I had this oven repaired 2 years ago after I tried to clean it using the self-cleaning buttons. The repair man checked it and said when it self-cleans sometimes it gets so hot it makes the oven shut down. He put in parts and charged $400.

Last week I tired to clean it again and again it shut down with an F4 message flashing and beeping. I hit cancel and it stopped flashing but the oven will not work at all.

Is there a way I can open it up and check if the wiring has come loose? There is a control panel in front where the knobs are but I need to know how to open it. I don't have a schematic on how to open the panel. Any suggestions?

PS The clock and timer both work fine.
