I am having some issues with me control panel on my pro series PBV4PS2 vertical smoker. When I turn on my smoker, it goes directly to "5" setting (for smoke) and after it gets to 130 degrees, I cannot get the control knob to change the temp after I push knob and it starts blinking. Stays on "5/S" the entire time. I can change the temp on my SmokeIT app but then when I press the knob, it immediately reverts back to "5/S". While this isn't a problem when I have the app with me and all of that is connected, it would be a problem if I don't have the app to change it. Has anyone else had this issues? Any fixes?
