1 system CCM- Checked heating operations of 2020 Rheem heat pump and air handler. Replaced 20x20x1 filter, Checked capacitor outputs and amp drawls, Checked refrigerant levels and auxiliary heat, Triggered safety switches and defrost mode, Checked delta T, and cleared drain line. Heat pump breaker was also tripped, I reset system and preformed an inspection to find a shorted compressor. Will be calling supplier for part availability. Pics uploaded, P&L
