It’s an infra red heating element. So having it at the top is line of sight so the tray isn’t in the way and it spreads the heat out better too rather than directly below and above and the sides of the board heat up slower, was my thinking. I used to do lots of maintenance at a screen printing factory and they have quartz ceramic heating element arrays to flash dry the ink in the cloths in a similar way. It was also fun making it. I actually didn’t try the Kmart oven as is was I’ll leave that for someone else to try out.
Thanks for the vid!
I really wanted to know if the little flap / door in the back of the oven opened correctly when the exhaust fan kicked in?
Why would you need to move the bottom element to the top of the oven?
