Oven door for Frigidaire Gallery PLEFM399DC does not close right

Hello Dana, thank you for your post!
From my understanding your Frigidaire oven is displaying an error code of "F8" and your keypad is not working properly. An "F8" error stands for runaway temperature (overheating). I would recommend performing a reset on your oven and you can do that by disconnecting the power cord for at least ten minutes.

If that does not help correct your issue then you could have a problem with your RTD (Resistance Temperature Detector) or the EOC (Electronic Oven Control). I would suggest having a professional technician out to perform a proper diagnosis and repair. I hope this information is helpful. -Matt

F15 Controller self check failed. Replace the EOC.
Here's the code explanation

Open the door and look at the hinges the connect the oven door to the oven body, on each side you will notice a piece that can be moved back and forth without moving the door, roll each side toward the oven body this should be the locked position, now try to close the door and you will notice the hinges lift up. At this time you need to pull up and push forward on the door and both hinges will come out.

Are you sure you gave us the right model number? My system doesn't show it and neither does the SearsPartsDirect web site. It shoulds like the switch is bad, but it could also be the thermostat if it is a thermatically controlled fan. The hardest thing in replacing a switch is getting to it and then putting everything back together correctly. Suggest taking digital photos on each step of disassemble process so that you can refer to it when you go to putting it back together.

Check you have put the trays in the oven correctly. Normally its because you haven't done so and they are preventing the door from closing fully.

Hi, i would check the pressure switch and its connection as well. either the switch is malfunctioning or the wires and connectors are corroded. simply replacing the wires or switch will fix this issue. the switch is usually located on the rim of the inside of the oven door. it will make contact with the oven door and as the oven door closes, the pressure switch is depressed inwards, thus, opening the circuit and cutting power to the light.

Please rate and god bless:)

Place a hammer handle between the door and the frame at the hinge location.
Carefully apply pressure on the door to push the door closed.
This will often re-set range door hinges.

These doors have springs to shut them. If you can figure out how to get to the springs usually you will see that one is either unhooked or unattached at one end. If broken on the end bend another hook into it and add a pice of wire long enough to make up the broken difference. 

OPEN THE DOOR COMPLETELY. IF IT GOES BEYOND HORIZONTAL, THE HINGES ARE BENT FROM EXCESS DOWNWARD FORCE. THEY WILL HAVE TO BE REPLACED.
CHECK THE DOOR HINGE SPRINGS TO MAKE SURE ONE OF THEM ISN'T BROKEN. IF YOU FIND ONE BROKEN, REPLACE IT.

The same thing with mine. I took apart the door today and found the hinges a little bent. I think it should be ok to bent them the opposite way a little with some mole grips......and then I must remember not to move the stove out for cleaning by the oven door handle again (oops).
Door comes off (unlock hinges and lift up). undo 4 screws on the bottom edge and then two on the inside of the door handle then it comes apart - beware as it's heavy. The hinges themselves come off with two screw each.
