46-101496-01 Rheem 24V transformer 120V 40VA

The Rheem 46‑101496‑01 is an OEM 40VA control transformer used across Rheem and Ruud furnaces, air handlers, and packaged HVAC systems. It steps 120VAC primary power down to a stable 24VAC secondary, supplying low‑voltage control power for thermostats, circuit boards, gas valves, relays, and safety circuits.

Built to Rheem specifications, this transformer provides reliable output, consistent performance, and long service life. Ideal for replacing failed or weak transformers causing blown fuses, intermittent control voltage, or system shutdowns.

Grounded from product data:

• PlumbersStock lists it as a 120V → 24V, 40VA Rheem transformer
