Completed furnace, maintenance and inspection. I cleaned flame sensor and wiped down furnace. I tested components and amp draws. I found the exhaust on the furnace was leaking water. I popped the joint loose and resealed it. I also found that one of the wires was rubbing up against the inducer motor. I spliced the wire and fixed it. I added zip ties to make sure the wires do not rub on the motor in the future. I talked with customer about club membership. Customer would like to look it over for now. Furnace is operating within manufacture specifications at departure.
