I recently went out on a call to fix a Frigidaire double oven that would not bake. M# FPET3085KF. I figured it was the bake element. There were no error codes, the broil element worked. Took the oven all apart to check the bake element, which can be checked from the front only to find out the bake element had continuity through it. I did not have current going to the element. Everything on the board and key pad checked out fine, but did not have a reading through the bake element from the board. I then pulled the double oven out of the wall to find out the resetable thermostat had popped. There is a red button on the thermostat that needs pushed back in. The customer had recently put the unit into self clean. I guess being a built in unit caused the heat to get too high and popped that thermostat.
This can be checked from the board.
The bad thing is: the only way to reset this thermostat is to pull the oven out of the wall and take the back off to get to the thermostat.
I am posting this to let others know to check this before ordering a very expensive bake element.
I hope this helps some others.
