Replacement Gas Valve

This replacement control board is engineered for Lennox SureLight series single-stage gas furnaces, providing reliable management of ignition sequences and blower operations in residential and light commercial heating systems. The board operates on 24 VAC input at 50/60 Hz, making it compatible with standard HVAC control voltage systems. The control board delivers precise electrical outputs for critical furnace functions. The hot surface ignitor output provides 2.0 A at 80 VAC for consistent ignition performance. The inducer relay is rated at 2.2 FLA / 3.5 LRA at 120 VAC to control draft induction, while the blower relay supports up to 14.5 FLA / 25.0 LRA at 120 VAC for variable-capacity circulating blower operation. The gas valve relay operates at 1.5 A at 25 VAC, 50/60 Hz for proper fuel delivery control. Designed for demanding HVAC environments, this control board maintains reliable operation across an extended temperature range of -40 Degrees F to 175 Degrees F and operates efficiently in humidity conditions from 5 to 95 percent relative humidity (non-condensing). This specification ensures long-term performance in both conditioned mechanical rooms and unconditioned spaces. The board integrates all essential furnace controls into a single component, eliminating the need for multiple relay modules and reducing installation complexity. Technicians benefit from a straightforward replacement that restores complete furnace functionality without requiring system reconfiguration. This component is ideal for HVAC contractors performing maintenance, repairs, or emergency furnace restoration in residential and commercial applications.
