Having problems with your Broan-NuTone CV450 Central Bagged Central System Vacuum ?

I have a Nutone central vacuum model number CV450W that was working great until I recently removed the hose and it now runs continuously until I pull the plug....any suggestions please

Answers :

Disconnect the thin low voltage wiring between the vac and the rest of the house. If the vac continues to run you have a defective relay in the vac motor housing.
If the vac stops you have a short in the wiring in the house, likely behind an inlet in the wall.
If any inlets have been disturbed for painting or renos lately that would be the first spot to look in the house for a problem. Look for wires behind the inlet valve which are touching against each other or a mounting screw or against a metal mounting plate behind the inlet. Start at the last inlet used. Be careful not to loose the spring under the screws where the wiring attaches to the inlets

I have a kenmore vacuum cleaner model # 116.23612. When the hose is attached to the canister it runs, but if you remove the head to just use the hose the unit stops working. Is the motor dead or is there some type of reset or fuse. Could you please tell me how to test this. If so could you please send me instructions on how to replace the motor. Thank you in advance for your help, Tony

I have Nutone VX550C. Motor runs intermittently (cycles on and off rapidly--the light on the handle is blinking furiously) when I use the on/off switch on the hose. This happens at all of the wall connectors, so suggests a hose contact problem. Motor runs continuously when I turn it on at the switch on the wall unit.

The unit does have a switchs the PVC outlets, and it sounds like the hose mech to operate the switches is broken, and intermittently making contact. A replacement hose would likely fix the problem. Looked them up on the net, and they're not che ... Broan-NuTone VX550 Bagged Central System Vacuum

I have an electrolux epic 6500 sr. The change bag light came on, I changed the bag, now it won't run properly. If the bag is out and the hose attached it will run or if the bag is in and the hose is off it will run, but not if the bag is in and the hose is attached. Any suggestions?

First, if it runs without a bag, there's a problem with the bag lock-out switch or wiring. This needs to be replaced/repaired by an authorized Aerus Electrolux technician.\015\012\015\012First, turn dial on top of vacuum counter-clockwis ... Electrolux Epic 6500 Vacuum

I have a Model 116.35922500 Kenmore upright vacuum cleaner. It makes a loud air noise when using the vacuum. I have disconnected and removed the hose to see if anything is lodged in the hose and it appears clear. It makes the noise when the hose is connected. When I remove it, the noise stops. When I place my hand over the hose, the nose re appears. I sounds as though the noise is coming from the fan or internal parts of the machine. So, when there is a load or pull on the machine, it mak

Bosch canister vac BSG81313. Took cover off to remove lots of hair, dirt etc from running without bag in place. Everything went back together OK, but cord reel spring went zip when cover was removed. How do I rewind the spring so there is tension when the cord is pulled out ? Wound cord back onto reel, but reel just clicks ever revolution etc...no tension when cord is pulled out of vac. Bob

The spring inside the hub of the cord wheel has escaped from the locking tab. You must completely dismantle the vacuum to access the cord wheel - take it out, reattach the spring and reassemble the unit. All you need is a phillips screwdriver, a pai ... Vacuums

My Bissell BS3920F upright (similar to the 10N6F) has been working wonderfully for the past 3 years but suddenly seems to not pick up dog hair as well as it used to. It has been pulled apart by my husband to ensure nothing is blocking the hoses etc and when running the suction seems to be there. It seems to grab the dog hair and leave it in a straight line directly under the unit without picking it up. I then disconnect the hose and use to hose to pick up the dog hair. This works well but obviou

I have an Aerus Guardian canister vacuum with a clogged hose. The tiny stuffed animal toy is lodged right below where the swivel handle meets the hose. Switching the air flow does not dislodge it. I would like to remove the handle from the hose. Any suggestions?

Consider this. If your vacuum is still under warranty, removing the hose will void the warranty on the hose. I strongly recommend calling an authorized dealer/consultant.\012Although it may seem to be fairly simple to remove the handle, there ... Electrolux Guardian Bagged Canister Vacuum

Dyson DC 14 hose has no suction, with or without brush attachments. Hot air shoots out from the base of the canister when I try to use the hose. I cleaned the top filter, but can't figure out how to remove the hepa filter to clean it without destroying the case. It looks like it might take three hands to insert pennies and "flip" the case open as is suggested on a youtube video for a different model. Would this even help, assuming I could get the thing open?
