Not bad. Cheapest I bought was RM220.

Yuragi just sound quieter. It also has 5 speed which allow more adjustment. At full speed, there will be little difference in output I think.

The thing with Yuragi is that the plastic blades won't bend during installation and cleaning. Just have to look after those Bayu blades.

Change the capacitor inside the fan board. Very easy diy.

Last week took some time to dismantle my 7 years old Yuragi 4 blades because it has worn out bearings. Took me a while to figure out how to dismantle the whole thing. In the end, it was quite worthwhile because only cost me RM16 to replace 2 bearings. Don't even need to buy the 3 leg cramp that was shown previously by a fellow forumer. Going to do the same with my Bayu 5 fan.

I think Panasonic remote fan quality has been improved compared to last time.

Let me count the number of fans I had to maintained... for both mine and parents house.

2x new yuragi 5 blades (2015)
1x old yuragi 4 blades (2008)
3x old bayu 4 (2015)
3x old bayu 5 (2015)
2x new bayu 5 (2017)

So far, I find that the older version really problematic. Change capacitor almost once a year. The most problematic was the old Bayu5 and Yuragi 4 blades. 6months after capacitor change would still give a lot of sound and speed issue. I already took both of them out because too lazy to maintain. Before that, I even took the time to change the bearing which works like charm for few months before it also start to hum.

The most surprising is the 2x new bayu5. The new one has this rounded cover versus the old one with a sharper edge. I already used it for 2years+ and no issue at all. The old version would have start giving issue around 1.5years or so. It was so good that I even had 2 spares because it was cheap previously (bought for <RM200). I also had a Sharp 5 blades (bought out of curiosity and also mistaken for KDK for whatever reason) with reverse function which I had not had time to install to try.

Windless bayu4? Hmm... how much are you going to sell BTW?

Fans are so expensive nowadays... I still have 1 or 2 units of Bayu 5 bought few years ago... around RM220.

Actually Panasonic also change the board design and now more lasting. Previous model with flat cover, guarantee every year need to change capacitor. Even Nami not spared.

Later model with round cover had a much better board design and also they change the main 1.8J capacitor to a much beefier capacitor. After I got rid of all my old bayu 5 and replaced it with new Bayu 5, no capacitor problem for years. I still do keep some capacitor to maintain a couple of older bayu and nami fans in my parent's house.

Yuragi

I also had one. Ditched it already. My parent's house still have 2 5blades yuragi.

If you're using the old bayu, then you should change to the newer bayu. I got fed up replacing the capacitor and changed to the newer design with round cover. Haven't need to change the capacitor even after 4 years.


This is how the old bayu looks like.

There's basically 2 types of sound.

One is humming... Like mmmm, mmmm, mmmm which usually is a sign of failing capacitor and fan also spin slower.

Another is like scratching sound when the blades aren't screwed in tightly or properly. When turned on, one or more blades are rubbing against the bottom cover.

Most likely capacitor liao... is the biggest capacitor (1.8J) brown or black?

Yeah, this is most problematic model. I got tired of replacing the capacitors and moved it out to the balcony to dry my laundry. Also wont be bothered with the sound. I replaced it with a Sharp PJC176W which has been working like a charm for 3 or 4 years. A bit regret didnt bought extra when it was on sale for RM299 back then. The wind is definitely stronger than Bayu as well.

Right now the only few fans that I kept replacing capacitors are mostly at my parents house. Those old design Yuragi 5 blades, couples of old Bayu 4. Since I kept repairing them, they didnt see the need to replace them. Like you mentioned, sometimes I still get humming after replacing capacitors. I attributes them to the poor quality or even fake caps in the market. If the humming is very subtle, I would leave it. I would replaced another capacitor if its too loud even though I just soldered it.

I dont think so. I think the bad or failing capacitor make the motor hum. If you had a same type fan, you can take out the good board and try on this fan.

I think the cover somehow just echo the hum and make it more noticeable.

Corrected:

Old fan? Most likely capacitor failure. If those old 3 blades with speed dial on the wall., the capacitor is located at the fan's motor cover (not the one near the ceiling). You should be able to find a rectangular shaped capacitor after unscrew the cover and take it apart.

First of all, my memory is failing me thus apologize for sharing the wrong info on the location of the capacitor. My fan is a kdk.

1. No need to dismantle the fan from the ceiling.
2. There should be this cover on top of the fan motor (not the top cover which touch the ceiling to hide the life and neutral cable). Unscrew both screws and you should be able to take it apart. You will find a black capacitor.
3. Unscrew the capacitor or try to take a picture of the capacitor spec. There should be some writing on the sides which specified the capacitance. Then go find a replacement in those electrical repair shop or jalan pasar.
4. Screw it back on like how the original were connected. Certain model may require cutting and reconnecting cable. (Take some pictures before dismantle)

Remember to buy those wire cable connector for easier reconnection later. Some capacitor had an extended part to screw in to the fan but some don't.

Actually if those 3 blades with regulator, if no capacitor to try, can just bypass the capacitor (cut off the capacitor and connect both wires end together) and then spin the fan manually using a broom. If kept going means is capacitor rosak since it is the only thing you removed from the circuit. Capacitor is just there to start the fan spinning.

I think every brand also have good and bad.

Those Alkova by Alpha is decent... just a bit pricey

Actually you just need to change the capacitors. I have to say build quality on the motor is still top notch but they have resort to lower quality capacitor from China or even MY.

How to clean though?

Yuragi is kinda useless... fast and slow alternating, like wind... but if you are hot, you want the fan at full blast. I would say the usage is very case specific like some rare people I met that had difficulty being blown by wind directly.

If you ask me, I would rather have the yuragi works differently aka blowing fast for a minute then slow between 30-60seconds... right now they are alternating every few seconds. I find it rather useless because it took few seconds to ramp up the speed from slow to fast and then less than 3seconds already slow again.

There is a new type out there now that has a temp to control the fan speed automatically... I think this might be more useful...
