Intertherm making weird noise
Posted: Tue Dec 27, 2011 8:17 pm
I have a INTERTHERM furnace, the model number on the internals is E2EB-020HB. The furnace seems to work fine during the day but early in the day usually 2-3 a.m. it will start running then make a annoying humming noise followed by a knocking sound. It almost sounds like something is hitting the sides of the unit but when I open the door of the unit up I see nothing. Any thoughts on how to stop this would be greatly appreciated.
