Ceiling fan

[w7_lee]

So you are not scared of dying ah?

 

No lah... if I know what I am doing and do the correct thing, I should not harm myself.

I have a question to consult the experts here. In Oct, my ceiling fan remote stop working. After troubleshooting, I concluded that the receiver was faulty. So I purchase a 3rd party remote and replace it (DIY). 

 

When I was dismantling the fan to access the original receiver, I tested the live wire using a test pen (like in the pic below). The fan switch is ON, so there is current reaching the cable connector. The bulb on the test pen light up, so I know which is the live wire. But when I touch the test pen on other metal parts of the fan (as indicated by the yellow arrow), the bulb in the test pen also lighted up although the brightness was lower. I touch it with my hands and could feel a little current. This fan was installed by the fan supplier 7 years ago and this is the first time I had to do anything to it.

 

After I put in the new receiver, I make the same check again (with test pen) and it still light up when I touch on the metal casing. It's been more than 3 months since & I have no issue.

 

I am the only person that could physically touch the fan, so I am not too concern it will kill others but just wondering if it is normal for the fan casing to have a voltage.

 

 

 

That means there is a leak of electricity from ur live wire to the fan.

 

Find the source of the leak and isolate it. Any stray wires/moisture?

Thanks for your suggestion.

 

The fan is in the living room, so there is no moisture except for those in the air. And I'm not even near the seaside.

At above the fan where the receiver is, there are no stray wires. I also put in new connectors. 

 

I'll have to check the compartment below the fan, the part where the start capacitor is located (I think).  If there are also no stray wires there, then does it mean the leak could be in the fan motor itself?

 

If I leave it as it is (with the leak there), what could happen in the longer term? TIA.

Is the neutral wire correctly installed ?

I'm thinking maybe it's broken somehow and the fan is running from live to earth, electrifying the casing.

Anyone have experience repairing Crestar ceiling fans? Mine is starting to slow down for L and M speeds. H speed still spins super fast and quiet, so I'm pretty sure it's just the capacitor also. I want to give it a shot (DIY), but how to access the PCB? Thanks

My elemak died recently.

 

So off to jb to get a kdk 4 blades fan and DIY.

 

One thing to take note for those DIY bros, the 4 blades are all labeled with weight on it, place two with the most similar weight on the opposite end so it is more balanced.

Are you using remote control? If so, then likely the remote receiver/transmitter needs replacement.

Yes, using remote control. At first the L speed started to slow down (almost no wind), so started to use M speed. And now M speed started to slow down. Cannot use H because super fast...

 

The problem is still I am not sure how to access the PCB. I tried to access from the LED light area from below and it only houses the LED and the driver.

With using a remote, probably the receiver is faulty. Your fan's pulls string should be set at the highest speed position, so it bypass the capacitors.The capacitors are in use only when no remote is installed. The PCB in the remote receiver is varying the voltage & current to change the fan speed.

 

The PCB in the receiver is normally not replaceable. You will need to get a new set (receiver and transmitter). I DIY mine some months back.

 

Attach picture shows where the receiver is (normally). It's the grey box.

 

I replace with an aftermarket type, bought from a lightning shop along Geylang. $45.

Thanks for the info and pictures! I'll take a look and see if the receiver is at the same spot.

Finally got time to install the new aftermarket remote + receiver. Not as difficult as I thought. Yes, it's located where yours are. Thanks again for the information. Working great again now! Saved me from throwing away a good working fan!

Malaysia is now selling the 48" KDK fan with LED for 800RM. Price in SG is more than 400 SGD!

I was looking for this about 6 mths back, they only got those 4/5 blades big type. This is their new addition. Singapores version U48fp, retail price $498.

This fan speed slowing has happened to3 of the 4 fans which were brand new 6 years ago.

One still working properly.

I've had a guy replace the 3 receiver boxes and this works as you say.

I'd like to do it myself next time just to save some dosh.

Check the capacitors inside the spoilt receiver?

Yup. It is new. I have the 60 inch one bought from Malaysia as well. Was looking to get a couple of 48 inch small ones but Malaysia didn't have it and I was not willing to pay more than 400 for a fan.

 

Will probably get my 2 fans soon.

Electronics stuff will fail with time, so be prepare that it will need replacement from time to time.

I guess that unless the motor itself has KO, otherwise, if we can do some DIY, we would not need to engage a handy man so often.

[Mcscot]

Bros ... sorry to ask for help ... I have a KDK ceiling fan which has this grinding noise with each rotation.

I am looking for someone to fix KDK fans? Any contacts?
