Universal means a published list of supported code systems, not every garage door opener.

The detail that controls fit
The ACSCTG-UNIV2 chart names 16 distinct technology entries. It does not list current white Security+ 3.0, and its programming guidance excludes pre-1993 openers and requires working photo eyes.
A practical next step
Write down the full opener or accessory model number from its label. Use the linked manufacturer documentation to match the exact replacement part. If a safety part or wiring is involved, bring that information to a trained technician.
Evidence status
Only the facts identified above are supported by the current source set. Missing model-to-part pairs remain unknown.
A chart is a checklist, not a blanket promise
Genie’s ACSCTG-UNIV2 chart has distinct rows for Intellicode, CodeDodger, several Chamberlain Group LEARN-button generations and other named systems. Look for the row that matches the installed receiver, then read the safety and age notes around it. White Security+ 3.0 is not named in that chart, which means its fit remains unverified here rather than explicitly impossible.
