Description
The Nordyne 632185 36″ Thermocouple H is a temperature-sensing component used in gas-fired systems, including furnaces and boilers. It is installed near the pilot light to detect flame presence and generate a small electrical signal that keeps the gas valve open during normal operation in HVAC systems. It is used during system maintenance as a direct ignition control within the heating system. It operates as part of the ignition safety circuit, working control valve and burner assembly to ensure accurate and regulated furnace operation.
