I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Not knowing the brand name or model number of the vacuum, some vacuums have a thermal switch or thermal shut off switch to protect the motor and once the motor gets hot the vacuum will shut off, or the vacuum could very well be clogged and the air is not getting through to the motor to keep it cool. Please check your owner’s manual under the trouble shooting section or cal the factory / manufacturer to see if the can send you an owner’s manual (OM) or you can download the OM from the manufacturer’s website. Next time include the brand name and model #. ? So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

It was working fine and them just stopped it is not that old and was not making noises HELP!!

Vacuum cleaners have electric motors in them that require proper airflow to pass over them to keep them cool. Many vacuum cleaners have a thermal (heat) sensitive shut off mechanism built in. This mechanism should prevent the burn out of the motor. If you run a vacuum too long with a clogged hose or clogged filters (especially bagless vacuums) or clogged bags, that is essentially choking the vacuum for air and not allowing it to breath properly. This will cause it to overheat and shut down. Most of the big box store purchased vacuums have very thin wires in the motor windings and can only do this a few times before the motor completely fails. If your vacuum has been shutting down, then cooling off and restarting after about 30 to 45 minutes, then shutting down after only a few minutes of use, your machine is probably clogged up or the filters are compacted.

The vacuum cleaner works for a few minutes then shuts off.After a few minutes it will start again,but soon shuts off again.

There may be as many as three air filters in the vacuum. Remove and thoroughly clean all of them and try again.

My Hoover U6458-900 shuts off after a few minutes of vacuuming. I let it set a few minutes and it will start up again.

It sounds as if the motor has overheated at some point, and damaged the thermal protector fuse in the motor compartment. Clean the filters thoroughly, change the bag, and try to operate it. If it still shuts down, the thermal protector will need replacement. ( Part # 47534032 )

Hi Cassidy. You are probably right about the motor overheating. The usual cause for overheating is a clog some where on the bottom of the machine. Check for anything that could be blocking the dirt fro going into the bag. Hope this helps Chris

I know nothing about your particular vacuum, but many vacuum cleaners these days have
safety cut out's, which causes the motor to do exactly what you describe. Sadly blockages, faulty switches, over stretched cables, carbon brushes etc could also give similar symptoms, so sounds like a job for the repairer on this occasion. Get a quote first if you can.

My Hoover runs for a few minutes and shuts off.

It's possible the thermal reset is defective. It shuts the motor off if it gets hot. Remove the bag door and take the bag off, remove both filters and then turn the vacuum on, just leave it sit there with the motor running. This eliminates the bag or filters causing any airflow resistance. If it still shuts off after a few minutes it's likely the thermal reset is bad. Some vacuums have an external thermal reset button which can be replaced if necessary but on your model it is built into the motor and you must replace the motor. If the motor runs fine put the bag and the filter under the bag back in - (make sure the filter is clean and not restricting airflow) put the bag cover on then turn it on again. If it overheats and shuts off then you may have a clog on there somewhere restricting the airflow. If so check the power nozzle area, the hose coming from the power nozzle, the extension hose and wands for clogs or restrictions.

check all filters, if they can be washed do so, if not clean or replace. next check for a clog in the machine and in the hoses. the machine as a thermal device that if it senses an overload or getting to hot, the machine will shut itself off for safety resons.

Dyson shuts off in 5 minutes, then starts up 2-3 minutes laters w

I think there's a good chance of a clog that you haven't found. On the Dyson it's fairly easy to remove several covers that give you access. From the collection canister is a tube that runs toward the base. At the bottom of the tube you can remove a cover where you can check for a clog. Thats basically on the right side of the machine. From the rear side, very low and toward the middle right is a tab that you can push in and remove the tube that goes up into the flexible hose. Thats another good place for a clog to hide.

Hoover mach 5 only used 3 times

If the filters are ok, and there is no clog in the hose or dirt inlet down by the brushroll, then the motor protector is probably bad.
