I've always been suspicious of self-cleaning ovens and thought they were a danger. In order to clean, they must heat to very high temperatures and incinerate the stuff stuck to the oven surfaces. The heat in and around the oven during the cleaning cycle is evident and of concern. Also, the cabinet surrounding the oven must get hot, as well.
Are there many fires or electrical failures associated with electric self-cleaning ovens?
I have cleaned my oven only once on 4 years because of the concern. Are the ovens really up to the task of tolerating the high temperatures?
Also, any hints as to how to reduce cleaning frequency? Is putting aluminum foil in the bottom under the heating element a good idea? My wife wants her oven clean all the time but, I'm reluctant to use the cleaning feature regularly.
Do I need a shrink or some therapy or are my fears well founded?
