Re: Vacuum cleaner power loss
Http://www.geeksquad.fixya.com/ThreadView.aspx?prdid=0&thid=545672 Generic problem for all Vacuums Vacuum cleaner power loss Posted by fudpucker on Apr 25, 2008
Vacuum loses power while operating. Just shuts down and will not restart by toggling switch. After a brief (cool down?) period it will start. Is there a breaker/reset? Does it have a feature that automatically shuts it down when the bag is full? I can't locate my owner's manual, so am completely in the dark or dirt.
Hello, I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Depending on the Brand name and Model # there is what they call Thermal Switches on some of the vacuums that prevent the motor from over heating and possible burn out of the motor If the hose is clogged, the bag is full or the filter is dirty and the air does not flow threw the filter. Any one of the three situations could cause the vac to say “cut out” and stop the motor. So check with your local vac dealer. 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.

If by power loss you mean loss of suction power then I would check and either clean or replace ALL of the filters. Check and clean the rotating brushes and make sure all of the tubes are clear. Almost all suction loss is down to some form of blockage to the air passing through the cleaner and unless the air can pass freely through and exhaust properly, it will not pick up efficiently.
All vacuums generate heat and some have automatic cut off switches when the vacuum does overheat. When this happens the manufacturer does not want you to just turn it back on, they want you to know there was a problem and to let it cool down. They often do this with a restart button. Having to press a restart button is supposed to make you think a bit more about the problem and, perhaps, let the motor cool down before restarting the vacuum. The button is often small and red.
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.
Hi, Somewhere in the suction lines, starting at the cleaning nozzle up to the canister, there is an obstuction. What is happening is this. The vacuum cleaner motor uses the cool air that it sucks in to cool the electric motor. When the air flow is obstructed, the motor will over heat. There is another possibility, and that is that the canister is overfilled with dirt, or some type of powder that is clogging air flow. That can cause the same effect. To handle this, you literally have to get down and dirty. Go ahead and remove all of the hoses and attachements that you were using when this happened and look for the obstruction. Sometimes on Vacuum cleaners with a blower feature, you can blow the obstruction out using the reverse flow of air. An old coat hanger comes in handy for situations such as this. Sometimes it takes patience to do this. It is one of those things that has happened to every vacuum cleaner I have either owned or repaired. I hope this is a help to you. Let me know if you have any questions at all, Best Regards, Mark
Most vacuum motors are protected from overheating by a thermal switch that resets after cooling down. Check for blockage in the hose,
power head or a full bag that would block cooling air from cooling the motor.
Sounds like you have an overtemp switch that is tripping and shutting your motor off. Many motors use what they call a 'snap switch" ( looks like a small disk with two wires on it ) to sense motor temp and if that trips, then it will temporarily disable power to the motor until it cools down enough to allow power to be reapplied. If you are sure everything is clean and your motor can rotate freely ( if there is a restriction that limits motor rotation, more current is drawn to drive the motor thru that restriction ..which in turn will cause excessive heat build up and the temp switch to trip) ... Hope that helps!

Will restart after a few minutes, but shuts right off again... Hello, 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.
