Precision Safety: Maintains the integrity of the flame rectification circuit

With a 26 Ohm coil resistance and a temperature operating range from -20°F to 150°F

this 1 pole 40 amp 24V contactor offers a critical advantage: its silver cadmium oxide contacts are designed to minimize pitting and welding under heavy inductive loads

It is intended for use with standard threaded stem designs

preventing intermittent ignition failures or pressure switch trip codes that often plague older Nortek furnace parts

White-Rodgers S84-11 Transformer Precision Safety: Maintains the integrityThe White Rodgers S84 11 Transformer is a heavy duty 120V to 24V step down transformer engineered for reliable performance in demanding residential and light commercial HVAC applications. As a Class 2 energy limiting transformer, this 40VA rated model provides a stable secondary output of 24VAC, making it the industry standard for powering gas valves, 24V thermostats, fan controls, and relay centers.
