Question about Patton U21403UC Floor / Box Fan

1 Answer

Turning itself off

My floor fan has been constantly turning itself off after every 10mins....It runs fine while it's on. It's all almost like it's on a timed schedule. What can I do. When it turns off I hear something that sounds like slight grinding. It's been doing this for 2-3years now. What can I do?

Well its 1 of 2 things either the winding is bad in which case you'd smell a sicky burning chemical smell, or the bearings have seized. I'm guessing the bearings are bad, there probably getting the winding too hot causing itself to short out. If its a cheap Walmart bought fan then just replace it, if not you can take it apart yourself pretty easily. You may have trouble getting the bearings of the shaft, i use a die grinder with a cutoff wheel on it, just try not to cut into the shaft, you can crack it with a hammer after your almost through then they usually just slide off. Then swing up to a bearing store they'll probably just be a couple of bucks a piece(tell them you don't care what class they are just gimme the cheapest except dolly bearings, and bring the old ones with you). Then get a piece of pipe that matches the "inner race", and carefully hammer them onto the same part of the shaft(mark it prior if there is no bearing shoulder), if there are copper wires running through the laminations (if there are any) on the shaft, tape a rag around them to prevent damage. If any of the wires are damaged on the inside of the motor go buy a new one, it'll cost several hundred to rewind it.

More than likely it's not the start capacitor why your fan will not run this more than likely it's not the start capacitor why your fan will not run this lubrication try turning the fan motor by hand if it does not turn freely it's lubrication I have answered this another post.

more than likely it is lubrication spray WD-40 into the oil holes after you have unplugged the fan of course Keep turning the fan and you'll notice will start turning more freely apply more oil to the rear of the motor as this is an oil bushing you're putting more oil into

Check that the cpu fan is working. In easynote usually you uncrew a panel at the back of the laptop. If it is not that may be a common system problem, in that case reinstall your system.
