I also was having a problem with my fan coming on and then turning off and even when I would turn it on by remote, it would turn off on its own a short time later, it never had any real specific time it would run. Then I read here about a fellow talking about the type of fuse in the plug. I checked my plug and sure enough, it also has a fuse built in. But knowing how specific electric currents run and the cycles they like to run on I moved the plug to a different outlet on the extension cord and it has now run for over an hour without turning off. This is something that occurs more often now due to different electrical parts in devices now. I first learned about how some appliances prefer a specific hertz of electricity to operate. For the past several years I have run into the same situation with different devices ranging from fans to laptops and desktop computers and TVs. If you plug something into one of the outlets of a surge protector and it does not turn on then go to a different outlet till you find one that the hertz is operating on the preferred hertz for the device. I have even run into the problem of the computer working and then just plugging something new into the surge protector will disrupt or change the hertz of the outlet the computer had been plugged in and would not power on again, I just plug it into a different outlet and it powered on. What happened with my fan was I had plugged a laptop charger into the same extension cord and it must have changed the hertz on the fuse plug and causing it to get hot and cut the power to the fan. Then when it cooled down it would return to the previous setting of the fan which was on and come on.
If it has a timer setting adjust or turn it off
other than that have it checked for an electrical fault by an appliance repair shop

open it. look for a wire that has become disconnected from careless factory assembly

I have a Lasko HVB, but this might apply to your fan:
Without taking the thing totally apart, here's an idea you can try: The power cord on some models (like mine) has a "warning" tag. I had the damn thing all apart when I noticed this. (Well, who reads 'em??) Seems like there's a mini-fuse in the PLUG itself that, when it blows, there's nothing you can do about it except send it for repair to a factory authorized yadda yadda yadda. Who's going to do that??
If you plug in and NOTHING HAPPENS, here's what might turn out to be an cheap and easy fix: cut off a few inches of the plug end of the cord and go buy another plug at Ace. Heavy duty might be appropriate: don't think I'd want a lamp plug on this baby. Get one that's easy to install. Bring the cut off piece and they'll help you find exactly what you want.
If you want to open it up, there's a screw behind the Lasko medallion, remove that and you can snap out the grille. You can see where the cord comes in from the back of the blower housing. Test the line voltage. If you're not getting about 120VAC, it's the plug.
If that's not it, IMHO, without some knowledge or a schematic, you're screwed. That'd be me. It wasn't the plug.
Good luck!

The bearings on the motor are dry and need oil. It's really not made to be oiled, but you may be able to take it apart and get some oil to the bearings if you want to mess with it.

It has a timer on it & it is set off. The one time we did use the timer, that's when this problem started.
