Replacement Gas Valve

This replacement control board is engineered for Lennox, Armstrong, and Ducane single-stage gas furnace systems requiring reliable integrated ignition module functionality. Operating at 24V with input voltage range of 18-30 VAC at 50/60 Hz, this board delivers consistent performance across standard HVAC installations. The unit features a silicon nitride hot surface ignitor output rated at 2.0 A @ 80 VAC, ensuring efficient and dependable ignition for residential and light commercial furnace applications. The integrated inducer relay supports 2.2 FLA / 3.5 LRA @ 120 VAC, while the blower relay accommodates up to 14.5 FLA / 25.0 LRA @ 120 VAC for heat, cool, and fan mode operation. A dedicated gas valve relay provides 1.5 A @ 25 VAC at 50/60 Hz for precise fuel delivery control. This control board is rated for operating temperatures ranging from -40 Degrees F to 176 Degrees F (-40 Degrees C to 80 Degrees C) and maintains functionality in humidity environments of 5-95% RH non-condensing, making it suitable for diverse installation locations. The plug-in design enables straightforward replacement without extensive rewiring, reducing installation time and labor costs. This component is essential for maintaining proper furnace operation and is recommended for HVAC technicians and facilities managers performing routine maintenance or emergency repairs on compatible Lennox furnace systems.
