Oven in the wall
I don't know what years A/S installed the split oven/range with the oven in the bedroom wall but I had the same problem as many others, the oven thermostat quit, oven would heat but not regulate. Repair was costly for a seldom used appliance so I removed the oven, turned the space into a cabinet with shelvs for microwave and toaster oven. I used mahognay for the door frame and had beveled mirrors made to fit the door frame and a solid mirrored section to match the curved wall.
I tried to put a url to the pictures but it didn't work so I will post the pic here.
