zero2zero4: i have a tower fan.. it can turn on.. however it takes a lot of try because
it would shut down immediately the moment i turn it on.. once in a while it
would stay on. is there something i can do? or by pass the board and use
some analog stuff instead? digital control sux.
Joseph Wolchak: my electric room fan won't turn until 5-10 minutes after I turn it on. What
can I do to fix it ?
scottyfixit: Does it make a hum when you turn it on? May just need oil.... 2 slots
usually on the top of the motor. Is it an electronically controlled fan?
Hope you get it going!
Shurupadi: Hum I could what him all day hum!!
DreadfulControversy: Twitter or FB?
Leylasmom1: What does that mean? We're having the same problem, it powers on but blows
scottyfixit: @JOEWOLCHAK1 a bad switch wouldn't be consistant of 10-15 minutes....
likely the motor is trying, but can't turn (oil or start capacitor), but
when the motor gets hot, the oil/grease becomes less resistant, or
capacitor builds up just enough charge to give the motor that extra oomph
to start spinning.... some other factors that could play a part would be a
worn cord at a spot that flexes a lot (at the plug) or wire between base
and motor... but the 10-15 minutes usually wouldn't be consistant.
wickedartglass: I have had this new one 3 weeks and it has started shutting off. I went to
Sears and bought a Kenmore hoping to have better luck. I have not heard
from Lasko since shipping the motor. I will be taking the other one back to
Walmart tomorrow. I am done with Lasko. It is sad I did like the power of
the fan. But I also like a fan that works. Seems they have been having this
problem for over a year. I am guessing they are not fixing the design
Lokidoki: The video quality is so bad I can't even see what he's doing here. Whats
samgam: I have this same fan, I went on break for a week and accidentally left it
on. When I returned it was still working. I unplugged it to vacuum and when
I plugged it back in it would turn on, and rotate, but no air pumps out!
Can anyone help???
chris soetarman: thanks Scotty, just fixed my lasko fan getting the hint from you.
scottyfixit: WD-40 is bad for bearings.... I only recently learned this. WD-40 is meant
for many things, but long term bearing use is not one of them. It turns
sticky after a while. Sewing machine oil or light weight motor oil usually
does the trick. Sometimes on the older fans they have a tiny cutout slow to
introduce oil just above the bearings, otherwise the try to find a way to
get oil in the vent hole to find its way into the bearing through the vent
holes... can be a bit tricky.
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? . Frank
scottyfixit: @ilovechefwilliam I wouldn't say that... but everyone has a specialty, and
fixing stuff is usually easy for me.
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.
scottyfixit: You Rock! Nice work!
scottyfixit: It's possible that the coil windings went open circuit. You could open and
check the leads to the motor, but I fear it's a working circuit, isolating
Steve Robinson: My fan stopped working. It Is a box fan It is very dirty. does it need to
be clean or need oil.
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.
Jennylene Smith-Drayton: No hum, no power coming to the fan. I checked the switch and cord with a
multimeter and they are both good. I am looking for a fuse but am unable to
find it. But the fan has no power and it foes not turn on. It is a nice
looking fan and I really want it to work. Found it at the street. Any
scottyfixit: My best bet.... the motor windings when open.
scottyfixit: @Myselfwannabe89: I guess it all depends on how it failed. Does it hum when
you turn it on? It doesn't necessarily have to hum the battle hymn of the
republic, but any slight hum shows signs of life. Next, when it's off and
unplugged, can you turn the blades freely or does it resist any? Cleaning
usually never hurts - I'd blow compressed air into the motor and use soap
and water to clean the blades. If you have a camera and a computer handy,
upload and link video in the reply.....
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.
emma Beckham: im havin a problem w my tower fan n i believe it might b the fuse in the
control panel,is it possible to replace that fuse? or take it in to b fixed?
scottyfixit: @samgam: Same thing happened to this fan a year later. Motor went open
circuit. Lasco has poor quality control, even on phone support with it was
originally under warranty, the american dude was just flat out
Joseph Wolchak: Thanks for your comments/suggestion, Scooty. As to your ?? The blades are
tight when I try to spin it by hand. I do have WD40. Can you describe where
I should spray / oil ? ?
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.
scottyfixit: @wander900 this one was fairly straight forward... not all fans are like
it, but it has screws in the back, and once out the case separates right
down the middle....
the2009ladye: i agree and ohk i will check it out thanks :)
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
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.
scottyfixit: @JOEWOLCHAK1: Those fans are pretty straight forward.... You've got a
switch, start capacitor, and motor in the path of the electrical
current.... when you turn it on, does it hum slightly? If you turn it on
and spin the blades by hand, does it take off then? Could be a start
capacitor on its way out. When it's off, do the blades of the fan spin
freely or do they seem a bit tight? Could need oil if tight. If you jiggle
the switch, can you make it move for a bit? could be a bad switch too, but
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....
wickedartglass: Hi all, I am guessing Lasko is having this problem with the fan just
shutting off by its self a lot.I have a Lasko Pedestal fan with remote
control. It is less then a year old. It started shutting off here and
there, now will not run more then 10 minutes or so. I called Lasko customer
service and they acted like they had never heard of such a thing. But had
me ship the motor to them and if they find it has a defect will send me a
new one. I had to have a fan so I went and bought another one.
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
Joseph Wolchak: This is Joe again Scotty, I can't hear any hum at first when I turn the fan
on. At first, last season, if I spun it by hand, it would start spinning
and keep on spinning. But now, it won't start spinning when I spin it by
hand, and the blades are tight, not loose. Could you describe what the
capacitor looks like, and where I can get /replace it ?
Joseph Wolchak: my electric room fan won't turn until 5-10 minutes after I turn it on.
scottyfixit: @JOEWOLCHAK1 weird.... hmm.... What kind of fan? A short video might help.
Jennylene Smith-Drayton: Hello. Loved your video. Have a fan that I want to fix, but it is a normal
standing fan. Not sure what to do when I reach the core. Any suggestions?
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
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!
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: If the blades are tight..... it's likely an issue with oil on the bearings.
scottyfixit: @JOEWOLCHAK1 also.... if it has any kind of electronic controller like mine
(a basic everyday fan usually wouldn't) then is could be something in the
electronics.... maybe lower than normal dc volts at the computer
controller, sometimes from weak radial leaded capacitors from either cheap
manufacturing or a small surges from the house - outside A/C units, some
refrigerators, etc. sometimes contribute to small surges when they kick on.
based on your information, that's where I'd start. -Scott
Joseph Wolchak: I got an electric room fan from Walmart. What else do you need to know,
Scotty ? It's a plain, common, ordinary everyday, 3 speed, oscillating room
fan. It won't turn when I turn it on, even with a hard push. But if I let
it on for 10-15 minutes, it'll start sometimes. It's only 2 yrs old. How do
I get it to work again ?
ssrobelot: Dear Scotty,
wander900: Very interesting video & good info on the electronics & testing for
continuity. But do you have another video on how to take the fan apart &
put it back together- or the highlights? My Fellini tower fan from Walmarts
of 3 years ago is only used for a few weeks a year, sparingly, but it's
developed a shrieking and gurgling sound on the low setting it's usually
set on. I can't see an entry point to this fan, and wondering if taking it
off its base would damage it. Tower fans are such a mystery!
