Lennox IMC Integrated Modular Control Secondary Gas Valve Circuit Board — 56K85
SKU: 56K85
$127.00Description
- The Lennox IMC Integrated Modular Control Secondary Gas Valve Circuit Board is an authentic factory-authorized OEM replacement module engineered specifically to regulate the secondary gas valve assembly inside complex multi-stage or multi-burner heating systems.
- Precision-fabricated under strict parameters by Lennox Industries, this premium G1-2 IMC sub-module manages specific combustion timing intervals and high-fire burner sequences, working in complete harmony with the primary ignition master board to optimize structural air-fuel ratios during peak demand cycles.
- The heavy-duty board layout is constructed with fortified circuit traces and high-grade solder joints designed to continuously resist the punishing vibrations, high humidity, and aggressive ambient heat levels typical of commercial rooftop air handlers and large-capacity furnaces.
- Ideal for licensed commercial HVAC mechanics, plant engineers, and property facility supervisors, the 56K85 drop-in module connects seamlessly into existing factory wiring harnesses to restore precise multi-stage safety logic and permanently eliminate intermittent heat dropouts or communication link fault codes.
