Friedrich 67401300 High Pressure Switch

Product Description

The FRIEDRICH 67401300 is a high pressure switch designed to protect refrigeration and air conditioning systems from dangerous over-pressure conditions. It monitors system refrigerant pressure and interrupts the circuit when pressure exceeds a safe operating threshold, preventing compressor and system damage. This switch is a direct OEM replacement part installed by licensed HVAC technicians during routine maintenance, system repair, or compressor changeout procedures. Its straightforward form factor allows for efficient field replacement in applicable Friedrich cooling equipment.

This high pressure switch is intended for use in Friedrich refrigeration or air conditioning units where refrigerant circuit protection is required. It is rated for installation in systems that call for OEM-specified pressure control components. The switch functions as a safety cutout in the high-side refrigerant circuit, making it a critical component in ensuring system longevity and safe operation across residential and light commercial applications.
