for Gahanna, OH
customer stated loud noise coming from attic, house is a four level split and furnace is in the basement, the furnace is a 90% and vents out the side of the house. The duct work does not go into attic, system cools top floor from its floor vents. I did still go into attic to look and found there is a section not sealed off to the outside and tech informed the customer of that as well as went over furnace & ac while here
Performing a diagnostic check on a Gibson/Nordyne Gas Furnace. Found 120v coming into furnace but furnace not coming on. The door switch failed and caused a partial burn on the wire. Bypassed door switch and system now operational and heating at this time.
