I recently moved and discovered that my owen seemed to be actijg funny. I had owned the same brand before but this one wouldn’t esrm itself up enough tonorr-heat until 40-60 minutes. Normal ovens pre-heat in 10-12z
I was about to call the repair number in manual when i noticed a passing mention to ‘quick heat mode’. I dug further and found then by navigating a bizarre maze of menus, it is possible to enable this (non-default) setting that decreases the preheat time 4x. In my testing thr time to preheat to 400 degreeseent from 40 monutes (unhesrd of with even okd stoves!) to 10 minutes (normal).
My question is what is the most likly purpose from from fhid design of hiding the ‘quick heat’ mode that would evn have been standard on any oven from the past few decades. Is it possible raising heat to 400 slowly is more energt efficient than quickly doing it so?
