I have a 1 yr old harbor breeze ceiling fan/light that works by remote only. The remote has quick working even though the red light still illuminates when pressing the buttons. I have replaced the battery.

When using the wall switch, the fan comes on but the lights do not which is likely the way the unit was being used when the remote stopped. I have checked the bulbs and they are fine. Thoughts?

First check that the dip switches still match. See:

But it's PROBABLY a bad receiver.
