Are you taking the machine in to someone? or is this a self diagnosis??

What I mean with those questions is, sometimes it isn't the PC board that is causing the problem. Sometimes it is something else. Even the people that you are getting the PC board should have suggested some other solutions for you.

If the unit does not shut off, do not just go and unplug the electrical. Disconnect the low voltage wire on the side. Just one will do. If the machine shuts off, there may be a problem with the wiring in the house. Believe it or not, we have seen the same problem in a house that had the low voltage wires pinched, and/or over the HOT water pipe.
Another time we had found that the homeowner hooked up the wiring of the central vac system to the alarm system (in fairness, it was the same wire that was used for both) and when someone would walk past the motion detectors it would start the vacuum.

Worse comes to worse, you can always if all of the above checks out ok, is try another style of PC board. I know that there are 7 pc boards available for the unit.

Good luck and let me know what you find.

I'm looking for CV1801 Vacuum Motor, Greator Toronto... Thanks


Hello There,

I've looked up your model vacuum cleaner, and it seems that I am able to still get this motor for your Eureka central vacuum cleaner. We're located in the United States, but we can certainly ship this to you.

Here's a picture of the diagram for you;

vacuumrepair_1.jpg
We sell the genuine Eureka motor for $199.00, however you may save substantially on this motor by purchasing it under the Lamb Electric name. The motors are identical, and Lamb actually makes this motor for Electrolux, and sells the replacement parts for MUCH less money they Electrolux. We sell the motor under the Lamb name for $119. I went ahead and added this part to our site so you could place your order if you wanted to. I don't have it in stock today, but my parts distributor is showing 3 in stock, so we can easily have your order shipped out within 2-4 business days.

Here's the link to the Eureka CV1801 Central Vacuum Cleaner motor, Part number 54586;
http://www.govacuum.com/10661-Eureka-Central-Vacuum-Cleaner-Suction-Motor-Assembly-Part-54586-.aspx

Hopefully this was helpful to you. I've also left you a link below to the parts diagram of your vacuum cleaner, in case you need some visual help to see how it comes apart. If you found this repair to be helpful, please be so kind and rate the repair helpful, or leave feedback for me. I really do appreciate it, and this also helps people with the same question find the answers easier. If you have any questions, please feel free to email me at chris (dot) jones (at) govacuum (dot) com.

I am buying a central vac system, can you tell me the better of the easy flo or nutone brand. I want the one with the least problems. It appears to me that the easy flo has fewer problems, thank you


between the two brands... stay away from the nutone. If you can get it, the Beam, Eureka, or even the Electrolux and Kenmore(sears) would still be better. The warranty would be better on the Beam and Eureka (7 or 10 and one model is even 15 years)

Good luck on your purchase.

Central vac will not turn off


Base d on your description... you have a defective internal relay, value $25-30US . It sits under the lid beside the motor and has generally 4-6 low and hi voltage leads plugged into it. Sometimes this component and the transformer is replaced by a new circuit board.Tag all wires with # position remove and take to a vacuum pro shop. Original relay may look different from the new one.

Central vacuum with new motor shuts off and throws switch


Your mini breaker is probably bad if its a new motor. Its found on the relay board and they can weaken over time, especially if you had a bad motor before that tripped it a lot.

On my kenmore central vac no power unplug unit plug it back green light comes on but try turning vac on green light goes off again .


Please clarify that we are talking about the central vac LED/switch panel panel and plugging it into a 110 V wall receptacle.
If I understand when you unplug from the power source ,then plug back in the green LED comes on, looking normal ? But when you manually activate the switch on the motor housing of the vac itself the vac does not start and the LED goes out, so no green or red LED at that point?
If this is the case , Kenmore CV's built approx 5 years ago (MADE by EUREKA) and prior had a circuit board with attached cord (as opposed to detachable) which was prone to relay failure. There were several symptoms, most common was that the relay on that switch panel /circuit board would fuse on and the vac would continue to run when the hose was detached from the wall.However some I worked on from that era had exactly the same symptom you describe. If your unit is between 5 and 10 years old and this sounds accurate, you can unscrew this curved side panel relay with one philips screw. Inside on the PCB will be an L shaped black or white 24volt relay, generally rated at 10 amps. The replacement board or relay will be rated at least 24V/ 15 amps or more. If you can isolate your motor and test it separtely with a power cord or meter , the realy/board will be the only control componnet left.
If you have a small tipped soldering IRON, not a gun, you can generally find a replacement relay to rebuild the board for about $6 at an electronics parts store. Otherwise you will need to replace the control board itself, anywhere form $45 to $70 plus service call if you have a tech come out to the house, and the tech will just unscrew , detach wires and replace the board, no repair , approx 15 minutes work. This will likely cost over $100.
Please post back with your results

Nutone CV 450


If the top comes off, it will be by the motor and exhaust. Just replace it with the new one, make sure you don't mix up any wires. Also unplug it from the AC first.

Continuous running


Central vacs have relays in them, some stand alone, others mount on a circuit board. A stuck relay causes this type of problem. At the unit disconnect the low voltage wires, plug in your unit, does it still come on, if it does then you have a bad relay. If it doesn't then you have a problem somewhere in your low voltage wiring. One of the outlets, the wires may be touching or there is a staple casuing a short.

Kenmore Central Vacuum System-electrical o.k. but suction function not working. No noise from canister.


There should be a switch on the canister, for manual or automatic. Switch it to manual and see if it comes on. If it does, then there maybe a bad relay. If it doesn't, then there is a problem inside of it, motor, pc board, would have to be checked. Without the model number, not sure what components are inside without the model number to look it up.
