Tech found X13 blower receiving high and low voltage but not running. Thins indicates a failed blower. Motor/Module need to be replaced. Customer also complained of 1 room being warmer than the others. Tech found that unit is ran off a different thermostat, and the thermostat for that room is located in a restricted area. Tech recommends lowering that thermostat once the area is no longer restricted to see if room is now getting airflow.
