Question about Eureka 437AZ Bagless Upright Vacuum

1 Answer

Main Vac No go

The main vac motor will not operate. The sweeper motor is ok, I have found a gizmo attached to the black wire going to the moter to be open. I suspect this is a thermal trip of some sort. How can I get a new one?

Hello jb1720.. Here is a link to the users manual... they do not identify the internal electrical components within your vacuum but they do provide contact information ( phone numbers etc). In all probability, you are correct in your assessment that you have an open thermal fuse ( probably non-resettable) in series with your electrical supply line. If you have a local appliance repair place near you, I would take the part with you and see if they have a replacement readily available ( which they probably will).. That may be the fastes way to get one.. Or.. you can use the contact info above to speak with a rep from Eureka.. Hope this helps you..

Electrolux cyclone power 1900w no suction with main attachment

If you've tried several different attachments and they all exhibit the same poor suction problems, you should completely check the parts of the vac that are common to all the parts that have the problem.

Since the motor creates good suction without attachments, I suspect the problem is the hose. Either an obstruction or a crack. Typically, if you block the end of the hose, the pitch of the motor's sound will go up slightly - like it it is spinning faster (it is). You can keep removing parts from the vac intake until the motors sound decreases - and that will indicate the part that has the obstruction. If it is a hose, you should clear the obstruction with a "snake" or other object like a pole.

If the motor sound does not change, then there is likely a split or crack somewhere between the intake of the vac and the device. You'll have to check it carefully - or if possible - connect it to the output of a vac and seal / cover the end. Feel along the length of the hose, etc. for air being blown out. Repair the opening and you should be "good to go"

Good luck!

Our dirt devil bagless upright (110002) stopped working while vacuuming. we cleaned everything out and cannot get it to start again. the motor is warm, but does not smell hot. is there a reset...

Hi, no im afraid its not that easy, the problem is with the wire that goes into the vac from the mains, now you see where the mains lead goes through in the back of the vac well what happens is when you vacing and moving the vac around this part wears and causes a short or loss of connection, now it usually happens when your using it then the free cable runs out and it pulls on the vac when you try goign further than the wire reaches, so the problem you are having is with the connection between the wire and the on/off switch, this is a very common fault with all vacs of this type.

to fix it your going to need to remove the cylinder and see if their is an access panel on the front of the vac behind the cylinder you take off to empty.

how ever if you have no electrical skills then its not safe for me to tell you how to do this repair, if you get it wrong you could do harm to anyone who uses the vac ok so be warned i have told you this ok.

the work involves removing the panel the other side of the switch then you need to undo the wires going to the switch you then need to pull the mains wire out of the vac so its no longer connected then cut it back 3 or 4 inches so as the part that is faulty has gone then you need to fit it all back together the right way round and make sure their is no bare wire showing and that it is all secure and then it should work.

but before you do all that check the fuse in the plug first as if its got hot this fuse may have blown so i would check that first before you decide what to do next ok.

it wont cost much to pay someone to do this as it wont require any parts, if you could take it to a reapir shop yourself then that will be even cheaper as you wont be paying a call out fee, also check if you have any warranty left on it as this fault wil be covered

let me know how you get on or if you need further assistance ok

please can you rate this solution as i have a whole page of unrated posts, thanks

Have an electrolux 2100 canister vac, it has lost suction power thru the years. no clogs in newer hose or in sweeper. even with new bag, filter and belt only increases power minimally.

Have you ever over the years replaced your brushroll ? Have you tried dropping a coin thru the hose from one end to see if it comes out the other end ? Have you taken the wand loose from the elbow ( the swivel part of your carpet sweeper) to see if there was a blockage ? Does the motor make a strange noise ? Have you ever had a tune-up on your vac.
You might think about taking your vac to your Aerus/Electrolux shop.

My vacuum is constantly shutting itself off. When

It sounds like you have a blockage somewhere and the air is not passing over the motor to keep it cool. There is usually a thermostat mounted either on or near the motor. The blockage can be anywhere from the elbow ( the swivel part of your carpet sweeper if you have a canister vac) up thru the hose.If you have a canister vac, use a broom handle to push through the hose to clear the blockage. DO NOT ! use a coat hanger or anything that will cut or tare the hose. There are electrical wires in it that have 120 volts and causes quite a shock !
If you have an upright vac, start with the duct hose that comes from the part with the brush up to the hose and on to the main canister of the vac
If this does not work, take your vac to a reputable vac shop for repair. Hope this helps,

The upstairs portion of my cetral vac works fine. the downstairs portion never has worked.

There are two components involved here, wiring and pipe.
Have someone go to the vac and turn on manually, briefly while you go to an inlet on the lower portion downstairs and open the door. Then shut the vac off.
If you have suction downstairs at this point with the vac turned on manually , your pipes are all connected and the issue is the wiring for the lower level of the house. It will need to be connected to the wiring from the upper level. A good installer will have roughed in the system with the necessary wiring running along the pipe from each inlet. You should find a piece of wire hanging beside the pipe at each of the lower inlets. This low voltage wiring will need to connect to the main line by colored sequence. Your problem may be as simple as a bad splice where the wiring connects to the main line , or a second wire hanging inside the wall behind an inlet which has either come loose or been omitted. Do not unscrew the connection screws at the back of the inlet screws fully where the wires connect as they contain a spring loaded terminal which may fall apart.

If you have no suction, the piping has either not been connected to the pipe from upstairs or your lower piping is clogged. You will need to trace back and find your main floor "drops" in proximity from below , then connect them into the balance of piping for the system, being certain to connect the wiring at the same time. Post back with what you find and if you need more help.
Last of all if you actually have moderate suction on the lower level, but not enough , you may have blockage in the lower line or a leaking valve door upstairs. If clogged you will need to use another vacuum a ad draw the blockage out at a lower floor inlet, generally the one closest to the vac.
Please post to confirm what you have found.

Do not turn on again. You have an obstruction in the fan . You will need to remove the motor from the lower housing, dismantle the fan cover and remove the obstruction, possibly replace the fan as well.
The lower housing plate can be removed revealing a set of clamps around the motor hosusing which will in tun release the motor from the base of the vac.

Kenmore vac producing burning odor

It sounds like you have bad carbon brushes on the motor. Get replacement brushes from a local vac shop, and take the unit apart. On each side of the motor their is a retangular piece of plastic with what looks like magnets in them. In most cases they are simply held by 2 screws. Replace these brushes and reasemble the unit. If the problem persists you have burned out the comutator on the motor and the whole thing must be replaced.

Need new switch for Shopvac QSP Pro 10 gallon unit

I just went through the same problem with a Shop Vac. The switch is easy to replace but not easy to find. After removing the switch, I found a match made by Sigma Switches. They directed me to contact a local RV dealer and look in either their Coast Supply or Stag/Parkway Supply catalogs for the appropriate switch (an H2-28 in my case for a QPL45 Shop Vac). After ordering the switch and $5 later, it snaps in like the original with no problems. Certainly beats $70 for a whole new motor assembly.
