NO Way Not Even Close
Run Away Fast, you will be lucky if it ever even works properly, by the time they came out with Self-Cleaning ovens they had lots of problems.
Chambers even made the first SCWOs that WO sold under their name, as well as most Sears WOs for many years, they were a disaster to try to fix. Every once in a while we see one in a home still [ always where it was seldom if ever used LOL ] and someone wants to try and have it fixed, luckily for us there are about no parts still available any longer.
