I have a remote on my ceiling fan. Until last night it worked fine. It cuts the lites on and off. I noticed this morning that the lites come on , but are dim. The fan works fine. What could be the problem?

Maybe the remote has a built-in dimmer function. You might press and hold the light button and see if the lights brighten up. Release when they are fully bright.

Just a guess, but it might help!
