About 1 month ago our we turned our home oven (Whirlpool model RBS305PDS12) on to 400 and it preheated and then I open door and put food in to cook. I closed door and the oven door locked and started a self cleaning. I tried turning off (which did not work) so I went to circuit breaker and turned it off and let it cool down. Once cool, I tried opening door (without turning power back on) and was not able to. I turned power, at breaker panel, on and got an error message (I don’t remember maybe E3 F1) and I was able to get door open by using a coat hanger.
What part(s) should I order?
