The GC Valves S311GF02N9CF5 is a high-performance

This single pole single throw control is typically wired in series with the compressor contactor coil

protecting internal electronics and the heat exchanger

As a direct replacement for legacy York 24V relays

the 100093984 maintains consistent pilot flame stability to prevent nuisance lockouts and voltage drops in commercial heating circuits

Lennox 46K08 Limit switch 320788-704 The GC Valves S311GF02N9CF5 isThe Lennox 46K08 Limit Switch is a critical safety component designed for precise thermal regulation within residential gas furnaces and air handlers. Engineered for high reliability applications, this auto reset limit switch operates within a predefined 140 160F temperature range, ensuring the heat exchanger does not exceed safe operating limits. When the plenum temperature reaches the high end threshold, the switch opens the electrical circuit to
