First identify whether the white button is the modern round Security+ 3.0 design or an older square DIP design.
Why this matters
The two white entries appear in different generations of Chamberlain Group’s identification chart. A remote that worked with a square white opener cannot be assumed to pair with the current round white family, and the reverse assumption is just as unsafe.
What to do next
Use the motor-unit model and physical button shape to choose the right manufacturer chart. If the button is hard to see, check the manual instead of forcing a pairing attempt.
Do not transfer an old pairing success
A remote that successfully opened a legacy square-white unit has demonstrated only that old receiver relationship. It tells you nothing about a newer opener with a white round button. Likewise, a current white-family remote cannot be assumed to rescue a pre-1993 DIP system. The manufacturer chart separates those generations. If the installed board or button shape is uncertain, identify the actual hardware before buying or trying to enroll a transmitter.
