HOW DOES THE SPRING RESEAT FROM BASE TO FAN ON VORNADO 750?
My V-750 was packed with dust clogs throughout. I took the front grill and backside cover off, and meticulously worked with tweezers, a pick and compressed gas to clean it out. I was astounded by the huge amount and huge chunks of dust that I got of it. After cleaning the blades, grill and cover and putting the grill and cover back in place, I plugged it in, turned it on and it began making a very loud noise, like metal banging and clanging together. I thought perhaps it was ready to taxi the room and fly, so I shut it off.
I took it apart today to check for loose/broken wire in the motor or any other obvious problem. Everything looked OK, so I was able then to clean out all the dust I hadn't seen prior -- a bunch of it. I have it reassembled to the point of attaching the base to the fan.
I am puzzled as to the proper placement of the spring that sits on the base column at the top and seems to work with the niche cutout in the column. I want to make sure it is properly installed.
Can you please advise me as to do that? I appreciate any aid you can give me.
Re: HOW DOES THE SPRING RESEAT FROM BASE TO FAN ON...
Many Vornado models have a lifetime warranty - you just contafct them with your serial number and they check the warranty on your model and provide and return authorization label/number.
Send it back and they repair and return to your with a week or so.

Re: HOW DOES THE SPRING RESEAT FROM BASE TO FAN ON...
If the spring has a long tang and a short tang, the short tang goes under the clip that holds it down and the long tang goes between the stand and the back of the cowl. Tell me the model and I can send a pic of one assembled. Here is an image of a newer model 750 with the spring correctly installed.

It depends on what type of unit you have. There are grill clips on the back of the unit that you will need to depress. Some models have screws that need to be removed in order to remove the grill. If assistance is needed please call us at 1-800-234-0604.
Vornado 533 black Vornado Fan.
FULL GUIDE, DISSASEMBLY AND CLEANING. NOISE FIX.
#2 phillips head screwdriver.
Small handheld flashlight.
Flat prying tool like a flat head or a dull knife.
Small wrench, adjustable wrench, or pliers.
What mistakes I made.
I undid the screws on the axle/hinge for angle adjustment. Not nescisairy.
I tried to do the tabs before finding the three screws on the back of the fan cage.
How to get the grill off.
Get a small tipped but long phillips head screwdriver. 3 inches will likely work fine.
Position the fan to be completely level, like the normal non- angled position. Parallel with the base arms.
On the back are three small silver screws, remove each. (Don't lose them!)
Push plastic tabs on the outer rim of the back of the cage downwards, to the center of the ring. You may want a prying tool like a flathead screwdriver.
Pull off frontal grill.
To clean the fan, take off the center bolt (You will need a small wrench, but pliers may be used if it's your only option.) think the front bolt may have been reverse threaded?
Pull the fan off of the rod, notice how the rod has a flat side.
There is a small unique shaped washer underneath the fan, it has a shape that aligns with the plastic of the fan, on it's bottom face. Remember it's position. I remember it being concave outwards, but I may be mistaken.
Cleaning the fan.
I then pulled off a bunch of cat hair, and wiped off dust from all parts, especially the spinning rod part. I gave the fan a few quarter second squirts down into the crack of the rod with WD-40s.This got rid of my squeaking noise!
I then put the funky shaped washer back on, and aligned it with the plastic rotor as I slid it back onto the rod. Put the front nut back on, with washer before it. I think the front bolt may have been reverse threaded, can't remember.
I then carefully aligned the front grill with the screw holes on both sides of the grill, and re tightened the screws. Make sure you get them nice and snug, otherwise it will be loose and could cause vibrations.
There are three clips the hold the grill to the cowl.
One clip at 11 o'clock, one at 2 o'clock and one at 6 o'clock.
Use a flat blade screw driver to push the 11 and 2 positions down (do 11 then do 2) and the grill shold come off.
I can send pic if needed.

On the model I have, the front grill just pulls off from the front; there are some tabs that you might need to release by pushing with a small screwdriver from the rear. After cleaning, just align the tabs and push it back in until they click back in and latch.
After reading dozens of similar problems on here about the Vornado fans squealing (and rattling) it seems they are in need of some 3-in-1 oil for the bearings and any moving parts in and around the motor area. Also good to keep the fan clean by wiping down and removing front grill and the fan blade...A high pressure duster or spray air canister for the motor body etc. should get out any dust inside the unit. good luck!
Unplug fan. Lay the fan face down. Remove the four screws holding the stand to the base. Slide the stand all the way off the cord. Look at bottom of fan and find the small half circle indent just to left of center. There is a screw there, remove it. Go to the hand grip at the top of the back and pry out the two white rubber plugs to reveal two more screws, remove them. Back cover can now slide downward. May take a little squeezing at the center of the grille where internal clip is. Remove two screws at top of squirrel cage. Turn squirrel cage and loosen screw at bottom collar on motor shaft. Tilt the top of the squirrel cage outward slightly and slide upward to remove the squirrel cage. You can slip upper metal bracket off and set aside. Motor is held in by two screws, remove them and flip motor out of the way. There are two screws below where motor sat that hold in base of front grille, remove. Front grille has a series of clips along edges, carefully pry them inward from bottom to top and push grille gently outwards. You can now clean the rear grille, front grille and squirrel cage in warm soapy water and allow to dry. While they are drying, use a vacuum and dust rags to clean interior. When parts are dry, reinstall front grille and reinstall 2 screws. Reinstall motor with two screws. Turn motor shaft so flat notch is pointing up. Recommend to spray a tiny bit of WD-40 or a tiny dab of moly grease on shaft at top of squirrel cage, then replace upper bearing bracket on top shaft. Slide collar end of squirrel cage onto motor shaft and align screw with shaft flat and tighten. Reinstall two screws at bracket at top of squirrel cage. Align back cover just a bit toward bottom, then slide upward and clips will snap into place. Reinstall two screws in hand hold area, then reinstall screw at bottom of cover at half circle notch. You'll need either a magnetic tip screwdriver or a pair of long needle-nosed pliers to get screw in hole before tightening. Feed cord back through base and reinstall 4 screws. It took me about half an hour to do this whole process on each of my two Hawaiian Breeze fans, but they now look brand new and run very quiet.
Shall take it that you have a Side by Side setup? If so with rear cover off, when you start it does the cooling fan come on beside compressor? Also remove front grille and clean front condensor coils, full dust and hair all problems can happen. (like blocking of car radiator). Try these if fan doesn't work, replace.
When the CPU overheats then it shuts down and won't work again until it has cooled down.
The overheating problem can be caused by a faulty fan and or dust clogging the fan and heatsink assembly. If the fan does not spin freely then it is faulty and needs to be replaced. If the fan is OK then loosen the dust and vacuum the dust from the fan and heatsink.
