Just to kind of add to what everyone else has said, I've done 2 or 3 now (can't remember) But I've always felt a little guilty about the extras I send. I have to remind myself that they chose my initial offer and everything I throw in extra is just for the love of beer. For me personally it...
Have you went through and double checked the settings on the ranco? I dont see what other than that it could be if the keezer worked before adding the controller.
I just pitch right on top of the foam, eventually it'll settle down and the yeast will reach the cider. You don't need to heat the juice either thats just making more work imo.
