It’s too bad they won’t go back to building ovens without windows, and these original self cleaning ovens were so well insulated. They’re far more energy efficient than any similar size range built today.
In the 70s, the Appliance manufacturers argued out of any regulations on energy usage by gas and electric ranges because they argued that there really wasn’t any difference, then they set about building gas and electric ovens over the last 30+ years that were more and more inefficient. today we have probably the lowest efficiency ovens ever sold in the world.
