No swing, swing noise, fix it for 175Baht (swing motor), 3 screws and 2 wires, 10 minutes.

You are paying way too much, checked my recent order from Lazada (KSPTHAI shop) and the swing motor was 58baht.

Crossy,  at what stage do you give up on a fan ?

 

If it's going to take more then 15 minutes to diagnose and repair (it's not like there's a lot to go wrong) then it gets consigned to the "breaking for spares" pile (blades, cage, mouldings).

 

What usually happens is they start to look too tatty for Madam's liking and so are shipped off to the family dwelling where they live out their twilight years ???? Or get completely wrecked and end up in the skip!

Yeah, there's an errant "1" in there, the last lot were 75 Baht ????

So you waited until four fans needed fixing?

I suppose doing jobs in bulk saves some time.

 

More a case of putting it off until the black looks from Madam become too regular ????

 

We had a leak on the water pump, just a drip. It started when I moved the pump during last-year's flooding! I fixed it in April. It actually only took 20 minutes!

 

Her indoors just told me the outdoor fan is dirty. I hadn't and still don't notice. Apparently that is the problem.

Now I try Mitsubishi

I've got two and really impressed.  Uses less electricity with a quiet brushless motor for quiet operation.

 

Easy to clean. 

 

I use it at the foot of the bed along with Aircon.

That's almost certainly a failed run capacitor.

 

10 Baht and 5 minutes to fix ????

I have had them almost stop spinning or rotating very slowly, found out take the coves off and put a drop of 2-strok oil, on the motor bushes, they get dry, front and back, or Boots as Thais call them, normally works. 

Have had some bushes replaced in one fan, local guy did the job 200 baht kept the fan going for another 18 months. 

Comparing a Sharp brand  fan a Atari fan don't deserve the name to be named a good fan ....cheap ...yes ????

Sharp a very stable fan with a long wire ????

I wish I could buy them here in my E.U. home country ????

"If you are really skint then there are chaps in Ban-Mo who re-wind the motors sitting by the side of the road!"

 

Reminds me of my days working for Ampex where there were rooms full of women operators who sat all day looking under a microscope and winding nyleze wires around the ferrite video heads. Yes, it was a woman's job as men didn't have the patience for the repetitive and tedious work.

Crossy ....   a  new 16"  motor is 300-350 baht ..... then I have to install it ...  

 

a new fan is  444 baht,   I know what I'm going to do ....  haha

Your truck has a bad fever. It needs fluids and plenty of rest.

Over the years I've done the oil trick, replaced motors, replaced this spinning gear thing 

and replaced this plastic 

Like Crossy, when the fan is on it's death bed, it's stripped for parts or sent off to the inlaws.

I regularly, dismantle ,clean and oil our fans ,  replace any faulty parts , have

some that are over 25 years still looking good and going strong ,because of

maintenance , whenever a tenant leaves our properties they usually leave a

fan or two , dirty , seized ,I clean them up ,oil them ,good as new , give them

to poor people in the area , with instructions on how to clean and maintain

them , but I suspect no notice taken , Thais are usually not good at maintaining

anything..........

Just a FYI, Lazada have bearing kits for the common fans, replace those dried out sintered-bronze bearings with pukka ball bearings.

 

Newer fans already have balls, you can buy just the bearings and re-use the rubber bits (check out your local bearings, sprockets and cogs shop).

 

Save some $$$ and save the planet!

We have a problem with fans not spinning, most times it is the bushes on the motor running dry, I take the front and back covers off exposing the motor I just put a drop or two of 2-sroke oil into the bushes, and most times it works, did one a few months ago, still working well.

You do realise that the brushes are designed to make electrical contact and not designed to be lubricate with oil, the graphite  is a dry lubricant. Adding oil to them will reduce their lifespan gum up the commutator and introduce possible shorting of segments.

 

The bearings needing lubricant is a possible problem.

 

I have quit a few brushed motors, several are decades old, none have ever had the brushes lubricated, several have had brushes replaced.

 

TLDR never oil brushes keep them clean and dry.

I think he said Bushes not Brushes

 

He's got bushes on his motor.

 

Yeah, bushes = those sintered-bronze bearings that dry out eventually.

I'd change the run capacitor too whilst the lid is off.

 

And use Singer sewing-machine oil from a syringe not WD40.

Absolutely, Thai guy round the corner from me who reconditions fans said WD40 dries out, sewing machine oil is the best.

Doesn't wonder me as WD40 is not a Lubricant, it's a penetrating oil.

With the help of Crossy, YouTube and Lazada, I have fixed many things, including fans for peanuts...😋

A Punjabi friend  I knew in the UK once told me that;

"The best way to keep your fan running well, is to make sure your punkah wallah is well fed".

While WD40 contains oils and solvents, it isn’t a designed as penetrating oil it is a WD40 contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal. 

 

a good penetrating oil will contain a very light oil and a solvent. Possibly the best is 50/50 ATF and acetone. The acetone will flash off quickly leaving the extremely light ATF

I said bushes, not  brushes, on each end of the motor shaft, are bushes, and as our resident sparky also said, those bushes dry out, Thais call them boots.

And yes, I did know you cannot oil brushes.
