F1-1 and F3-1 error code

Very easy to repair, but you have to be able to pull your stove out. Two screws in the oven and then remove part of back cover of oven and one plug from there. Simple to do, but did not fix our problem. We are waiting repair now from service company as it looks like it needs a control panel. Worth trying yourself to fix the problem. Inexpensive part and easy to install. Also be sure to turn power off your oven to reset the control panel as this may fix the problem - try this first and also after installing new part - like rebooting a computer...
