How to repair the circuit board of Panasonic/KDK ceiling fans

In this video I will teach you how to diagnose and repair the circuit board for most Panasonic/KDK fans which uses more or less the same or similar circuit board design.
These Panasonic/KDK ceiling fan circuit boards fail pretty often especially when they are 5-10 years old but they can be repaired quite easily with minimal cost as long as you have basic knowledge on electronics and soldering. If you have an entire house running these fans you can save quite a lot of money repairing it and replacing the capacitor instead of replacing the entire board.
I never go into the removal of the board from the fan as it differs depending on fan design but mostly are simple screws from the top and/or bottom and then the board can be removed easily.

These repairs are so so important to reduce wastage and waste, without changing a whole unit of the PCB

Thank you for sharing this knowledge. I'm now on my way to fix mine as the fan failed to rotate. I had already bought a multimeter n it is now the time to test the knowledge that you had already taught us. Thank you.

Great and easy to understand explaination. Would better (or possible) if u could explain the malfunction of fan of each capacity. Anyway keep up the good work.

Thanks Jin. Very educational for a tender foot diy practitioner

Thanks for sharing your video. My KDK remote control ceiling fan is slow on the first and second-speed settings. At high speed, it works fine. I checked the 1.8uF capacitor it's showing 1.4uF and the 0.1uF capacitor is reading 0.07uF. Do you think both these capacitors need to be changed? Any pointers appreciated

tq

Yes thanks for your explanation. It makes me wonder why the capacitors are failing often,Is it due to inferior circuit design parameters or any other reason.I have three units and have changed capacitors a few times,

Electronics all have finite life.

The quality of the replacement parts the
are not great. Most of them are knock off brands. The original shizuki capacitor is of decent quality but unfortunately they cannot be bought on the market by end users. All the replacement "BM" brand or whatever is nowhere near same quality. For the red coloured ones, nothing much can be done, there isn't much choice. But for the black X2 capacitor in the middle can buy better quality ones from brands like Panasonic or Epcos from sites like element14 and they do last.

Wonderful...tq sir

2 alpha fans just died on me, 1 week apart. Nothing at all when power is applied. Im suspecting a failing power supply unit. Will diagnose when I have the time.

[@thyaaw]

Impressive!!! I have the same model, but my fan problem is it does not switch on at all. Fuse is good. Any advice? Thanks

[@alvinwilliamson9496]

Any idea what is the function of each capacitor? Issue with a single speed & timer not functioning.

[@nuvesv6933]

Terima Kasih Jin

[@alexpassive]

if the remote receiver not function, likely which capacitor goes faulty?

[@StevenFung]

The Aneng multimeter good? Price?

[@klunboxingstudio9889]

Hi bro how much are those capacitor?

[@jasonfzp]

Hi, I would like to ask how do I remove the circuit board from the fan. Thanks!

[@Nightstalker1993]

have to open the plastic cover from the top before you can remove the plastic cover on the bottom, for the panasonic fan that I have.

[@yee897]

Now j know where to send my broken fan😝🤣🤣

[@suranimalajinendrasinghe3291]

I chang every thing but still no power on

[@haryzXIII]

Is there anyway to check using an analogue multimeter?

[@Nightstalker1993]

You need specifically a multimeter that supports capacitor readout. Many cheap multimeters don't even have that feature.

[@haryzXIII]

@@Nightstalker1993 I thought as much T_T thanks for the reply. Something else I want to ask is that you mentioned that most ceiling fans uses the same circuit board and you could buy them for 40-80 bucks at shops. I need to test if it's the my board that's broken or the motor on a fan. Can I just swap the board to see which is the problem? Because I noticed the one on my circuit board is slightly different than the one on your video. Thanks again.

[@Nightstalker1993]

@@haryzXIII If you have multiple of the same ceiling fan at home, you can swap the boards around for troubleshooting. You can buy the Aneng multimeter, very good and cheap

[@haryzXIII]

@@Nightstalker1993 Well, damn. That's a very good idea. I wouldn't have thought of that lol. Thanks a bunch.
