Ao Smith 100283641 Hsi Igniter Gen 2 Intelli-vent Hot Surface Igniter Replacement

Product Description

The AO Smith 100283641 is a Gen 2 Intelli-Vent hot surface igniter (HSI) designed as a direct replacement for gas-fired water heaters that use the Intelli-Vent control system. This igniter is a critical component in the ignition sequence of residential and light commercial water heaters. When the thermostat calls for heat, the control board sends voltage to the hot surface igniter. The igniter heats up rapidly to a temperature high enough to ignite the gas burner, eliminating the need for a standing pilot light. This design improves safety and reduces gas consumption compared to older pilot-based systems. The Gen 2 version of this igniter incorporates an updated ceramic heating element that reaches ignition temperature faster than first-generation designs. The ceramic construction provides long service life and consistent performance across thousands of ignition cycles. HVAC technicians and plumbing professionals rely on this part when troubleshooting no-heat or no-ignition faults on AO Smith water heaters equipped with the Intelli-Vent control system. Common failure symptoms that point to a faulty HSI include the burner not lighting, the control board flashing fault codes related to ignition failure, or visible cracks in the igniter element. Installing the correct OEM-matched igniter ensures compatibility with the existing Intelli-Vent control board and avoids misfire or lockout conditions. This part weighs 0.2 pounds, making it easy to carry as a standard stock item for service technicians. It is used in both residential water heater applications and light commercial settings where consistent hot water supply is essential.
