How to prevent fans thermal fuse from blowing up 

You're welcome ... And thanks for your visit 😀

like videos I am from nepal

Thanks for watching!

I try to make my video as a guide, so I have to make it as clear as possible, step by step. For those who wish to repair their own fans at home and the procedure were always starts from (A to Z) not the other way around and and thanks for your nice comments and thanks again for your visit

mikel77 that's were the main idea .. thanks for your visit

better is he should have put a fuse housing on the 1.5A for easier replacement should it blows next time

Yes, you are right

Thanks to your constructive comments ... and thanks again for your visit..

no need ...

That's fuse were usually 13Amp ... Very rare that's fuse will blown off

Winston Clarke the fast blow fuse were better than the fuse which I used ... Choose the smaller amp ... Let's say the thermal fuse were 2A 130c ... The extra fuse would be 1A ...

MC Liu yes .. your are correct at something there, but base on logic ,the thermal fuse were 2A 130c and it's will blow either when the amp in the coil over 2A or the temperature reached 130c .. which came first ? The coil will never heat up to 130c even if you run the fan for 24hrs full speed as long as the fan blades were spinning normally without getting stuck somewhere and the air circulation at the fan motor were normal without getting block by build-up dust ... And only when the fan blades were abnormal .. the load in the coil will rose and the amp will surely getting higher and do remember ,the add-on fuse were only 1.5A and if I have a 1A fuse with me, I will surely use the smaller one ... Anyway thanks for your opinions and thanks again for dropping by ...

This info is so correct since one fuse blows because of an increase in temp from the coil over heating and the other is current drawn or current supplied.

@@KluangmanCooleck Don't think the Chinese really give H-type insulation in these fans. With a partial short the windings heat up even to 130+/-5 celsius and the fan rotating (I measured with a K-type thermocouple without cowling). I suspect that even 110-120 centigrade will cause melting/short in the laquer insulation in these fans. So the thermal switch disconnects, but some damage to the windings is already done. I would recommend a 100 centigrade switch replacement. And replacing the sintered bronze sleeves by ball bearings (like 6300zz or 6300rs for 10mm shafts) in fans with steel frames (not the rubbish aluminum like in this video).

Broken wire or faulty speed selector

Winston Clarke yes ... Please use the same rate ... or you can use a smaller one but don't use thermal fuse with higher rate than original ... Or you can use circuit cut off thermal fuse

Thank You.

Resistor ? Did your fan using resistor to control the speed...like cycling fans for example..

No, I meant using a spare resistor to bleed off any residual charge in the run capacitor so as to not get a shock from it, even out of circuit.

if you a very sensitive to electricity kind of person,you just need to short circuit between L and N at the power plug with speed selector turn on before dismantling the fans for precaution but the residual charge in the capacitor were too small and its will fade away less than a minute after power off

Awesome. Thanks for your advice.

And thank you for your visit ..have a nice day

NO .. but sometimes they have load breaker

Can I replace the thermal fuse by normal glass fuse ? I can afford good holder and location for it. But will that work? Does the regular fuse blow up because of heat?

Judging from how black the tip is, I would say it's probably some generic cheap iron. Radioshack sold an iron similar to that which had junky nickel plated copper tips that would turn black and burn the nickel off. I would recommend something like a 40W Weller or Hakko soldering station. They're $50-$160, but well worth it, you'll spend more buying cheap replacement irons with tips that burn up.

GGigabiteM Got it, thanks for the recommendation :)

SK Mainuddin when the bushes wear out , there are nothing that we can do , some said replace the bushes .. but it seem impossible to find that kind of bushes anywhere ... If you have another spoil fan which damaged coil .. try to re-use the motor housing ..

I can send you a couple or two of these sleeve bushings, but you have to immerse them every year into a heated to 100 centigrade (boiling water bath) motor oil., Simple wetting of the outside of the bushings by oil (even SAE 5) will not let in enough oil to lubricate for a year of work (like 1000 hours of rotation).

Yes you can ... A to A .. B to B ....

Kluangman Cooleck tq.. will try it

In DIY ... Trials and errors ... Are our best teacher... Good luck... Safety First ...

Kluangman Cooleck .. do u hv a fb acct or watsapp? need to show u pics& get advise.. tq

s.k a very good question .... If you have the same size fuse which can fit into the power plug .. go ahead ... But normally that's fuse were rarely blown off ... and to search for that's fuse with smaller amp rate .... Emmmmm it quite difficult ....

and maybe you have to search every electrical store at your hometown just to find one

so the fuse you installed are not the same physical size compared to the ones in the plug?

s.k yes ...

thank you, that was very helpful

None .. normally closed or NC

@@KluangmanCooleck what is NC means

@@pancakeyummy4070 normally close

@@KluangmanCooleck ok thank u 😊

you are welcome ... and thanks for your visit

@@KluangmanCooleck sir i just to know where i connect the extra fuse?.

@@joelmontealegre.banaco1224 minutes 25 in this video ...

@@KluangmanCooleck thank you. Sir

If you have a fuse, which is the same size with the fuse in the power plug ... Just replace the smaller amp fuse there .... Such as 1A or 1.5A ... Because the thermal fuse inside the coil are 2A ..

It needs to be placed near the area that gets hot in order to prevent a fire from happening. If I'm not wrong.

read the video Description please .. and thank you for your concern

Yes .. it can run without thermal fuse

@@KluangmanCooleck if no thermal fuse the motor will be destroy?

@@joelmontealegre.banaco1224 no .. install additional 1 or 1.5 amp .. fuse as a circuit breaker ..

@Kluangman Cooleck The purpose of a thermal fuse is to open and cut off power if temperatures get high too high. It is bad advice to say it is OK to take out the thermal fuse. If your fan didn’t have a thermal fuse, your house may have burned down. It is this important.
