When Hoshizaki first came out with the flapper type bin controls i got several calls where machines would not run when started up. The shipping tape was never taken off to let the flapper hang down. The factory paid me under warranty. But now with things as tight as they are they probably wouldnt since it is really an installation issue.
had to retro mini new bin control from mechanical to thermostatic ,dont forget the bin braket.the extension.
