and now return! Recirculation does not hold the heat which one you indicate; also the heat after the start is no longer to change, unless you turn the power off and start from scratch. This also applies to the time stamp that is not changing when the unit is running on time. Completely unsuitable since even after re-start for my needs, with greater heat, the dough in nearly twice the time was not nice but stuck to the form below; but whether it was dark brown. So no question of FAN.
