Ovens have a chimney! WhatTF!??

Then
cool the kitchen at great expense!

I was flabbergasted! I was angry!
I was shoving pot scourers into that scam-ney as fast as I could!

I was happy to hear that my friend's electric bill had dropped even more than the temperature in her hot kitchen!

Ya that's why if you're cooking something in the oven and have optical smoke detectors near by they'll false alarm when you're cooking something, without even opening the oven door.
"Eco mod my oven"?

Works a treat on baked goods and chicken.

Oddly it only has an inch of fiberglass mat between the oven and control electrics and nothing between the transducers to control board

So there's no chimney venting hot air out the oven, but there is a fan to mix hotter air collected at the top with the cooler air lower down
and because you get more watts (heat) into whatever you are cooking if you thin the boundary layer there by moving air..??

I have no problem with that.
But any chimney that lets a significant amount of hot air convect out fast needs to be slowed down.
Does this fan blow down from above?

That's why I used to keep the door of the oven open for a while after using it, so any steam would easily escape instead of condensing inside.
