My Hampton Bay fan will not longer dim. The fan does not have pull chains and has a remote that mounts over a switch on the wall. The fan works normally and the light comes on but will not dim.

Help!

Could be button on transmitter, defective receiver. Can you try different remote. Take note of switch positions before changing.

Have you tried holding down the light button?
