How do i fix a noisy range hood? - Baumatic Kitchen Ranges

Take the nut to a hardware store and ask for a self-locking nut. That type nut shouldn't spin off again. That MIGHT solve the noise problem, if the fan blades are wobbling, or the shaft is spinning within the fan's center.

Kit-aid sells blowers that are near silent, call 1-800-422-1230. Have your model number ready and they will get you what you need

Hey..... It works.... thats what counts

HI. The most common issue here will be with a loose motor shaft. This is the part that the fan blades are mounted on. When this occurs, the looseness will cause the motor, and shaft to wobble, thus, causing this noise you here at high speeds. The wobble is less violent during the slower speeds, so it is not loud, in this case.

The second issue will be a warped fan blade. This will cause the fan to rub against the shroud, thus, creating the noise, as well.

If the shaft is loose, or bent, the entire motor will need to be replaced. Now, if the fan blade is warped, you can, simply, unscrew the blade from the shaft, and replace it(on most model)

You might try your local furnace or heating shop as they can usually custom make ducting and may be able to do this for you, but I am sure it will cost. I have had similar problems and usually a good sheet metal man can help.

Sounds like fan has become faulty - suggest contact manufacturer directly

We have the same product, 18 months in use and the very noisy motor has finally seized up. I contacted the manufacturer and was advised that I need a new motor, motor mounting bracket and fan rotor. The agent was not able to quote me a price for the parts but stated that even though my 1-year warranty had expired, if I faxed them a copy of the original sales reciept they could possibly send me the parts for free under the original warranty agreement. I've done as they asked but haven't received a reply as yet. After reading about all the problems with this product I'm tempted to dump the whole unit and try to find another manufacturer that has a reliable and QUIET range hood.

Replace Fan Motor
Product Label Says Not To Lubricate Bearings Because they
are permanently Lubricated. However, the bearing are actually gimbal mounted and held in place by a Flimsy Retaining Plate.
Lubrication will only evaporate under oven use due to the rising Heat.
