The Genie 35426A.S Transformer is a genuine OEM replacement part engineered for select Genie garage door openers. Installed inside the opener’s powerhead, this transformer converts incoming household AC to the low-voltage power needed by the control board and accessories, helping resolve symptoms such as a dead opener, loss of wall console power, or Safe-T-Beam sensor issues. Using the exact Genie part number ensures proper fit and electrical performance; always confirm compatibility with your opener’s model-specific parts diagram or manual.
Designed for residential garage door opener repair and maintenance, the 35426A.S is intended to be installed in accordance with Genie service documentation. Disconnect power before service, mount the transformer in the designated location within the head unit, and reconnect leads as labeled or per the wiring schematic on your opener. Because this is an internal power component, installation by a qualified technician is recommended. This OEM Genie transformer supports reliable operation of the opener’s logic and accessories and is the correct replacement when your unit specifies part 35426A.S.
