Did it ever occur to you that a failure in a component in a machine specifically built to control fire might lead to uncontrolled fire in places you don’t want it?
It did. However, the beeping error only occurred long after the oven was used, and seemed to never happen while operating.
And given that we were aiming to have the oven turned off at/near the breaker most of the time, except when in active use (and therefore at least reasonably human-monitored), the risk seems acceptably low.
