We have excessive noise and vibration from the blower/fan when it kicks on. We have a G61V. What can be causing this?Post created: 2013-01-25 Type of Equipment: Furnace Views: 67

Model G61MPV furnace fan vibrates and is making unusually loud sound when running.Owned furnace 5 years. Just started doing this last week.We have not tried to fix the problem as yet.Sould it possible be the blower motor?
