Customer stated their blower fan is consistently running. She has had the furnace off all summer and just fired it up and it will just blow consistently. Upon investigation, the technician found that the damper control was sending 24V to G terminal while switched off. This indicates a stuck closed relay. I disconnected it and tested the unit. Due to age of unit, I would recommend upgrading to a more efficient model.
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
