Match the model before choosing a document

Identifier: 4280V. Keep every letter and suffix on your product label when checking applicability.

The 4280V section identifies GUAT-343 as the motor assembly and GUAT-370 as the opener cover. Keep both complete numbers when comparing a service part with its label or paperwork.

Its listed controls include the D3B remote and 3-FDCC deluxe door-control console. The same section lists GUAT-369 for the logic board, GUAT-309 for its holder and GUDT-361A for the motion sensor.

The official DOCX supplies component identification for 4280V. It does not establish that another model with a similar number accepts the same assembly, or supply a checked repair procedure.
