I performed a comprehensive diagnostic on a 2-year-old Rheem package heat pump. Upon inspection, I identified an issue with the voltage distribution system. The faulty voltage distribution was causing inconsistent performance and potential damage to the unit. I meticulously checked the electrical connections, wiring, and control board for any signs of wear or damage. After isolating the faulty components, I replaced the defective parts and recalibrated the system to ensure optimal performance. The heat pump is now operating efficiently, and the issue has been fully resolved.
