Ceiling fan with lights on the remote works and have multiple fans in the house with the same remote but when u turn the lights off to this fan the fan wont run

Did you set the remote to CFL mode?

The light on the remote is a battery light. First mistake was buying a store brand fan which are mostly low-end parts. Try adding a different remote w/receiver.

I had this exact problem. I bought two Home Decorator fans from Home Depot and installed them in separate rooms in my house. They have LED lights. I know for a fact that I wired them right because the model fan in Home Depot fan was wired the same and my remote worked perfectly with that fan. Both fans at my house had the same issue of the light not turning all the way off but dimming worked and fan speeds worked. LONG story short, I had another fan in the Master Bedroom that was turned on. When I turned the power to that fan off (wall switch toggled to off), both of the new fans worked!!! Now I need to figure out how to wire the Master bedroom fan correctly (9 wires in one box) but at least I know what the issue was!

Three suggestions (maybe not viable solutions):
1. Consider creating ceiling fan "groups". A group is a set of fans that is controlled by one remote.
Group: All (or some) in all vaulted ceilings.
Group: All hallways
Group: Outdoor celing fans
2.
Power OFF ceiling fans at the wall switch that are not used often. Those can have duplicate codes.
3.
If the remote controls are iR (infrared) rather than RF (Radio frequency), then the ceiling fans that are farthest apart or have more solid walls in between, can have the same codes and not be affected by the "wrong" remote.

With mine, I turn off the full power and back on and it starts beeping and and press any button on the remote and it finds it and does a couple confirmation beeps.

It's most likely the receiver for the remote (transmitter) -- it's located under the cover at the top of the fan -- will need replacing.

I would begin by testing each bulb in a different socket somewhere in the house.

Ceiling fans with wireless remote controls have an electronic receiver installed in the fan, which controls the light, dimming, and fan speed. Sometimes the receiver goes bad and needs to be replaced. If you have had any power outages or power surges, they may have fried the receiver. I've noticed that my ceiling fan light turns on when the power is restored after a power outage. Now, whenever my power goes out, I shut off the light switch that powers my ceiling fan so It doesn't experience a surge to to the controller when the power comes back on. I've purchased new receivers on eBay and Amazon to replace my blown remotes and receivers.
