When I picked up my Wildcat, 1 of the functions on the remote did not work. The technician changed that function on the receiver to a different (spare) channel, reprogramed the remote to that channel, and everything continues to work just fine a year later. So, it is very possible you have a defective receiver with several bad/inoperative channels.
