Furnace Growl
Does anyone know what this noise could be. When the furnace is on the cool down cycle you hear a load groan like the fan is rubbing something or a real bad bearing but it only does it at the end of the heating cycle. It is quiet when it starts and usually stay's that way for a chunk of the cycle then the noise comes on. So loud it will drown out the TV. The heat otherwise works fine. Any ideas?
