Lennox 98M69 Pressure Switch 30067439-890 Field Reliability: Precision-engineered 24V architectureThe Lennox 98M69 High Pressure Switch is a critical safety component designed for high performance HVAC systems, specifically engineered to monitor and regulate refrigerant pressures within the compressor circuit. This 410 210# pressure switch functions as a fail safe, featuring a manual reset mechanism that trips at 410 PSI and allows for system restart once pressures stabilize at 210 PSI. It provides essential protection against catastrophic
