With the AKORN AutoKamado, if the heat sensor happens to fail (which it did for me a few months into using it) the ENTIRE grill is essentially bricked because the fan is locked from operating and this is the only way to get oxygen in from the bottom. If you could buy a replacement perhaps it may not be such a big issue but don't count on it. I have been in communication with Char-Griller for the past 94 days asking how and when I can buy a replacement and they will never provide a straight answer, so who knows if and when this part will be available for another person to review?
