Trane SWT1273 Limit Switch Els PW 17895 the Nordyne 259200R is theThe Trane SWT1273 is a critical safety component designed for furnace heat exchanger protection and blower control. As a technical auto limit switch, this high limit temperature switch features an L220 30 rating, which means it is engineered to open the circuit and interrupt heating operation when internal temperatures reach 220F. Once the system cools down to 190F, the switch automatically resets to resume normal unit cycles without requiring a
