Common failures & inspection points
Oil pressure verification - ensure operating compressors meet OEM specifications and oil pressure differential is within manufacturer range
Crankcase/oil reservoir level check - confirm oil is within operating range and free from contamination or degradation
Discharge temperature monitoring - log compressor discharge temperature against design range; high temperatures indicate low refrigerant or oil issues
Refrigerant charge and pressure - verify suction and discharge pressures match design conditions; abnormal ratios indicate refrigerant shortage or condenser fouling
Oil analysis sampling - extract oil samples for laboratory analysis of viscosity, acid number, moisture, and metallic wear particles to detect bearing/seal degradation
Safety control testing - manually test high-pressure cutout, low-pressure cutout, high-temperature cutout, and oil pressure differential controls against setpoints
Vibration and noise assessment - inspect for unusual vibrations or acoustic signatures that may indicate compressor wear, internal damage, or bearing issues
Motor amperage and electrical integrity - verify motor current draw, phase balance, and control system voltage stability during operation
