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.
