This HVAC Compressor Training is a comprehensive guide covering Capacitor Wiring, Hard Start Kits & Voltage Drop troubleshooting! This essential training breaks down the most complicated repair in refrigerant systems - the compressor.
What You'll Learn:
Proper capacitor and contactor wiring configurations
Understanding compressor terminals: Common, Start, and Run
How capacitors actually work (electron flow and storage)
The difference between compressor common and capacitor common
Hard start kit installation and when to use them
Potential relay operation and back EMF
Voltage drop diagnosis during startup
Why compressors fail and how to prevent it
Key Topics Covered:
Run winding vs. start winding configuration
Dual capacitor wiring (hermetic and fan)
How capacitor size affects motor performance
Copper plating and acid contamination issues
Inrush current and voltage considerations
208V vs 230V applications
CPT terminal (sacrificial protection)
Perfect for HVAC technicians who want to understand the "why" behind compressor repairs, not just the "how." Stop relying on incorrect mental models and learn how these systems actually function!
