I have a modine hot dawg 45 in my garage it's barely a year old and it is very noisey. It started out somewhat quiet but has steadily gotten louder to the point that I need to do something because it is drowning out my tv in my house! I can't seem to find exactly where the noise is coming from but it seems its definitely from the fan vibrating the unit and the sound is coming through the wall in my house. Any help would be greatly appreciated!
