Who are you? We should meet. Hahaha

Anyway I'm also looking for ceiling fans and was searching DC motors and their effectiveness. Hahaha. I've searched everything and your'e the one that answers the Qs I have in my mind.

If I had a strong steady fan I may not need to use the AC. Right now I use an NSB fan in my room and it's squeaking. When it's on low mode it's super slow. when the installer first installed it, they blades were upside down and it was always a lousy fan in general.

Are fans easy to switch out on our own?

this sounds complicated....

also thoughts on 3 vs 5 blades?

I have a NSB fan that was installed awhile ago and the remote didn't work after awhile. Went to get a new remote from their warehouse. The installer installed it wrongly last time so it pulled wind up. Changed it and there was a better breeze but over the years it has become slower and slower at low speed. Only has 2 speeds. High and low. Low is REALLY slow. It's NSB Asta. It's now making a ticking sound and there's a bit of a hum.

I did ask to change the board or something but it'll cost some for their servicemen to come. About RM50 to check. RM35 for labour + spare parts cost.
That is already 1/2 price of a Deka Kronos F5DC (~RM200).

I'm thinking to install the Deka Kronos F5DC on my own. But seeing the Deka thread and the bad experiences I'm not sure. How bad can it be? As bad as my NSB?

I'm thinking of self-installing the ceiling fan but not sure if I'm brave enough to handle the wires connecting to my fan from ceiling. Are they all same for DC and AC?

I changed out the KDK K14y9 PCB on my own the other day. I know it's very basic to do but it felt like an accomplishment!

I changed out my ceiling fan!

I changed out my NSB Asta 56 with a Deka F5DC fan! The Asta only had 2 speeds and at low speed it was like it wasn't moving. Everything is made of metal.
The Asta was as heavy as a bowling ball and this F5DC is a lot lighter so it appears to be wobbling more than it should. It's silent though. It has a breezy sound. Not sure if I should worry about the wobble.
It took me many hours because I couldn't put my wires into the connecting board. I don't know why it didn't want to lock in. Everything else was quite easy. I'm not sure if I should install the balancing kit. I think the DC driver might cause it to be a lopsided on one side.

The Deka blades can't break that easily. They are actually quite sturdy from the feel of it. They aren't hollow inside. In my opinion, they are a little fat so they make wind sound. But it's safer. I feel those metal fan blades can slice you in half if it dropped on you.

At speed 1, it wobbles a little more. At speed 2, it's breezy and better. At speed 7, it's like a windy day and quite noisy. I'm not sure if I want to fix the wobble. It's not making any noise at all. Silent as a mouse except for the wind noise coming from the blades. When I was trying to get the darned wires into the wire board, I kept tilting it to check how to get the wires in. And it was so lightweight I could lift it off the hook.

The NSB Asta I had was AC and HEAVY. And maybe that's why the motor couldn't last because it was trying to move something too heavy. But heavy would mean it won't wobble so much? While the fan blades were plastic, they had these weighty metal covers. So the whole thing definitely weighed 3 times more than the Deka.

I had to buy these wire connectors because I couldn't use what they provided. I'm just really bad at wiring. There must be an easier way to get things to connect to one another. The NSB Asta, the electrician just intertwined the red/brown and black/blue wires together. But I think that's because it's AC. And when I was watching Youtube videos, I noticed the guy guy had a the blue and brown wire just connect to the DC driver. Their DC driver didn't have black and red wire.

Update: I think this is why AC PCB fan boards die fast because the fans are so heavy. Like my KDK I am pretty sure was quite weighty too. When i was trying to adjust it, it felt heavy.

Do DC ceiling fans run at constant speed? I was reading the box and it said that it's 38 watts. Is this constant at all speeds?

i think the reason for the wobble is because i overtightened the pulley part that's hanging on the hook. if that part is too rigid, the bottom part will wobble more.. as long as the cotter pin is in, it should be safe. i'm going to loose it later to see if it helps.

Do blades have numbers on them??

so i tried to adjust the blades, still wobbling
tried to adjust the pulley, still wobbling. now when i look at it, it's worse
and my brown and blue cable fell out of the connecting board because it's not secure. i might just buy another connecting board to use. it's hard when to get it secured when it's stuck to the pole.

can the wire not send enough electricity if not all the little wires are connecting? the way i connected is like... i'm afraid it'll fall apart again.

sigh. there's a ticking sound now.

OK fixed my fan. The safety cable was caught on the pulley.

Bought the connector clip. Then will climb up again and fix one more time.

My KDK where I changed the PCB, the buzzing sound is back at speed 2 and 3! Softly but it's there.

when i watch videos of overseas ppl and their ceiling fans, they don't have a box and the ceiling fan is close to the ceiling. What's the point of malaysians always saying the fan needs to be in a box?

the connector clips came yesterday but the wires didn't fit inside. So I stripped my blue and brown wires more and just looped them around the metal plate connectors I bought the other day. I feel much better now knowing it's more secure.

I had a lot of trouble getting the DC driver to sit nicely in the canopy holder this time. But now my fan, while still a little wobbly, is silent. I tried to balance with the kit but didn't know what i was doing and really don't have patience.

some times when i turn on the deka, it makes a grinding noise and the canopy vibrates for awhile before it starts up. What is happening here? Is it the DC driver that's actually making the canopy case vibrate

Is it easy to change the KDK regulator fan down rod? Right now, I think my downrod is too long so when the light is on and the fan is on, it causes this flicker like the fan is in the light's way

Thanks but these are official down rods.

Good day,

I changed the KDK K14Y9 board 3 months ago but the buzzing came back shortly after. Also changing the board kind of wrecked the remote contact or something. The other KDK is an old one but it is crooked and it's making lots of noise. I could just straighten it out but considering the power consumption...

I'm not an engineer but my guess is that the newer AC ceiling fans (e.g. got one KDK K15v0 recently), are rated 5 star energy but they consume 75w at max speeds.

I have the KDK K15v0 and it's good enough at speed 3 out of 5. It's also very big and I'm wondering if I can buy smaller fins and fit it out rather than changing the whole fan?. From the K12v0 range or something. Can I do that? Or the Panasonic equivalent? The reason is because it's cutting into my lights. I've removed the two light bulbs closest to the fan but now it's a waste.

Just like my Deka F5DC is good enough at speed 1 out of 5. Even speed 3 is enough. From what I've read DC can regulate electricity so that means at these low speeds it uses less electricity.

Compared to my NSB Asta last time with only high or low, low was practically non-existent. Heavy and I think this is why the fan motor couldn't sustain it and died years ago. It was just eating electricity while trying to move.

I removed the cover of my KDK ceiling fan (K14y9) and the humming at speed 2 and 3 is gone. So it must be this fan cover that is making the buzzing noise. What can I do to dampen the sound ?i tried to put in some sponge tape but I can't put back the cover...

It's a buzzing sound like. "hummmmmmmmmmmm" - I think it's the cover against the spinning fan blades.

I untightened the screws from the cover that is hiding the capacitor. So it doesn't touch the capacitor itself. Then I put the cover back and so far no sound at speed 2 and speed 3 has a very slight hum.

so when the cover touches the pcb it makes noise?

my deka fan is so lightweight that once in awhile it jitters when i turn it on and today it made a sort of whirring sound as it jittered. :/
