I have a Harbor Breeze remote fan that is appox 5 years old. It works good, however recently I have been unable to reverse the blade rotation. The remote works for all of functions (hi, med, low and light). The only issue is the reverse, any suggestions on what might be the problem? When I press the reverse button the red light on the remote lights up.
Thanks

Receiver is starting to fail. Spin the blades in the desired direction, and cycle the fan off and on until it starts operating in that direction.
