Today I came to Scott’s Balmoral home becuase the furnace stopped working last night. Scott has informed me that early this morning the furnace started working again and has continued to work. We decided to perform a furnace tune up. Furnace tune up: Upon tune up and inspection of the 19 year old system I tested and adjusted the gas valve, burners, gas pressure and temperature rise. Pulled and cleaned the flame sensor. Tested ignition system, inducing motor and assembly, blower motor and assembly, heat exchanger, humidifier, static pressures, tested and tightened all electrical connections, all safety switches and control board. The furnace is in poor condition. The flame sensor, igniter, gas valve, safety switches, control board, and blower motor, are all working well within manufacturers specifications. The gas valve pressure setting were wrong and have been corrected.the inducing motor is vastly over amperage and has advanced bearing ware which is what caused the heating outage y
