About This Item
The Pentair High Pressure Switch (473655) is the OEM replacement pressure switch for the ThermalFlo HP Titanium heat pump series.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Heat pump components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service refrigerant circuit or high-voltage components without proper certification.
The high pressure switch monitors refrigerant circuit pressure within the ThermalFlo HP Titanium heat pump. When system pressure exceeds the safe operating threshold, the switch interrupts the compressor circuit to protect the unit from damage. A failed or faulty high pressure switch can cause nuisance shutdowns, prevent the heat pump from reaching set temperature, or leave the compressor unprotected during an over-pressure event. Replacing this switch with the correct OEM part restores accurate pressure monitoring and proper safety cutout function.

Pro Tip
Before ordering, locate the part number on the original switch body and confirm it matches 473655. High pressure switches can vary by refrigerant type and pressure rating — installing a switch with an incorrect cutout pressure can leave your compressor unprotected or cause the unit to shut down prematurely. If the original part number is no longer legible, cross-reference your ThermalFlo HP Titanium model number against the Fits Into table above to confirm fitment. Service of this component should be performed by a licensed pool professional or qualified HVAC technician.
