. Read the motor housing label while you are there. Do not press and hold the button while searching; on some units that can erase programmed devices.
Confirm it on your opener
Find the model sticker and compare the button with the manufacturer identification chart. Fading, replacement circuit boards and similar case designs can mislead you. If you cannot confirm the family, the correct status is unknown.
Next step
Run the finder with the brand, button color and shape. Then use the official compatibility tool or manual to check your particular opener before buying.
Read the label while you are there
The back or side of the opener near the hanging antenna is where Chamberlain Group points owners for the LEARN button. A stable ladder and good light matter, but do not touch moving parts or remove electrical covers to search. Once you can see the button, note its shape and color plus the exact motor-unit label. Those details are more useful together than any one clue on its own.
