I have an easy flo vacuum model # 199C and it won't shut off. It started out as an intermitent problem but now will not shut off when the hose is unplugged, nor when the off/on switch on the main unit is shut off. the only way to get the motor to stop running is to unplug the unit. Any ideas?

Seems like your unit goes into failsafe because it detects something wrong. Well you should check the brushes and replace them if they are worn out. Also check the wiring for shorts etc, becaue the unit maybe tripping due to an overload. The printed ... Bissell Vacuums

I have a vx550cc that keeps kicking in and out quickly, then shuts down for a few seconds and starts up kicking in and out again. There is lots of suction at all the outlets and sweeps. The dirt bucket has been emptied and the filter cleaned. Al the LED lights light up when the motor kicks out, then back to one green when it starts back up. This unit has worked great for four years with no problems.

Hi thereAll Dyson vacuum cleaners are fitted with a thermal cutout, which will switch off the motor if it becomes too hot. This is normally caused by a lack of airflow to the motor, i.e caused by a blockage or a dirty filter. ... Dyson DC05 Cylinder Bagless Canister Cyclonic Vacuum

Power nozzle on E-series won't start when cold unless the red 'reset' button is pressed multiple times while also holding the trigger to 'warm it up'...this is w/the power nozzle off the floor - no restriction on it turning. Once it's been running and then turned off the button must be pressed w/the trigger to get it to run - again w/the nozzle off the floor. It also seems to shut off too easily while vacuuming. I replaced the motor,which didn't fix it. Is the reset switch next on my list? T

My Hoover Windtunnel Ultra U6425-900 began shutting off after a few minutes of vacuuming. The time interval became shorter and shorter. If I leave it sit a while, it will start again. This does not happen when I used the attachments - only with the floor brushes. The switch has recently been replaced and the whole vacuum serviced by a Hoover dealer about a year ago. I have been told by a local repair shop(not a Hoover dealer) that it is the motor, there is nothing to do other than replace t

Central vac system is 18 years old. Recently started to shut down during vacuuming. Motor may be over heating. Electrolux has been out and is pushing a new system but not sure if it is necessary.

The motor can be replaced for a lot less than the cost of a new machine. A new motor comes with a one year warranty if installed by the service tech. A new CV unit alone may be over three times as much, but does have a five year warranty.\015 ... Electrolux Cs 3000 Central System Vacuum

I have a Hoover, Steam spin scrub, Model F5897-900. Only used it a couple times and the motor gave out. First started being noisy then a bad smell. It did seem noisier that what I would expect from the start but I didn't realize it was a problem with the shaft of the motor. I took it apart and found the motor shaft wasn't true and causing sparks. The motor looks like it can not be taken apart and repaired. This seems like a default from the beginning but it is past warranty. Also noti
