You must identify the root cause—such as low refrigerant flow

including gas-fired wall heaters and millivolt floor furnaces

the standard 1/4-inch quick-connect terminals and compact oval form factor allow for seamless integration into standard mounting brackets during motor run capacitor replacement

Easy Installation: Includes 6-foot pigtail leads and a strap-on design that eliminates the need for thermal wells or system shutdowns

the contacts are rated for 1/3 HP at 120-240 VAC (N/O) and 1/6 HP (N/C)

Trane CNT1662 High Limit You must identify the rootThe Trane CNT1662 High Limit is a critical safety component designed for precise thermal regulation within furnace and air handler heat exchangers. Built with an L250F SPST NC C High limit configuration, this switch acts as a failsafe by monitoring supply plenum temperatures and interrupting the 24V control circuit if levels exceed the 250F threshold. This immediate shutdown of the gas valve helps prevent structural damage to the primary heat
