I don't want to read "CO2 Emission Abatement in IGCC Power Plants by Semiclosed Cycles: Part A - With Oxygen Blown Combustion," so this is me posting.
That should be easy as long as it was installed correctly. There are usually trim pieces that snap or slide off around the sides, or you can access screws by opening the door, or both. Once you manage to get the screws out, which takes some creativity or those tiny angled screwdrivers sometimes, the oven should slide out. You can usually lift off the door to make it easier too. Then slide the sucker out and hopefully you have enough cord length in the back that you can set it on the floor on some cardboard or something and disconnect it, after you cut the breaker, of course.
I had to install my double ovens that my EE advisor gave me. Then I had to remove them because it toasted a thermal fuse and a transformer during self cleaning. Then I reinstalled it. Then I installed 2 new ovens for my EE advisor when his kitchen remodel was done. Then I had to remove, wire, and reinstall one that a stupid electrician pretended to hook up but didn't for someone else. I consider myself a pro now
.
EDIT: It looks like your oven is similar to mine except single. Whirlpool, right? There might also be screws towards the bottom corners fastening the trim pieces. I had to remove the oven door to get at those IIRC. It was a while ago, but all I need to do is go look at it to remember. I'll do that later when you are ready and when I shouldn't be working.
