Nordyne 622338 Transformer 340793-762 The Open Air Over (OAO)

The Open Air Over (OAO) design ensures the internal windings remain cool through continuous operation by utilizing the system's own airflow

You must match the capacitor MFD rating to your specific supply voltage (5 MFD for 208V or 3 MFD for 240V) to prevent winding damage

reducing installation time and preventing premature failure

allowing for accurate modulation of pneumatic actuators or dampers within a control circuit

the 100110123 is the official updated OEM replacement for part number 9004855105 and 60003-12

Nordyne 622338 Transformer 340793-762 The Open Air Over (OAO)The Nordyne 622338 Transformer is a heavy duty step down transformer engineered to convert 240V AC primary input to a stable 24V AC secondary output. Rated at 30VA, this OEM component is a staple for residential and commercial HVAC service, providing the necessary low voltage power for integrated furnace control boards, 24V thermostats, and ignition systems. As a veteran technician knows, a 30VA power rating is the sweet spot for many furnace repair
