What usually ends its life
Common issues include noise/vibration, overheating, capacity loss, and lubrication-related damage—often compounded by operating outside intended duty cycles or with poor cooling/filtration. Troubleshooting references frequently highlight noise/vibration and performance drop as meaningful signals.
Replace it when you see
-
Capacity loss (can’t reach pressure/temperature targets) that persists after basic checks (filters, airflow, refrigerant/charge or intake restrictions—depending on application)
-
Excessive noise or vibration that is repeatable and not traced to mounting, piping resonance, or line issues
-
Overheating or repeated thermal shutdowns after verifying ventilation, load, and operating conditions
-
Oil/lube-related symptoms (where applicable) that indicate internal damage risk or contamination sensitivity
The replacement line
If you have repeatable overheating + performance loss, or noise that won’t resolve with external corrections, replacement is usually the dependable move—especially when the internal element isn’t practically serviceable in the field.
