I have a Hunter ceiling fan with four lights. Then without anything unusual happening the fan and lights simultaneously stopped working. I operate the unit using a wall switch. When I turn the switch to "on" I can hear the unit beep so I know that power is going to it, but when I press the fan or light switches nothing happens. I took a look and all of the connections in the wire nuts seem to be OK both in the wall switch and in the ceiling fan. Any thoughts are appreciated. Thank you.
