A/C High Refrigerant Pressure Switch
DESCRIPTIONThe A/C High Refrigerant Pressure Switch is located in the compressor discharge line and monitors the compressor discharge pressure. This switch acts as a safeguard to prevent refrigerant "blow off" from the compressor pressure relief valve and disengages the compressor in the case where refrigerant pressure is above 2965 kPa (430 psi).
