How to Identify and Fix Common Vacuum Problems ?

If the unit runs for a few minutes then shuts off, the motor needs to be replaced. Central vacuum motors generally last for 800-1100 working hours. If your motor has run less than 800 hours or activates by jolting the canister, it may be possible to extend the life of the motor by replacing the carbon motor brushes.
They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
NOTE: The reset button is located on the upper left-hand side of the unit where the low voltage wires connect to the unit. It is most noticeable when popped out after the breaker has been tripped. 3.
Another reason the vacuum is not turning on may be that the circuit breaker may have tripped. Check the breaker on the unit and if it continues to fail it usually means the motor is going bad. Another reason can be the bad signal from the unit to the wall inlet.
A damaged vacuum hose, clogged motor air filter or bad suction motor can cause the vacuum cleaner to shut off during use. A tripped overload on the vacuum suction motor can shut off the vacuum cleaner during use. If your vacuum has a reset button, push it; if the vacuum seems hot, let it cool off first.
Check For Clogs or Blocks In The Vacuum
Check the hoses, the filters, and throughout the vacuum, and clean out any blockages or clogs. Vacuums will likely also have a recommended cooldown time to ensure that the vacuum won`t overheat. You will need to wait for that time before you turn the vacuum back on.
While different factors affect how long a system lasts, many central vacuums can last 20-30 years, or even longer, depending on how often they are used.
If the motor still has some life in it, it will start, but if it is going bad, it will only work for 10-15 minutes or less. If it doesn`t start at all, it is obviously bad. Sometimes slapping the motor or vacuum unit will jar the motor and get it to work again for a few minutes. Intermittent motors should be replaced.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.
If you find that your machine is turning off intermittently, the filter in your vacuum is most likely full and covering the ventilation system. Remove the filter, then empty and wash it. Allow the filter to dry for at least 24 hours, or until it is completely dry.
Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filters need washing or your machine is blocked.

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?
Just had this same problem. I unplugged the low voltage signal wires and the vacuum stayed on. Thus eliminating the possibility of the signal wires shorting out somewhere. I’m not really sure which wire(s) were causing the problem. But when I disassembled the top housing to expose the motor and wiring it seemed to work just fine. My theory is that the heat of the motor caused the insulation on a wire to melt which was then shorting somewhere inside the housing. I suggest removing the motor housing before buying any parts or calling easy-flo. If you’re lucky like me then your vacuum should be running again in a matter of minutes.
I have a kenmore upright vacuum model #116.35922500. The agitator tube doesn’t turn. It doesn’t have a belt for the agitator. It has an overload protector. I reset it, but it keeps poping back up. Should I replace the overload protector?
The reset is for your safety no belt ,probly a direct drive motor issues ,maybe the brushes it is detecting a short and pops the reset.
Same Shut Off Problem as Hamster71
The part that you call the particle size sensetivity adjuster is bad. There are 2 seals in the assembly, the lower seal is slipping out of place because the plastic lip which keeps it in place is broken. Split housings and replace part. This machine is alot of work to take appart and get back together correctly. Might want to bring to local vac shop. good luck.
Hello, I have a problem with my Eureka Powerline bagged upright vacuum. It has a 12 amp motor and is model #4352, Type D. It was probably bought new in 1998. My problem is, while vacuuming today the motor seemed to slow down all of the sudden and then began smelling like burning rubber. I shut the vacuum off to check for blockages but could not find anything blocked. When I then turned it on again it runs but seems to only be running at 1/2 the motor speed and still has the rubber buring smell.
It sounds like a rubber sealing in the motor has come loose and is being constantly rubbed against the walls of the motor with would cause the smell and loss of motor speed caused by the fricton of rubber against the rod so if you can get to the motor try to open it and see if you can get it if not take it to a small engine repair service hope this was helpful:)
Shuts off frequently The sweeper will run for a few minutes and when it starts to get warm it shuts off. If you allow it to cool off it will turn on again and run until it gets warm
Check any filters to see if they are clogged up with dust because its overheating the motor causing the thermal switch to trip.
My dyson DC16 constantly shuts off even when battery is fully charged. I cleaned the filters to see if that was the problem. It only runs for a few seconds before it shuts off. It will run intermittently for about 10 minutes before dying completely. Please advise
Hi its Darran at Dyson.
From your description of the problem, it sounds as though there is a problem with the battery.
Your DC16 will have been supplied with a 2 year guarantee. If it still within this period, please contact our Helpline on 0800 298 0298. However if your machine is no longer covered, a replacement battery can be purchased via our website at www.dyson.co.uk/store.

I need a relay board for a Nutone CV 450 12.6 amp dual motor vacumn unit. Where can I locate one? Part #??? Unit will run by itself, then shut off. Unit wll not run at all. It has a mind of its own. Crossed a couple of wires on one of the relays and the unit runs smooth as silk. I assume its the relay, but can’t locate part number.
Why not just replace the relay? Part number 1094117…
The machine runs for brief periods, then shuts itself off. If it is allowed to sit for several minutes, it runs again, then shuts itself off.
The motor is heating up to much and the cut out switch is kicking in..You need to check the the motor filter, and worse case you may need to new motor..
