York S1-3300-3861 Transformer
The York S1-3300-3861 Transformer is a heavy-duty, field-ready component designed for precise voltage regulation in residential and light commercial HVAC systems. This 40VA foot mount transformer provides a stable step-down from a 208/240V primary input to a 24V secondary output, making it an essential replacement for failing control circuit power supplies in York, Coleman, and Luxaire equipment. Its foot-mount configuration ensures a secure, vibration-resistant installation on the control board or chassis. As a genuine Source 1 OEM part, it guarantees electrical compatibility with internal contactors, relays, and ignition modules, preventing the nuisance trips often associated with lower-quality aftermarket equivalents. When troubleshooting systems where the indoor blower or condenser contactor fails to engage despite line voltage presence, this 240v to 24v transformer is the primary solution to restore low-voltage control power and maintain reliable system performance across demanding heating and cooling cycles.
Key Benefits for Technicians- Stable Output: Delivers a consistent 24V secondary signal to protect sensitive electronic control boards.
- Broad Compatibility: Serves as the direct OEM replacement for York, Coleman, and Luxaire furnace and AC units.
- Industrial Build: Rated at 40VA to handle the inrush current requirements of multiple high-draw contactors.
- Standardized Mounting: Features a universal foot-mount design for quick retrofitting in existing cabinet footprints.
Is the S1-3300-3861 compatible with 208V systems?
Yes, this transformer is designed to operate on either 208V or 240V primary circuits typically found in residential heat pumps and commercial air handlers.
What would cause this transformer to fail?
Common failure points include secondary circuit shorts in the outdoor contactor coil, grounded thermostat wiring, or exceeding the 40VA limit by adding high-draw accessories without a power relay.
Does this unit include a built-in circuit breaker?
This specific 40VA model is designed for use within circuits protected by the system's primary fuse or control board automotive-style fuse; it does not feature an integrated reset button.
