Outdoor Heat Pump Electrical & Refrigerant Components Walkthrough! What They All Do!

In this HVAC Training Video, I Explain all the Parts on this American Standard Trane Outdoor Heat Pump! This unit did not have an Accumulator or a Charge Compensator. It just had a standard Muffler on the Discharge Line! I go over the Dual Run Capacitor, Start Capacitor, 5,2,1 Potential Relay, Contactor, Reversing Valve, True Suction Port, Vapor Service Valve, Liquid Service Valve, Muffler, Compressor, Thermal limit Switch, Low Pressure Switch, Thermostat Wiring, Filter Drier, Coil Temp Sensor, Ambient Temp Sensor, Defrost Control Board, and the Fan Motor!
