Here is how I converted an old stove to a Powder Coating Oven.

I had that stove now sitting for some time. First disassembly and cleaning, prep. for Paint.



I'm using engine enamel paint just to be on the safe side. The main parts will be red.



Door and the front section will be silver.



Adding a little bit of details just for fun.



Two of the heating plates, will be deleted, to keep it simple. Too many switches and cables.



Now I have only 2 connectors left for the heating plates



I tested the 2 elements which I left, and they all work.



No worries, it's not bend. Just the picture.



Now I got 2 holes with the heating plates removed. What can I do with the holes.



I had a nice piece of table top left over from the desk I converted to a drawer only piece. This makes a nice cover when the oven is not in use.



After the first time I put some pieces in the oven, I noticed that the temperature control of the coating oven was really bad. I had to watch it all the time.

So I did some enhancements. Added a PID digital controller, a better thermocouple, and Solid state relay.



Now the oven keeps the temperature within 2 Deg F.



I had to modify the back panel to make some space for the PID. I just cut out a piece of the panel, and riveted in another piece of galvanized sheet metal.



This is how I wired the PID, Solid state Relay, and the on/off switch for the controller. I removed the original TC and disabled the baking switch, and kept the broil switch as on/off switch for the heating element.

Please note that this is how I wired it, do your own wiring at your own risk.
