Re: What Causes Living Fan to spin slowly?

Maybe the axle that the fan spins on is out of grease or similar? or maybe there's something clogging up the mechanisms of the fan such as dust? I really don't know to be honest because this is the first report I've heard about a fan slowing down. The fan in my living room was purchased when I was born in the early 1990s and works like a charm until this day.

Thanks.

agree with you, some old stuffs are still great. one of my fan in my house , KDK is still working great, about 10 yrs.

Just that I had some couple of cheapo fans around and the fan speed is greatly reduced

Re: What Causes Living Fan to spin slowly?

sounds like the oil gummed up and caused too much drag.
does it run better after it warms up?
if so take the motor apart,clean the bearings and their packing with brakekleen,
let dry and oil with a good oil .i use mobil 1

Re: What Causes Living Fan to spin slowly?

i had oiled it and same result

the speed is still the same,
like I set to 3 mode, the fan speed is like on power one mode.

wow .... mobil worr... how about WD-40 have any kicks?

Re: What Causes Living Fan to spin slowly?

I have heard that WD-40 has a limited effect because it is water based. Basically it dries out, this is something that is not desirable in a fan. That is what I have heard, not sure if it is true. Grease or good quality oil should be pretty good thou.

Re: What Causes Living Fan to spin slowly?

WD40 is an solvent, based on diesel fuel. It does evaporate within days or weeks and then it may be worser then b4.

So don`t use it alone, only use it to thin a thick oil, to get it into the bearings or to clean something.

Re: What Causes Living Fan to spin slowly?

does it stop quickly when you shut it off?
if yes its gummed up.
if it coasts freely look for a bad cap.

btw the caps is in black rectangle plastic casing, with two terminals on the top... i dunno what is the proper name for it ... hahas
