Rheem-Ruud 47-102473-03 Limit Switch When diagnosing a pilot lightThe Rheem Ruud 47 102473 03 Limit Switch is a critical safety component designed for high limit thermal protection in residential and commercial furnaces. This SPST normally closed switch is engineered to monitor heat exchanger temperatures and break the electrical circuit if the internal temperature exceeds the 190F open temperature threshold. Once the system cools to the 170F close temperature, the auto reset mechanism restores the circuit, allowing
