York Hot Surface Ignitors

Overview

The SOURCE1 2545231000 is a silicone nitride hot surface ignitor designed as a direct OEM replacement for York and affiliated brand furnaces. Hot surface ignitors are a critical component in modern gas furnace systems. When the thermostat calls for heat, the control board sends voltage to the ignitor. The ignitor heats rapidly to an extremely high temperature, igniting the fuel-air mixture released by the gas valve. This process must happen quickly and reliably every heating cycle. Silicone nitride ignitors are known for their superior durability compared to older silicon carbide designs. They resist thermal shock better, meaning they hold up through repeated heating and cooling cycles over the life of the furnace. HVAC technicians frequently prefer silicone nitride ignitors for replacement jobs because of their longer service life and reliable ignition performance. The SOURCE1 2545231000 is a genuine OEM part, engineered to work seamlessly with the furnace control board, gas valve, and pressure switch systems it was designed for. Using a real OEM ignitor helps protect the equipment warranty and ensures the part meets the original design specifications. This ignitor fits popular York furnace models including the TM9Y080B12MP11, TM9V060B12MP11, and TG9S080B12MP11, among others. HVAC professionals replacing a failed or cracked ignitor on a York gas furnace should verify their model number against the full fits-models list. The ignitor measures 5.95 inches in length, 3.05…
