LED ceiling fan repair

[D45]

5 year old ceiling fan not working as it should

Fan works fine however the light will not work

Power is going to the pull chain switch

There is a small transformer and the a round LED disk

I removed the disk and hooked up a 12v cordless drill battery to the terminals. Can't get it to turn on.

Any ideas on a replacement light?

Transformer also? What about the pull chain switch?

Thanks for any and all info

Seems silly to have to install a new $120 ceiling fan rather than to just repair it?

It's a driver (ballast). It's usually what goes bad. With it all wired up you could check for power coming in and going out of it.

That array it's 12v. 20-30something volts by looking at the driver.

Yea +1 on the led driver...

The spec says 21-36volt DC output of that red and black wire. The one where your pic 1/3 connector is connect to.
You can test the Diodes (LED) (the one on pic 1/3 with a continuity / diode checker function Individually, plenty of youtube video on that.. bigclive have few))
or a power supply capable of 36Vdc...


Saying that.. I would contact the manufacture for replacement... otherwise you'll be voiding warranty or any UL listings etc...

but for DIYer... LED driver at 36V are common on Ebay.. Those LED "can light" also have a disc like that I think... just not sure if it is the same size.


Just google for 36Vdc LED driver.... plenty.. just match the specs. 36V and the amp.

Meanwell is a good brand. But there are plenty of others.

Is there a fan repair shop in your area? I have found my local fan tech to be friendly and supportive.

So, you need to check for power coming out of the switch. Then for power coming out of the driver. Come back and tell us your results.

The important spec on the driver is that it is a CONSTANT CURRENT 360 ma driver that puts out the range of voltage. If you get a different ma driver, you will have serious problems.

Usually you will see those parts at big box stores, but with things the way they are may not be in stock.

I would check for voltage going in and coming out of the power supply as others have said. If you try to power the LED array directly with a power supply you may need to have some sort of current limiting on the supply or you may burn out the leds. You can put a resistor in series with the LEDs that will make it less sensitive to voltage. You can run the LEDs at much lower current for test - they just won't be as bright. If you have a variable voltage supply you could probably just ease up the voltage and limit how high you go.

Try lighting those LED's with 24V-DC. If they light look for a replacement power supply online.

I was thinking about trying to get the LED light disk to power up

What can I use? Jumper wires to/from what type of battery?

Got to be careful doing that. A constant voltage supply can fry the LEDs. They really need a constant current supply limited to 360ma

Contact the ceiling fan company. Ask them what to do. Do they have replacement parts? Five years is not too long ago, I'd think they carry parts still.

I thought it was Hampton Bay or maybe even Hunter

It says: "The 16-Watt dimmable LED light source will provide sufficient lighting as well as last up to 50,000 hours without replacement. Estimated life expectancy of the LED if run at 8 hours a day is 16 years"

Again, the fan is around 5 or 6 years old and is located in a spare bedroom, That is on maybe 3 hours a week

Looks like I have to call Home Depot to order replacement parts

Now, I guess I need to figure out what is needed:
-LED Driver
-LED Disk Lights
-Pull Chain Switch

I know I have power coming into the fan, because the motor will turn on an power the blades

The non-contact tester also shows I have power coming in to the lighting area

Can I bypass the pull chain switch somehow?

 

[D45]

I removed the pull cord switch for the LED light and cut the wires, basically bypassing the switch to rule it out

Wired directly into the driver ballast, the LED light turns on

Time to shop on Amazon for a replacement pull cord switch

The switch is marked:

Zing Ear
E89885
3A250VAC
6A125AC
6A125VL

you might consider getting a VOM and have someone show you how to easily use it. Would have eliminated the need to cut the switch out to test it.

Thanks!

Now I need to find a 2 wire, 3 speed switch........
