We arrived at the home to find the system off. We immediately got to work and replaced the zone control board and the blower motor. I made new connections with the zone control board transformer using WAGO lever nuts. I made sure to install a standalone transformer for the zone control board. Chey replaced the upstairs thermostat and programmed it. I programmed the zone control board. We went outside and replaced the capacitor and then tested the system. The system came on and ran properly. System is in working order at completion of appointment.
