I. Understanding the Three Systems That Determine Whether a Compressor Starts

Every air compressor — whether reciprocating, rotary screw, scroll, or oil‑free — relies on three fundamental systems to start:

1. Power Supply System

   • Incoming voltage

   • Breakers, fuses, wiring, cords

   • Thermal overload protection

   • Motor capacitors (single‑phase units)

2. Control Circuit System

   • Pressure switch

   • Unloader valve

   • Safety interlocks (temperature, oil level, phase protection)

   • Start/stop switch

   • Contactors and relays

3. Mechanical System

   • Pump or airend condition

   • Check valve

   • Shaft rotation and bearing condition

   • Oil level and lubrication

   • Air pressure trapped in the head

If any one of these systems fails, the compressor will not start.
