My MES control panel is acting weird. It will beep about 5 times, and looks like "FAAF" on the screen. When I push the temp button, it just beeps. I looked in the manual, and it says if there is an error with the control panel to unplug it for 10 seconds and plug it back in to reset the panel. I did, no luck. I called MES customer service on Monday and was asked if I left it outside. I told her it's a smoker, of course I leave it outside, but it's covered. She then asked if I brought the control panel in when it's cold. I told her no, I don't take the control panel off and bring it in when it's cold. She said I needed to take it off, bring it inside to get it to room temperature, then plug it back up and see what happens. She said I needed to unplug the control panel, not the power cord. I'm going to take it off tomorrow and bring it inside, then plug it back up and see what happens. Ideas?
