If the pressure switch fails to stay closed despite a clear flue

Zero Differential Operation: The direct lift design allows the valve to function reliably even at 0 PSI

its primary design function is as a safety limit to prevent catastrophic coil damage from freezing

Proper installation ensures the blower housing maintains its designed aerodynamic profile

making it suitable for both standard residential split systems and commercial 208V single-phase applications

Carrier HC40GQ236 Motor 326058-755 If the pressure switch failsThe Carrier HC40GQ236 Motor is a high performance direct replacement for HC40GR236, engineered specifically for demanding condenser fan motor applications in residential and light commercial HVACR systems. Operating at 208 230V on a single phase (1PH) power supply, this 1 4 HP motor provides a steady 825 RPM to maintain optimal heat rejection across the outdoor coil. Built with a PSC (Permanent Split Capacitor) design, it features internal thermal
