How do I replace the thermostat on an Avanti 24" stainless steel electric range

SOURCE: Preheat taking long time

If your oven has the hidden bake element then it is probably working properly. A standard oven with an exposed bake element will usually take about 12-15 minutes to preheat. The hidden element models take a little longer but they usually heat a little more evenly.
Post back if you have any more questions.

It is very common for elements to "catch fire" when they fail. It is really electical arching. But to answer your question you shouldnt be concerned if it ever happens to the bottom element immediatly kill the breaker it will stop instantly. dont use a fire extinguisher as it wont stop the arching. And most ovens do use the upper broil element for baking for very short intervals like 10secs on every minute or so to brown the top of product. Some models (especially older builder line ) do not

glass cleaner WITH ammonia, and a small toothbrush works well. mop up with an old washcloth, rinsing often. for pieces which have gummy residue, and which can be removed to the sink for soap and water finsing afterwards, try GooGone.

It sound like something shorcircuited and put WAAAAY more current through your oven than it can handle.
You could test the circuitbreaker's circuit by pluging something else in that circuit (a 2kw appliance would be an appropriate test).

It's hard to say for sure but with a fault like that if it wasn't from the oven itself your circuit board should show a visible sign of overcurrent.

I would suggest trying to get something out of the Frigidaire, talking to the retailer if he can do anything and if no one gives contact a consumer reports journal. They love dirt like this.

Frankly, this fault, if it is oven related is dangerous and all appliances should be 'intrinsically safe.'

Good luck.

SOURCE: Stainless Steel Range Tops.

The only way to clean it is with steel wool. I use 2 different grades, but finish with a fine grit-0000. You still can't get it completely clean, no matter what you do. Forget it looking new. It's not real stainless steel if it's model FEF455BBA. I won't EVER buy this sort of top again either. I have had numerous problems with it, including since it conducts heat and doesn't shield wiring from the heat generated by the eyes, it is constantly melting out the plug-in elements for the eyes. I am surprised it hasn't been recalled. I am surprised more people haven't had fires!
