[COLOR="Blue"]A piece of the resistance become so hot that melted and then touched the bottom of the oven.
When that happened there was a kind of small explosion and a very strong electric current noise, until the piece was totally melted and felt down on the bottom of the oven.[/COLOR]
Not sure I understand the above.
Did it sag and touch the oven floor and then spark or did just a small piece blow up and then the element dropped down and touched the floor.
How big of a piece?
Was it close to or part of one of the support feet?
Where on the element did it blow?

[COLOR="Blue"]I'm planning to change the bake element, however I wonder if there are some other possible problems.
For example, is it something that can happen or maybe there was a faulty thermostat that kept the resistor on too long ?[/COLOR]
Is possible or the relay contacts on the control board that control that element maybe welded together.
This you could check by unplugging the unit and checking across the contacts with a meter. Should be infinite ohms. If 0 ohms they are welded together. You will have to trace the wires as I do not have access to GE tech data so cannot tell you where to check.

[COLOR="Blue"]I was unable to find a thermostat for that oven so my fear is that I could end up to have the new bake element melted too.[/COLOR]
It does not use a thermostat. It uses an oven sensor and then the control board runs the elements.
Perhaps the following will help.

Note that often when this happens the voltage spike damages the control board.

Quick update.
The ohmmeter indicate infinite, so the relay seems not melted.
I'm placing the oven in safety and I'll see if turning on the oven I found 220V on the two wires of the bake element.
One of the two faston, that connect the wire to the bake element, was broken, probably melted as well.
Are normal faston or do I have to look for special ones ? Or I should try to replace the entire wire that from the relay goes to the element ?

The basic question is ... is it worth to repair it ? :)

Again, many thanks for any suggestion.

---------------------------
Update.
The electronic and relay seems working fine.
I can measure the 250V on the bake element wires, I can distinctly hear the relay going on and off. It remains the doubt about the temperature feedback but at this point is probably worth to try to change the bake element that I'll order in few minutes.
The other doubt is about the faston.
The original fastons are connected with an industrial machine, I can only crimp a new one hoping it will resist to the high temperatures.
Unless somebody can suggest me where to by a pre-crimped wire I guess I'll have to improvise.

Thanks

I see, but I was talking about fastons, like this one :

I have fastons around but what I have has a plastic cap over the crimp area, I'm sure it would melt. So I need to find a "all metal" faston hoping that the manual crimp will hold the high temperature. But I'm sure I will manage.
The wire is still in good condition.

Thank you so much for the help ! I ordered a new bake element and in a couple of days I'll try to fix the oven.
I'll post the final result.

Happy Thanksgiving !
