Rainbow 2e Overheats... its the Electric Motor cooler fan......

Hi,

I have a Rainbow 2e with what seems to be a common ailment. Has anyone a solution?

The little fan that presses on above the electric motor (that cools the motor) is pressed onto a 1/4 OD splined shaft thing... Its a horrible design... Perhaps you'd heard of this?

I am ready to Attach it with PC7 while held 1/8" above the sealing surface.... Hoping its balanced well enough to stay put.

Have you heard of anyone with a different approach?

Thanks!

    RedDevil6,

    Yup. Thats what I did.... a 7mm socket or somesuch..

    the conical compression surface on the ID of the fan fatigued and split off. Dang!

    But... I managed to find some washers that fit REALLY close on the shaft, and did the PC7 thing. A one way trip, but, hey... its working.

    If it does require additional service, I will be the one with the dremel, so am not too concerned. Any idea where I might find a spare, if the dark day comes sooner than later?

    Thanks!

    John W.

It is pressed on, that is why you have a splined shaft. If you use a socket or nut driver, you can knock it ino place with a hammer. But don't hit too hard. you don't want to damage the end.

Power nozzle does not work. Light comes on on power nozzle but it does not vacuum


Many early version PN-2E power nozzles have reset buttons that are becoming faulty. The factory stopped adding the rest button to this model power nozzle so you can update your unit by removing and this my solve your issue. You have the trigger to stop the motor if you have an issue so the rest button has become unnecessary.

The power nozzle is not working and the belt seems to be in place. The motor is running fine and I can use other attachments


There are a few problems with this head which we frequently encounter.

One, the motor get's clogged up and the brushes get stuck in the motor.
The red top circuit breaker fails, and under load, the motor will stop.

Take the 2 wires off of the breaker in the power head, and short them together to find out once you have cleaned out the motor which will be a mess inside.

The belt if worn will not operate the power head if you put your foot on it and see if the brush spins.

The belt is a major problem as well as the replacement of the motor.

The motors are 45.00 CAD and belts 4.00 Cad.

The yoke on the power head also gets clogged and needs cleaned out.

Try these procedures and I hope all works out for you!

Hi, there is no reset button on a Rainbow vacuum. There is a safety switch on all E series and E2 series Rainbow vacuums, that keep it from running without the water basin on it.
If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

I bought my rainbow se vacum 4 years ago and I was using it and suddendly stoped working, I try to on no power I on and off not working at all. what shall i do is there posibility to work again.pls.help...


Hi, there is no reset button on a Rainbow vacuum.

All SE series vacuums have a built in thermal and load fuse on the motor, and if it blew, it has to be replaced, or wired directly, with out it on there.
Motor brushes are usually the source of a non working Rainbow D4 and SE and all model Rainbow vacuums and when they burn out, they usually take the motor armature with them, from excessive heat and flare electrical arking to the armature. It is probably the thermal and load fuse, that is your problem, if you did not smell any electric burning type of smell, before it quit. It could be the power switch, but not as likely as the fuse. If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

Is it common for the switch to go bad on a rainbow e series? Replaced cord but switch seems to be bad.


Not that common but more common than the cord unless a pet chews the cord or it gets stretched tight and breaks at the plug.

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.

Rainbow d4se assembly


Generic problem for all Vacuums
Rainbow d4se assembly
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.

Rainbow D3C Low suction


You might check the carbon brushes on the motor, it could be that the motor is not running fast enough, which would mean replacing the motor. With the hose off, do you have good suction where the motor goes into the vac? If it is good there, then either the powerhead isn't working or the hose is clogged.
