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.

They charge u for it??

Mine did it for FOC. Panasonic and KDK.

But the KDK technician simply do it, they just screw tight the upper cover/canopy to the plaster ceiling to stop the fan from wobbling.

So now I just manually balance the KDK fans by jz using coins and cloth tape

thank you so much for this detail clarification, i will be doing all this next weekend.

if still no solution, i will go out and buy a new panasonic bayu 4 blades lah. ahahah

thank you so much
