I conducted a comprehensive diagnostic on a Rheem heat pump to identify and resolve any issues affecting its performance. The process began with a thorough visual inspection of the unit, followed by a detailed examination of the electrical components and connections. I tested the thermostat settings, checked refrigerant levels, and assessed the compressor and fan motor functionality. Additionally, I evaluated the heat exchanger and air flow pathways to ensure optimal operation. After identifying a faulty capacitor, I replaced it and recalibrated the system. The heat pump now operates efficiently, providing reliable heating and cooling as intended.
