Resideo Q313A1022/B Thermopile 750mV 35" Lead Bulk

The Resideo Q313A1022/B Thermopile is a small but essential component in millivolt gas-fired HVAC equipment, typically furnaces or water heaters. Despite its lightweight design (around 0.12 lbs), it plays a critical role in safe and efficient operation. Made of multiple thermocouples connected in series, it converts heat into a small voltage (750mV) when exposed to the furnace flame. This voltage signal is sent to the gas control valve, which regulates gas flow based on the heating demand. With a length of 35 inches and width of ½ inch, it's designed for easy positioning near the burner flame in most furnaces. The wide frequency compatibility (50/60Hz) ensures it functions with various electrical grids. By sensing heat and generating a corresponding voltage, the Resideo Q313A1022/B thermopile helps maintain proper gas flow and safe burner operation in your HVAC system.
