Shortly after installation the fan began to develop a whinning sound? I checked the tightness of all screws. What else can I do to correct the noise?
Thank you for your question.
Generally speaking, any unusual vibrations or noises will be present from the initial installation and are normally due to a loosely mounted housing, etc. In your case, it sounds as if all was normal for awhile and the “whining” started after a bit. Since this is the case, I would suggest that the ducting be temporarily disconnected at the fan. If the “whining” stops, this usually indicates a problem in the ducting or wall/roof cap. If it continues to be a problem with the duct disconnected, please call the Technical Support group at 800-637-1453 for additional suggestions.
