Warranty new construction Inspected operations of furnace and furnace blower motor. Ran each zone separately and at this time the system is operating normally. Photos of model numbers and serial numbers are uploaded just in case the ECM blower motor has an intermittent issue and the code that was present this morning for filter change reoccurs. If motor cannot run code reappears after installation of new filters and adjustments at thermostat made today Reoccurs in a short period of time at that point replacement of furnace blower motor would be recommended.
