Reznor 102708 Transformer
The Reznor 102708 Transformer is a critical OEM electrical component designed to provide a stable low-voltage power supply for control circuits in industrial and commercial HVAC systems. This 120V to 24V step-down transformer features a 35VA power rating, making it the standard replacement for powering thermostats, gas valves, and ignition control boards in Reznor unit heaters and air handlers. Engineered for single-phase 60Hz operation, this transformer ensures precise voltage regulation, protecting sensitive internal electronics from line fluctuations and preventing intermittent system lockouts. As a genuine system-matched part, it maintains the precise electrical characteristics required for compatibility with OEM control strings, preventing the premature wear common with generic aftermarket alternatives. When troubleshooting no-heat calls where the control board is unresponsive despite having line voltage, this 120V-PRI 24V-SEC 35VA unit is a primary diagnostic point to verify 24VAC output under load.
Key Benefits- Precise 35VA Output: Supplies sufficient volt-ampere capacity to drive redundant gas valves and multiple safety switches without voltage drop.
- OEM Compatibility: Specifically designed for Reznor HVAC equipment, ensuring original terminal configurations and mounting alignment.
- Reliable Control Power: Steps down 120V line voltage to a safe 24V for low-voltage thermostats and control circuits.
- Durable Construction: Built to withstand the high ambient temperatures found in unit heater cabinets near the heat exchanger.
Can I replace a 20VA transformer with this 35VA model?
Yes, as long as the primary and secondary voltages match (120V to 24V), a higher VA rating like this 35VA transformer can safely replace a lower-rated unit, as it provides more available power for the control circuit.
What are the signs of a failing Reznor 102708?
Common indicators include a lack of 24V at the thermostat or control board terminals, a "humming" or "buzzing" sound during call for heat, or a tripped secondary fuse if the transformer has internal resistance issues.
Does this unit come with wire leads?
The Reznor 102708 typically includes color-coded wire leads or spade terminals for direct integration into the existing unit wiring harness, allowing for a quick swap during service calls.
