Htpg 204464021 Low Pressure Fan Cycling Control 20-100 Psi

Product Description

The HTPG 204464021 is a low pressure fan cycling control designed for use in refrigeration and air conditioning systems where automatic pressure-based fan switching is required. This OEM-style control features a 1/4 inch male flare connection and includes a capillary tube for sensing system pressure. It operates across a range of 20 to 100 psi with SPST switching action and an auto-reset function, eliminating the need for manual intervention after a pressure event. Licensed HVAC technicians and refrigeration service pros install this control as a direct OEM replacement. It is also cross-referenced as O10-1401 and P70AB1.

This control is used in residential and light commercial refrigeration and air conditioning equipment where low-side pressure monitoring drives condenser fan cycling. It is typically installed on the suction or low-pressure side of the refrigerant circuit. The hose-style body and 1/4 inch male flare connection suit a range of field installations. The auto-reset design makes it well suited for cycling applications where manual reset after every pressure drop would be impractical.

Key Features

• Pressure range: 20 to 100 psi for low-side fan cycling control
• SPST switching for straightforward fan circuit integration
• Auto-reset operation eliminates manual reset after pressure events
• 1/4 inch male flare connection with capillary tube included
• Hose-style body for flexible field installation
• Cross-references to O10-1401 and P70AB1 for broad replacement applicability

Compatibility

OEM replacement control that cross-references to part numbers O10-1401 and P70AB1. Suitable for refrigeration and air conditioning systems requiring low pressure fan cycling control with a 1/4 inch male flare connection in the 20 to 100 psi operating range.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Recover and isolate system refrigerant per EPA Section 608 requirements before disconnecting or replacing any pressure control component. Verify the replacement control pressure range matches the system low-side operating parameters before commissioning. Do not overtighten flare fittings; use appropriate flare wrenches and follow standard industry torque practices.
