Tech arrived to problem call for entire home. System is a zoned system located in upstairs closet servicing entire home. Both thermostats have power and are actively telling the system to come on. Inspected indoor unit. Unit was not running at all. Found zone board LEDs not lit up as intended. Verified zone board has incoming power and outgoing R on thermostats. Zone board is not able to recognize incoming calls from thermostat therefore not running. Found that the zone board does not have a dedicated transformer which more than likely caused failure of the zone board. Jumped out wires to bypass zone board and test system. System did come on inside and out. System only has a float switch in pan and no other safeties. Highly recommended adding wet switch and safety switches along with cleaning indoor cabinet, blower compartment and drain flush. Checked outdoor unit. Unit in full operation, refrigerant pressures within specs. Outdoor capacitor is out of specs at this time. Brought recomm
