How to assemble correct movable fan gen., middle fan spacer, rexair d4 lower stage fan and so on? Which side goes first?

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
You can change the fans on the RexAir / Rainbow vacuum but sometimes that is only a temporary fix, the fans would be new but the rest of the motor may burn out sooner with the added load to the motor and sometimes it is more cost efficient to replace the motor than to repair it and have it break down or burn up the motor, as far as the spacing
You can refer to the nearest vacuum cleaner dealer in your area or in the yellow pages or call the RexAir/Rainbow factory for a schematic of the breakdown of the motor, and you can also cal the factory or check the website and download the owners manual from the website.

How do I replace the fuse on a rainbow vaccum?


The D4 model Rainbow has a Thermal Cut Off
This has to be manually replaced. It is attached to the Field 120v D4
If this has blown, then most likely something is causing. The Armature Tall 120v D4 could be going bad.

Will D4c se plug into D4c


The Rainbow D4, D4C and SE all are the same vacuum base, only changes were made to the nozzle. As long as the nozzle cord on your D4 has 2 prongs, not 3 prongs you can use the D4 nozzle that looks like This or the SE PE (SE Performance) Nozzle that looks This

How do you replace the top shell of the Rainbow D series? It doesn't look like the wires can be disconnected without cutting.


To replace the top cap of a D4 Rainbow vacuum:

Remove the separator.
Remove the 4 screws on the bottom.
Pull the bottom off around the foam tank gasket.
Remove the next 4 screws.
Carefully pull the wiring up through the middle section wire hole.
Remove the top cap 4 screws.
On the bottom of the switch there are 4 fingers, one on each corner.
Push the fingers towards the center of the switch and push the switch through the rectangular hole
Pull the wire through the middle section and the top cap to give you as much loose wire as possible.
On the long sides of the switch near the wires are 2 small round holes with small semicircular tabs pushed through the sides of the switch assembly. These tabs hold the wire assembly in the bottom of the switch. Very carefully push a jewelers screwdriver between the switch body and the wire assembly on each side simultaneously to release the tabs and pull the wire assembly from the switch body. BE VERY CAREFUL. Do not pull the wires hard. The wires are held in the wire assembly by small friction clips. They are not soldered or attached except by the friction clips. These friction clips fall out very easily. The twist in the wires alone will pull them out of the friction clips. So hold onto the wires in such a way that they cannot twist free. If you loose a wire or two, you will have to push them back in and reset the friction clips. This was a challenge of dexterity. During factory assembly, The wires were probably pushed one at a time into the bottom of the completed assembly. You could record the position of each wire and replace them as the factory did. This was the most difficult step as the switch came apart very quickly and without warning and the wires very nearly separated from the switch assembly.
Remove the old top cap from the wires and replace it with the new top cap. A 3rd hand may come in handy.
Push the wiring assembly back into the switch body the same way it came out.
Push the switch back into the top cap.
Reassemble the vacuum.

Rainbow se trying to fix


small red washer on top - motor is the top. Also on only everyother fan spins.
Small fan with the small hole up
Barrel Spacer
Large Fan with the the hole down
Hour Glass spacer - this spacer has a washer welded to the bottom of it - spacer down!

Hope you changed the bearing while you were where here.

Give it a spin by hand and make sure there is no grinding.

Hope this is right, doing it from memory, have a picture at work.

Older Rainbow Noisy
Posted by Capt_Troll on May 06, 2008
I Have an Older Rainbow (i think it's a d4)
my Old roommate ran it once without water.
it Still works now (with water), but
it's Very noisy on start up
Also I Can't seem to remove the separator (no instructions) but the nut at the end of it appears to free spin the motor when i try to turn it.
Can I Take this apart and Clean/lube it? And if so how? Or is this thing on its last legs? Thanks



Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Rainbow E Series Canister Wet/Dry Vacuum. The Rainbow D4 is an older Rainbow Vacuum and the part where the separator is part of the armature, the separator should be able to be removed and that might be one of the things making noise. As normal maintenance the separator should be removed and cleaned after every use and re-installed, then place a newspaper or towel under the motor unit and turn on the Rainbow and spin the moisture out of the motor unit. This should be done every time you use it. Other wise the Rainbow has 3 fans in the bottom of the motor and if they are weak they will make noise from the motor unit as well. Watch out… the repair of the Rainbow D4 may exceed the cost of a new motor of which will solve your problem of noise and separator --- compare the cost and the labor and make a decision. If you have further questions please feel free to contact your local vacuum cleaner dealer. . So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Motor replacement for Rainbow D4se


From the bottom, remove the screws separating the top and the bottom. Then at the bottom, remove the round water seal, take out those screws, ( careful with the water seal, reglue it with contact cement when you put it back on). At the top of the motor, take out the scres around the motor and it should pull out.
