Yes, but the remote operates on the switch that turns the lights on and off. Lutron has this kind of technology and it is really cool. I have it all over my house and I don't even have to go room by room turning lights off; I just push a button from my bedroom. Along with a single remote that can be used with each switch in your house, you can program a house remote that controls the lights and ambiance of every room.

It is wired so that you control the light with the remote. You cannot have it both ways. You either control it with the wall switch or the remote. Once you kill the power to the receiver by turning off power at the wall switch, you are only applying power to the receiver when you turn power back on. You are not supplying power to the light. You then must turn on the light with the remote. This is the purpose of a remote fan/light control. You could rewire it to control the light with the switch and only control the fan with the remote if you wish, but as you have it now, it is working correctly.

The remote is a Hampton Bay remote that should dim the light and fan on and off. I replaced the battery and do not have a red light when I press the button. Light and fan does not turn off with remote.

Check your remote control using a camera or cellphone camera as your eyes. Point the remote control transmitter to the camera and "on " the remote control. A light should emit in the remote control. If no light is present then the remote is not transmitting or defective.But if the remote emits light then the indoor receiver is defective. And try also the reset or rst button if available in your remote control, just press it and try the remote.

First you have confirm what really the defects is, is it the remote control or the control board.

HOW TO CHECK THE DEFECTIVE REMOTE CONTROL:

If the lights emits that means your remote control is good, if not means the remote control is defective. If the remote emits light it means that the receiver at the control board in the indoor unit is defective.
