Ken D: Thanks Scotty. Saved me some troubleshooting time. Mine blew out when I hooked it up to an inverter connected to a car battery. I guess the circuitry didn't like the irregular waveform. I soldered a couple short pieces of stiff wire in place of the fuse and wrapped a thin piece of solder around them which hopefully will protect the circuit board if a surge occurs. Otherwise I'll replace the entire circuit board with a simple on/off toggle switch ;-)
ScytheyX: lasko wind curve platinum tower fan with ionizer
I took it apart to clean it i've done it before but this time i after i put it back together about a minute after i turned it on it turned off. It only turns on when speed is on 3,when you turn it down to 2 from 3 it feels like speed 1.If you turn it from 3 to 1 the fan blade stops. If you turn it from 3 to 1 or 2 to 1 the fan blade stops spinning, but if the blade does not fully stop yet and u turn it from 1 to 3 or 1 to 2 it keeps spinning. everything seems to be fine with it accept the fan blade spinning when or how fast its supposed to. What the heck is wrong with it?
P.S. i took top off motor it is very clean i used a little wd-20 in it and where the fan blade goes into and yes when its on 1 and the blade is not spinning the motor gets hot.
scottyfixit: Back when they were built to last. Now days, it seems like people throw away working stuff because they don't like the color or style, not because it works or not.
Joshua Graham: They just dont make fans like they used to. Besides, If you look on ebay or craigslist, or go to the antique mall, rummage, garage or yard sale or a flea market, you can find and buy a nice antique vintage fan. Or get an industrial fan.
Anyway, I have used antique fans and had no trouble with them whatsoever.
scottyfixit: Lasko's support line wasn't helpful. I wouldn't recommend them, but they are everywhere it seems and I'm sure they get rebranded under other names too.
DreadfulControversy: Twitter or FB?
scottyfixit: One possible scenario, if your motor has a thermal cut off switch, it will run until it gets too hot and shut off to save the motor from burning up. That usually happens when the motor is trying to overcome increased friction, possibly from lack of lubrication. If your fan is computer controlled, there could also be an issue with the computer.
Frank Deal: Hi Scotty, We have problems with ours as well. When we turn it on, it will run for half an hour and everything shutoff. I have to unplug it and plug it in to get to work. Again, it will shutoff in a short time. Any idea what may cause this? .
Shurupadi: Hum I could what him all day hum!!
the2009ladye: i agree and ohk i will check it out thanks :)
scottyfixit: Hmm.... does the motor hum at all? If you're lucky, it just needs some oil. If the motor got too hot, motor could have a burnt winding. If it's like mine with some electronics inside, then it might an issue getting electricity to the motor. Lasko treated me poorly - not my favorite company at the moment.
the2009ladye: HEY SCOTTY MY FAN HAD WAS BLOWING ONCE UPON OF TIME ITS A LASKO ALSO AND ALL OF A SUDDEN JUST STOPPED WHATS UP WITH THAT?????
scottyfixit: By open, as in open circuit, that suggest the copper windings in the motor got too hot for the design and broke the circuit, much like a very thin floss could to a candle flame. Most motors are designed to use the least amount of materials necessary to achieve low production costs and be super energy efficient as compared to an overbuilt motor. A motor that's on but not rotating can transfer that energy into a spinning shaft, forcing transformation to internal heat, as not designed for.
Leylasmom1: What does that mean? We're having the same problem, it powers on but blows no air.
scottyfixit: A mechanical timer, I presume? How long have you had it? I'm not familiar with that brand, nor is google returning any results on the brand name or model number. You can get an add on in-line timer that allows you to plug the fan into and for it to cut power to the fan after preset time.... if you're up for a quick fix....
l4luc: hey scotty, sup? I have a prinston HF-T291 tower fan which stopped workingsome days ago. I'm pretty sure it's nothing about the fuses, since it stopped working when I programmed it to stop in 1h, like I do every night. it's not like the one in the video. the speeds work with buttons, but the timer doesn't. it's like the timers in the classical microwave. I think it broke while i was setting it. however there's a black box that won't let me separate the top and fix it. what can i do?
thanks a lot
scottyfixit: My best bet.... the motor windings when open.
ssrobelot: I opened my Lasko 48" tower fan. It doesn't appear to have any changeable interior parts. The fan is getting power as it beeps when I turn it on and the oscillating function works. Just no fan air.
ssrobelot: Dear Scotty,
scottyfixit: I believe those are soldered in.... basically making them not user replaceable. They designed most of them to be thrown away when something goes wrong, but ff you're not afraid of the soldering iron... it can be done pretty easily. Most repair shops will charge you more half the cost of the replacement, which often renders it not worth fixing, so you'll have to weigh those options. Good luck!
