Question about Broan-NuTone N-QT9093WH Combination Heater Heater Kitchen Hood

Should I buy a new exhaust fan or try to fix old one?

The fan motor is very loud in this unit. We bought the house six months ago and it seems to be getting worse. We have the same one in the kids' bathroom so I know it isn't supposed to sound this bad. Can I replace just the fan/vent motor or should I just buy a new one? I found one for under $250 in white, ours has the brass ring, but I don't really care about that. I'm thinking if I do replace it I should buy the same one though so I don't need to cut a new whole or do repairs. Any thoughts? I did take off the exterior and look for vibrations, but it seems to be in there sturdy.

If the air flow in the duct is restricted, that can cause excess noise also.

I have a" Nautilus Microtek

The motor is getting worn to the point it will stop soon. Remove the screen and you find the fan/motor directly behind it. You can try to put some machine oil on the motor shaft next to the motor housing. It may quieten it some. Recommend you replace it. Be sure you disconnect power before you do anything else. The motors and fan assembly is small in size and can be bought in Home Depot or an appliance store. If you need assistance in removing the motor/fan and installing new one, please let me know. Those brands are found at Home Depot.

So noisy even on low

Does the fan seem like it is spinning off balance. What exactly is making the noise, the fan or the motor. I will see if I can find an owner's manual. Please get back to me on my questions

I have a 4 year old RM5200 hood over my stove. The motor is making a whining noise. It seems to soon for this to happen. It is loud and constant to the point where we don't want to use it. Is it time...

Range hood motors, bathroom exhaust fan motors all share the same thing. They become coated with grime inside the shaft of the rmotor due to their exhaust feature of sucking dust and grime over the motor, which is open. The only solution is to get access to the motor and clean the fan blades and squirt a little WD-40 down the shaft as that is where the noise comes from. The dirt and grime build up on the motor shaft, and eventually starts rubbing the bushing where the shaft rest and makes a noise. Yo must remove this from the shaft and allow a little play, and lubrication which the WD-40 will supply.

The exhaust hood of my restaurant is very noisy. The problem started 2 months ago.

I would first clean the hood throuoghly, and then check the bearing on the fan, also check if the fan blades are bent.

Range hood is making noies

use a good 3 in 1 oil. Don't use WD-40 it will only clean it then dry out the bearing. the problem will be worse than when you started.

Install a Thermador UCV36 cook'n'vent

Hi schmidt_rich,

I'm Harvey the Master Plumber.

Your question is: You took over as owner builder when your builder "took the $ and ran". You are installing kitchen cabs now and discovered the PVC vent pipe (which goes into the foundation and out the side of the house) is in the wrong place for the location of the downdraft unit and integral blower. The vent is actually under the electrical connection panel. You were told initially( 2 yrs ago when you bought the downdraft cook'n'vent) there could be no bends in the exhaust fan route or it would change the effectiveness. Does anyone know if it is ok to put a bend in the connection to the vent? Or do you need to redo your kitchen cabinets?

I can syphathise. I have had to deal with this same problem. I have found that one ell will not degrade the effectiveness enough to notice. If you need more then you may need to adjust cabinets.

Feel free contact me again!
