Yesterday, my remote controller wouldn't turn on my fan or lights (on fan 52A4HR4L). Since I had two such fans, I reprogrammed the remote control dip switches and confirmed that the remote control was ok (it worked with the other fan, and the other fan's remote -- which I reprogrammed -- still wouldn't turn on the fan with the problem.
Rather than spend $20-$60 on another receiver (model UC7051R), I reprogrammed the receiver and remote for an entirely new dip-switch combination. This worked and solved the problem and saved me some $$$! I wonder how many of these receiver problems might be due to a single faulty or dirty dip switch?!!!
