Westinghouse 632401 High Pressure Switch Ac

Product Description

The WESTINGHOUSE 632401 is a high pressure switch designed for residential split system air conditioners. This safety device monitors refrigerant pressure on the high side of the refrigeration circuit and cuts power to the compressor when pressure exceeds a safe operating threshold. It protects the compressor and system components from damage caused by abnormal high-side pressure conditions. Licensed HVAC technicians install and service this switch as part of routine maintenance, diagnostics, or component replacement on residential cooling systems.

This switch is used on the PSA4BC residential split system air conditioner. It is installed on the high-pressure side of the refrigerant circuit, typically near the compressor or discharge line. This type of switch is a standard safety control found in residential split system installations and is replaced when the switch fails to reset, trips repeatedly, or tests out of specification during service diagnostics.

Key Features

• Monitors high-side refrigerant pressure to protect the compressor from over-pressure conditions
• Designed as an OEM-style replacement for the PSA4BC residential split system platform
• Serves as a safety cutout to interrupt compressor operation under fault conditions
• Direct replacement reduces diagnostic and installation time in the field

Compatibility

Designed for use on the WESTINGHOUSE PSA4BC residential split system air conditioner.

Installation Notes

Installation should be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for refrigerant handling. Before servicing, disconnect electrical power to the unit at the disconnect box and recover refrigerant from the system per EPA regulations before removing the switch. Use proper refrigerant service equipment and follow all applicable local mechanical codes when reinstalling and recharging the system.
