That fan has an electronic (computerized) control board which sometimes malfunctions. Nothing new there, right?

The problem is that the cost of the repair can excede the price of a brand new replacement, with a warranty to boot.

You may take it to a service depot and get it checked out, provided you get an estimate and this is done free of charge.

I had that problem with 2 fans of that model. I removed the fan cover and vacuumed out dust, pet hair and then loosened the fan lower drive attachment screw, and the top cover and upper bushing mount. Lifting gently upward while pulling on the fan lower axle from the top, the fan cylinder can be slid back and removed. This exposes the motor drive spindle. After cleaning the spindle area, I supported the assembly and temporarily plugged the unit in and confirmed that the motor was stuck and would turn if assisted. The manual Control unit worked and the remote as well. After cleaning and treatment with light penetrant followed by several drops of lubricant the unit worked fine with no resistance to manual rotation and fan coasted easily when assembled and powered on and off. It may not be a permanent fix but shows quick responses to speed changes and a forceful air flow now. Good luck!

My QL60 just stopped sucking. The motor and fan run fine.


If the fan is running there has to be suction. If there is none it is because the air in entering via some other port and bypassing the normal intake. Check it out. Check hoses and fittings.

What can you do to stop squeaking when I'm winding bobbin


Spray wherever the squeak is coming from with a dry silicone lubricant called 'Jigaloo' or WD40 Dry Silicone Lubricant. It is also great for sliding windows.

No suction


I presume the motor is running, take the front brush roller off and check the fan is still intact. Possibly broken fan.

often at good hardware stores. there will be a box or drawer with a variety of replacement knobs in it. these are generic knobs designed to fit a wide variety of things, so try and find the drawer or whatever. it may be in the electrical section or it may be with the oddball screws and nuts and things. It's there, but dont ask if they have a replacment knob for a lasco fan, just ask for a selection of replacement knobs Hope this helps, if it does please click the thumbs up

This is used in a Lasko 2155A window fan. It is best to buy an entire new unit. The motor does not seem to be available anywhere.

Motor still runs--sounds like jet engine. do I need a new motor? or is there some sort of muffler that has malfunctioned? vacuum belongs to disabled mom---so trying to do work ourselves--cant afford much....


This little vac I think is actually made by Samsung. If it is ROARING and vibrating, either the bearings or suction fan is in bad shape. Remove the lid as if to inspect the belt and see if there is a visible intake opening with a plastic fan rotating inside. If so you have to inspect for damaged fan blade . A broken blade will cause the noise you describe and can be fixed on most vacs by carefully opening the fan housing and unscrewing,the fan from its threaded shaft. Then screwing on a new matching fan. Post back with more info and I`ll try to walk you thru the process

Hoover upright has stopped working and tripped the circuit breaker. Where is the fuse located on the hoover ?


Most Hoover uprights do not have fuse. Some canisters doe but it is a thermal shutoff. When the vac overheats and cools down it restarts on its own.
You very likly have motor damage, but if lucky you could have an obstruction in the fan causing a jam. Do not attempt to run again.Lift the lid off the vac and see if the drive shaft for the belt will turn. If not motor will need to be removed and fan housing and intake area inspected. If the motor shaft turns and you hear scratching or clicking, the carbon brushes are likely damaged often requiring a replacement motor. If the fan is jammed you will need to dismantle the fan housing. Remove the two motor clamps and there will be four screws on the side of the housing to release the fan cover. The fan should rotate freely in your hand.

Motor runs fine and hose not clogged will not pickup dirt


This may sound silly, but have you checked the belt? A lot of Eureka vacuums use the vac motor to run the brush, and if the brush is not running the vacuum won't pick up. Another thing to check is the condition of the fan blades.. if they get worn they will push air out of the exhaust ports, but not push enough air to pull the dirt into the vacuum bag. Another thing to check is the length of the bristles on the brush... you can change a lot of the bristle strips and save the cost of a whole brush roll.. All of these fixes are under $10.00 (Belt: $1-2, Brush Strip $3-6, Fan $5-10) at most places.

Changing fan


My solution is one that only works if the vacuum is a spare... To get mad at it and throw it in the garbage...

My thought though on what the problem actually was... Seeing as where the vacuum came from and what the problem was, that it was run with the fan broken causing more damage to the motor and therefore making it impossible to fix with just a fan. I would suggest that if your vacuum sounds different than it has before, stop running it and see if there's something you can do to fix it and if not then don't keep running it. Coins are the main problem with a broken fan and are not made to be sucked up by a vacuum cleaner.
