York 025-27911-000 Transformer

When you're out in the field, reliable components are the backbone of a solid repair. The York 025-27911-000 Transformer is a critical electrical part designed for consistent performance in many York chiller and HVAC applications. This 115V AC primary unit steps power down to a specific 19.8V AC secondary output, providing the precise low-voltage signal required for sensitive HVAC control boards and thermostat circuits. Built with a rugged rolled steel frame and a corrosion-resistant aluminum flange, it is engineered to handle the thermal fluctuations of high-demand environments. Whether you are performing an HVAC replacement or troubleshooting power issues, this step-down transformer ensures stable voltage across your single-phase systems without the excessive hum or vibration common in lower-grade alternatives. The compact 3.65-inch footprint allows for easy mounting in tight control cabinets, making it a dependable choice for maintaining HVAC system efficiency.

• Precise Output: Delivers a 19.8V secondary voltage, specifically balanced for York-branded control circuits.
• Robust Construction: The rolled steel frame provides superior durability and heat dissipation.
• Compact Integration: Small form factor (3.65" x 4.45" x 3.65") ensures adaptability in crowded electrical compartments.
• Corrosion Resistance: Aluminum flange design prevents oxidation in high-humidity mechanical rooms.
• Direct OEM Fit: Eliminates the guesswork associated with generic voltage adapters.

• What causes an HVAC transformer to fail? Most failures result from a short in the secondary circuit, a faulty contactor pulling too many amps, or power surges on the primary side.
• Can I use a 24V transformer to replace this 19.8V model? We recommend following the exact manufacturing specs. This 19.8V output is calibrated for specific board tolerances; substituting a higher voltage may lead to control board overheating or failure.
• How do I verify if this transformer is bad? Using a multimeter, check the 115V primary input at the terminals. If primary power is present but there is no 19.8V output on the secondary side, the internal windings are likely open.
