said by SDR1 :The fan is made by Hampton Bay the "remote model # is UC7078T"
lots of them available on ebay, you will need to set the dip switches inside to match those in the fan
If ^ is correct in the model # ebay sells them for between $10 - $15!
I have to agree with the others you are going to need to open it up to see what info is in there, there must be some info on the motor or remote switch, etc!
