Hi @jojovidallon
The oven is a Frigidaire model made for Kenmore.
As best that I can find out the technical data sheet for the model series 970-6784* which would have the wiring diagram etc is part # [https://www.searspartsdirect.com/product/2fpyti91bd-0022-628/id-316458450|316458450] (supplier example only)
Unfortunately I cannot find a free download online. You may have better luck.
Hopefully this is of some help.
