The Anderic UC7301R-03 receiver has a higher capacitor value and can run the fan speeds at a higher rate than the Anderic UC7301R-01 model. Please check your original receiver to see if the receiver reads "-01" or "-03" and purchase the correct receiver.
If you are replacing this for your Altura 68" Ceiling fan then you may not be able to use your original remote. Your remote needs to be the UC7222T or RR7222T. If you have UC7222T434/CHQ7222T434 (434 frequency) then you will need to buy the new remote RR7222T. WE SELL A KIT WITH RECEIVER AND REMOTE. "UC7301R/RR7222T-KIT for MR77A Altura 68in"
