I have two fans in my living room, separated by a chandelier. There's basically twelve feet between them. Both use remotes to control them and are on the same frequency as far as I can tell. Both have lights on them, and the remote controls the fan rotation and speed fine however I have to be standing literally underneath one of the fans to turn the light on. Now I think it's the receiver because I have a third party remote that I use to control the fans, and the same thing happens. I can turn on the fans but the lights are sketchy. Is there an issue with the receiver or something? These are rf remotes as I don't see any sort of ir on them.

 

On many of the remote receivers there is a short stub of wire. That's the antenna.
If you can bring that wire out under the canopy your range can be extended.

 

Ok. How much wire? Is it possible that it's the receiver? Would it be better to replace it? The receiver is at least ten years old. I all because the fan turns on, it's the light that's in the fan that's sketchy.

 

The range should be the same for the lights or the fan.
If your receiver has the antenna wire it will be several inches long.

You can always replace the receiver but there is no guarantee that the new one will work better.

 

Ok. I'm just concerned that the something wrong with the receiver since the fan party works but the light doesn't.

 

There is one common receiver that has two halves.
One half controls the fan. The other half controls the lights.
It is possible that one half of the receiver is bad.
Did you check the bulbs.

 

Yes the bulbs seem to turn on fine. The one only seems to turn on if I stand directly below the fan light and point the remote up and at the fan.

 

A little confusion here.
You mentioned a problem with the lights several times and then said the lights are ok.

 

Sorry, I meant the bulbs seem ok. Here's a video I took off the behavior, I'm pressing the light button once on the remote each time.
Fan lights

 

Does the video help?
Also, how do I stop buzzing?

 

Two fans on the same frequency (code)..... that's just asking for trouble. The problem is just what you are seeing. If both fans don't get the command from the remote.... they will get out of sync. That means you need to shield the remote and move around the room to get one to respond and not the other one.

You mentioned a receive problem with one fan. Those fans look like they have integral receivers. In other words the receiver is in the motor section and cannot be replaced.

 

I was able to take the canopy off, and I can see the receiver and antenna under there. I exposed the antenna, as you suggested. No luck. I think I may have made it worse, because now the fan makes a buzzing sound. That's for another post though. I'm thinking about replacing the receivers, with newer ones, that can handle dimming LED bulbs. Do you have suggestions? I was looking at Amazon and I see many, many remotes but not one that does dimming on LED lights.

 

I can't recall any universal remotes that can operate LED bulbs. That will take some researching.
I didn't hear any buzzing in your video and taking down the canopy shouldn't cause that either.
Pretty surprising lowering the canopy didn't allow the receiver to pick up better.

 

I agree. What's strange is the fans turn on together. The lights don't.
