All of my remote controls have been tested and are known to be working. If they don't work, they don't get listed! Please make sure you order the correct remote. If you need help in determining which remote works with your equipment, please contact me and I will try to guide you. Returns are accepted ONLY if I ship something other than what you have ordered! Otherwise, there are no returns and no refunds. Used remotes are sold as-is as described. They have all been tested and are working when shipped. Remotes are sold with no guarantee or warranty beyond the fact that it works when you get it! Buyer is responsible for ordering the correct remote for their equipment. Any agree returns are at the buyers expense unless I have shipped an item in error. Thank you for understanding. IrvR.
