This Honeywell replacement thermocouple is a critical safety component designed for gas furnaces, boilers, and water heaters. It is engineered for compatibility with systems operating on a 30-millivolt power supply, detecting the presence of a pilot flame to ensure the gas valve remains open only when a flame is present, preventing hazardous gas leaks.
