After replacing a light fixture the fan is not working but the lights do


Hello,

I just replaced an old light fixture with a new one and now my fan is not working. The light does turn on though.
I checked the wires for loose connections and that did not help.
I also assume that since the lights are working, it is not the light switch problem.

I cannot determine what brand the fan is, as it came with the house. The sticker says:
52" Ceiling fan c-52
AC 120V 60Hz 0.6 A 65 W
No 0252980 0801
Made in Taiwan 5AO 0008

The light fixture has a separate pull chain.
Inside the fan's "cable box" there is a pull chain switch and two black boxes, which I assume are capacitors?
The pull chain is not stuck.

Not sure what other information I can provide.
Any suggestions would be appreciated.

Ania

Is this a fan light combo unit? You only replaced light part of the unit?

Tell us all the wire connections in the box.

As joed asked, we need some additional information. How did you find a replacement light for a fan unit that you don't know the brand name?
Why did the lamp fixture have to be replaced?

After replacing a light fixture the fan is not working but the lights do


The fan previously had a light fixture, but from a sticker it seems that it came separately and was added to the fan later. The light and fan did both work before replacing the light fixture.
I just bought a simple light fixture at Lowes. The sales assistant did not mention it had to be compatible, so I never thought about it. I replaced it because the previous one was ugly. There was no problems with it.

The panel has the following wires coming out of the rod:

1. Black - going into the fan pull chain switch
2. White - connected with a cap to a white wire from the bulb socket
3. Blue - connected with a cap to a black wire from the bulb socket
4. Red - connected with a cap to another red wire, which in turn goes into a small black box #1 (capacitor?)
5. Light grey/whiteish wire - connected with a cap to two other wires of the same color; one goes to black box #2 (another capacitor?); the second goes into the direction switch
6. Pink - connected with a cap to two other pink wires - both go into the direction switch
7. Yellow - connected with a cap to two other yellow wires - both go into the direction switch

Moreover, a purple, brown and grey wires are connected to the speed switch and a black box #2 (another capacitor?).

I am attaching a diagram since it's a bit complicated (for me at least)

So, the only wires you touched when you change the lamp were the white and black?
Somehow the fan motor has to have a connection back to the white neutral..
The light grey / whitish wire may be it.

Correct. I only touched the black and white.
I did not change any of the remaining wire combinations, including the greyish/whiteish ones but I did make sure they were all tight, so I assume that is not an issue?

If all you touched were those two wires then something is missing. Put the old fixture back in and see what happens....
How is the fan motor connected into the circuit?

Perhaps the problem is at the top of the drop rod. You may have tugged enough on one of the wires to make it come apart at the top.
