Common Air Compressor Problems & How to Fix Them

From oil leaks to overheating, we cover the most common compressor issues. If your compressor won't start, check the obvious first: power supply, pressure switch settings, and oil levels. Overheating is another common issue, usually caused by poor ventilation around the unit, a dirty oil cooler, or restricted air intake. If the compressor is running but not building pressure, you might have a blown gasket, a faulty intake valve, or worn piston rings. Always disconnect power and bleed air pressure before attempting any repairs.
