I have an Amana Air Command 90 furnace, about 13 years old. ModelGUC/GUX (UPFLOW). There is a very loud buzzing or vibration soundcoming from (I believe) the vent blower motor, possibly from the rightside or lower right side of it as I face it. I'm thinking that Ishould replace the motor, but I'm wondering if it might be somethingelse. Otherwise, furnace seems to be working fine. Any thoughts or ideas?
BTW, I couldn't find an appropriate product category for the "What product is it about?" entry, so I picked the closest I could find.

Make sure the new pad you installed is in the right position. The pad is marked with a black dot about the size of a quarter. This end should be up for proper water flow through the pad.I fwater flow is being restricted at the pad the vibrating nosie that you are hearing is the dry portion of the pad vibrating agaist the platic housing of the humidifier. This noise stops once the pad has absorb enough water in this area of the pad.
Well, let's see what service the unit has had in its 6 or 7 years of working--
When was the Humidifying pad last changed? These usually have to be changed every year-- to get good performance from the humidifier... So-- Have you looked inside the large door?-- what does the pad look like?
When the furnace is running, you should be able to open the humidifier door, and look in, (Air should be sucking INTO the door as you open it, if the unit is properly mounted in the return air duct work..) and if the humidistat is calling -- the motor should be turning the big wheel, and moisture is being added, as the wet surface is exposed to the air returning to the furnace. What do you see?
There is also a water sump, filled by a float valve-- is that valve admitting water into the sump? Is the pad wicking up this water, and rotating into the air stream?
That pad is easily changed-- your hard ware store probably has replacement pads-- they can be sewn back on to the wheel, after removing the old one.
A bad circuit board should not make any noises. A bad solenoid valve could make a loud buzzing noise. If the noise is a squealing noise then you have defective bearings in the blower motor.
If you disconnect the low voltage wiring from the solenoid valve and you still hear the noise, then its not the solenoid valve.
sounds like either the motor is off balance
or is going bad again
either way id be on the phone to the guy who did the rapair
more than likely the set screw on the sqiral cage came loose and now its vibrating
A noisy humidifier may be the result of an unlubricated fan motor or a drive mechanism clogged by debris. Periodically clean the water reservoir, fan, and nozzle to ensure that they are clean and working properly. To keep your humidifier working smoothly and efficiently, lubricate the fan motor bearings with SAE #20 oil. Be sure to consult your owner?s manual for proper care and maintenance procedures.
If it seems loose, vibrating parts are causing the noise:
1) Disconnect the power.
2) Remove the cover and look for any vibrating parts. Tighten screws, if necessary.
3) Wiggle the fan to see if it is loose on its shaft. If it is, tighten the mounting fasteners. Lubricate the motor's bearings if suggested in your owner's manual.
4) If it still makes noise, call an appliance repairperson or take the unit into an appliance repair shop.
