The Heil Quaker ICP 1070066 Pressure Switch is a critical safety and performance component designed for specific ICP, Heil, and Quaker heating and cooling systems. This Low Pressure Switch operates with a precise Cut-Out (CO) of 100 PSI and a Cut-In (CI) of 250 PSI. Built for high-reliability refrigeration and HVAC applications, this SPST pressure control monitors the system?s refrigerant levels to prevent compressor damage due to low-pressure conditions. As an OEM replacement part, it ensures direct compatibility and maintains the factory-specified safety parameters of the original equipment. Contractors should verify the actuation points against the system?s service manual to ensure proper cycling. The robust construction is engineereed to withstand the vibration and thermal cycling common in condensing units and heat pumps. This HVAC pressure sensor provides accurate electrical switching to the control board, preventing the system from running "dry" and ensuring long-term operational integrity in demanding field environments.

Key Benefits

• Precise Setpoints: Pre-calibrated 100 PSI CO and 250 PSI CI for accurate system monitoring.
• OEM Compatibility: Direct fit for numerous ICP and Heil Quaker models, reducing installation time.
• Compressor Protection: Prevents catastrophic failure by interrupting the control circuit during low-refrigerant events.
• Durable Construction: High-grade materials designed for long-term exposure to standard HVAC refrigerants and oils.
• Standard Wiring: Features standard spade terminals for seamless integration into existing HVAC wiring harnesses.

Common Questions

Is the ICP 1070066 compatible with R-410A systems?
Yes, this switch is designed for high-pressure environments typically found in modern R-410A HVAC systems, provided the system's cut-out requirements match the 100/250 PSI specifications.

How do I troubleshoot a suspected faulty pressure switch?
Technicians should use a multimeter to check for continuity across the terminals when the system is under appropriate pressure. If the circuit remains open while the system is above 250 PSI, the low pressure switch likely requires replacement.

Can this switch be used as a universal replacement?
While it fits many ICP-manufactured brands, always match the specific PSI ratings and thread type (typically 1/4 inch SAE flare) before attempting installation on non-Heil Quaker units.
