After vacuuming my two bedrooms on the top floor of my house and turning the unit off using the switch on the portable hose. I later changed attachments to vacuum our hardwood floor, only to find out nothing was working. I went down to the canister noticed the power indicator light was not on. Pushed the power button, nothing. Checked the fuse panel, it was good. unplugged the canister and plugged it back in, green light came on. Plugged in hose attachment to the central vac plug switched on noticed the power light went out on the Central vac canister.\ about 20 sec after switching the power switch on.
Took the Canister top off, no smells, no carbon, fuse is still good.

Re: Central Vac will not turn on.
These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.

Many central vacuums have similar or the same parts made by a small number of manufacturers. I found the MD Central Vacuum website to be very helpful and I hope it solves your problem. I have attached pictures and descriptions from their website so you can see if this is what your wand looks like. If so, to separate the wand from the floor brush unit there should be a lever or button on the brush housing you can push with your foot to release the wand. If you are asking about where the wand connects to the hose you push that black button that you see at the top of the wand in the picture, the top smaller black part. I hope this helps.
Broan 450 air-watt and 8.5 amp power unit. Covers 3,000 sq. one 30-ft. crush-proof hose with on/off switch, one 10-in. wide hard floor brush features swivel neck for easy maneuverability around furniture. My new home is just under 2000sf. Will this new unit have enough suction?? Just buy or don't??
Well, for this unit you will need any of the following bags,
Eureka genuine Part# 90610 Eureka replacement (Central vac bag) another genuine bag style called CV-1, and/or CV-2 Kenmore Central vac bags
Most of the bags there are available at your local vacuum shop, and sometimes even Sears. The Kenmore central vac bag is, can and will fit your Eureka Mega Boss. Prices range on these bags anywhere from $12-$20 for packages of 3. Generally you will replace a bag once every 3-4 months.
You have a defective internal relay on the vac. Check for warranty coverage as this is a common occurrence on these big box store units. If beyond warranty the relay should be a straight forward unit, miniature circuit board type plug in device. Find a Broan Nutone service center or take to vac pro shop for parts.
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
Try to plug the hose in sideways. So the top of the hose is rotated 90 degrees. If the unit turns on then there is something wrong with the hose. It might be a short or it could be a bad switch on the handle. If the unit still wont turn on I would think that maybe the low voltage wire got disconnected from the unit or there is a break in the low voltage wire somewhere along the way. Let me know if you plugging the hose in sideways works.
Sounds like the relay that is in the central vac unit is stuck to the ON position. When you plug it back in..does it start right up ? If so.. You should be able to disconnect all the receptacle feeds to the central vac unit at the central vac unit to determine which one ( if any) is calling for the vac to stay on.. if none are.. then it is internal to the vac and may be a stuck relay... Hope that gives you some ideas to check...
http://geeksquad.fixya.com/ThreadView.aspx?prdid=0&thid=567634 Generic problem for all Vacuums I have a 3 year posted by patfitz on May 03, 2008 I have a 3 year old NuTone CV 353W central vac system and recently the switch on the hose handle does not turn the system on from any outlet in the house. I have to plug the hose into the outlet and then turn the unit on from the switch on the canister. Any help would be greatly appreciated. Thanks Hello, I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. There are a couple of things that come to mind, 1st. you may have a bad switch in the hose and in most cases that can be repaired – if not you would have to purchase a new vacuum hose. 2nd. You may have a bad inlet valve in your hose and most of them are low volt of which would only cost less than $10.00 and can be replaced yourself unless you have what they call a SuperValve of which has 2 low volt wires and then it is wired to your home electricity and that should be replaced by an licensed electrician. It is a low volt and high volt inlet. #3. the last thing you may check id that you may have a bad relay in the canister itself. Because you should be able to turn on the Central Vac with the switch on the hose and everything should work just fine . feel free to contact your local vacuum cleaner dealer in your area of call the Nutone Factory cust serv line for further assistance.
