If your oven starts to get too hot, a low-level software process will tell the June Oven to disengage your cooking process by ending the cooking session immediately. June will then run the convection fans on a high setting to cool the interior down without assistance.
June Ovens have a mechanical thermal cut-off switch — it’s the first thing current passes through before going anywhere else in the oven. This thermal cut-off switch can be activated when the oven gets too hot and without the aid of software. When activated, the oven will shut off completely. The cut-off point occurs well before there would be safety concerns, or physical damage to the oven.
