Description
The Rheem-Ruud AP14320F Thermocouple is a flame-sensing safety component used in a heating system. Designed with a 24-inch probe length, it generates a millivolt signal when exposed to pilot flame heat to maintain gas valve operation during ignition, and burner cycles in HVAC systems. It is commonly installed in water heaters and furnace assemblies where continuous flame detection is required for safe gas flow control, and stable heating performance. Within the burner system the thermocouple operates as a safety monitoring part that supports flame verification, ignition and coordinated combustion operation during heating cycles.
