Description
The Lennox 85C23 Low Pressure Switch is a genuine OEM replacement component engineered to protect your Lennox HVAC system from the damaging effects of low refrigerant pressure. Designed as a direct-fit replacement, this switch integrates seamlessly into compatible Lennox equipment, ensuring reliable system protection and consistent performance.
How It Works
The low pressure switch continuously monitors refrigerant pressure on the low side of the refrigeration circuit. When pressure drops below the factory-set threshold, the switch opens the control circuit, shutting down the compressor to prevent damage from low refrigerant charge, restrictions, or other fault conditions. Once pressure is restored, normal operation can resume.
