On arrival found the condensate pump unplugged. Plugged the pump back in and the pump turned on and pumped out the water. When the GFI trips the pump losses power and then the system will not work in heating or cooling. At this point I would recommend running a new drain line and remove the condensate pump as it isn't really needed. Searched for a 410a leak and wasn't able to locate one. Will try again when we return to complete some other work. Note: Zone damper 4 will only close to 1 instead of 0. Which allows some air flow through the damper.
