My Casablanca ceiling fan model p4m55h has worked fine for about 2 years. Now the remote will not operate fan or light. I have checked light switch wiring (all ok) replaced battery in remote, and checked light bulb. Could the problem be in the transmitter in the fan housing? H E L P ! ! ! Thanks

Hi, my name is Shaun. Welcome to FixYa. I have been an electrician for 6 years, and I have to say that your troubleshooting skills are impressive. Looks like you have covered all the bases. So, to answwer your question, the problem is most likely, yes, your reciever in the fan, unless the transmitter has been dropped or damaged in some way. Recievers rely on transitors to close the higher voltage circuits to turn on the lights and fan, and these tend to burn out occasionally. I believe you can buy wireless kits from Home Depot or Lowes that include both transmitter and reciever. In the meantime, you can rewire your fan and light to operate from the switch if you have pullchains or seperate switches for light/fan. If you do and you would like me to walk you through this process, reply to this answer. Hope this helps out. Have a good one!
