York S1-T2404F Transformer

Reliable 24V control power is the backbone of any HVAC service call, and this York S1-T2404F Transformer is the heavy-duty solution for modern furnace and air handler setups. Engineered as a multi-tap control transformer, this unit supports 120V, 208V, and 240V primary inputs, allowing you to carry one part that services a broad range of York, Coleman, and Luxaire equipment. With a robust 40VA power rating, it provides a stable 1.6-amp output at 24VAC, ensuring consistent operation for contactors, ignition modules, and smart thermostats that demand higher steady-state current.

The S1-T2404F HVAC transformer features a versatile foot-mount design for quick integration into existing control cabinets. The color-coded primary leads simplify field voltage step-down wiring—typically using the white wire as common and selecting the black (120V), red (208V), or orange (240V) lead based on line voltage. This OEM replacement part is built for the high-cycle demands of 60Hz secondary circuits, protecting sensitive electronics against voltage fluctuations that often cause nuisance trips in lesser-quality components.

• Multi-Tap Input Versatility: Eliminates the need for multiple SKUs by supporting 120/208/240V primary configurations.
• 40VA Capacity: Delivers sufficient 24V secondary output for contemporary HVAC control boards and solenoid valves.
• OEM Precision: Guaranteed York equipment compatibility ensures lead lengths and mounting footprints match factory specifications exactly.
• Thermal Stability: Heavy-duty windings and solid core construction resist overheating during high-demand cooling or heating cycles.

Can I use this to replace a 30VA transformer?
Yes. It is standard practice to upgrade to a 40VA rating when replacing lower-capacity transformers, as it provides more "headroom" for advanced controls without overloading the circuit.

What happens if I wire the wrong primary tap?
Wiring a 240V line to the 120V tap will immediately blow the internal windings or damages the secondary circuit components. Always use a multimeter to verify incoming line voltage before landing your wires.

How do I handle the unused primary leads?
Unused leads must be individually capped with wire nuts to prevent short circuits against the cabinet or other live components.
