Found system operating normally, discovered other upstairs loft area also service by this unit had thermostat in auto position which may have been calling for heat at the same time that the art studio was calling for cooling causing zone control to get confused and not apply both settings at once it decided to do nothing. Recommend keeping both thermostats in the same mode setting.

When I arrived complaint was system was not coming on when art room zone was calling. Set thermostat to cool and 68. System came on and worked properly. Blower was pulling 2.4 amps Compressor was pulling 6.2 amps, and out outdoor fan was pulling 1.2 amps. My temperature difference between return and supply was 23. I did find that with the cooler temperatures outside the system was short cycling due to discharge air temperature reaching 40 degrees. This is caused by lack of heat load, and the art room being such a small zone. System would run for 7 minutes, the turn off for 2. The temperature in the art room did drop from 76 to 70 by the time I finished testing everything. If system does not come on again or struggles to reach temperature call us back out.

Found condenser fan motor has seized and will not spin attempted to force the motor to spin to no avail recommend replacement of condenser fan motor. Replaced condenser fan motor and cycled system to check operation. Everything runs normally again!
