Security+ 3.0 is the current white round LiftMaster family. Its official accessory list should not be carried over to legacy square white units.

What this clue means
The official white-round list includes L991S, L993S, L932M, L993M and L992U. Genie's ACSCTG chart does not name this white generation, so that chart alone cannot establish a fit for the universal remote.
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.
A missing chart row is still unknown
The current LiftMaster white-round list names several models, but the Genie ACSCTG universal chart does not include a white Security+ 3.0 row. That omission does not establish that every third-party remote fails; it means this particular source cannot support an affirmative claim. Use a current accessory-specific chart for any other candidate. For the opener, confirm the round white button and exact model label first.
