Hello, and thank you for using this service. I'll be helping you with your problem today.

F7 means that your oven isn't heating properly. First you'd want to test the temperature sensor. You can't test the board but you can test the sensor. Open the door and remove the 3-4" long thin metal rod attached to the back wall. There are 2 screws holding the sensor on that you can remove and then pull the sensor forward until you can disconnect it. WIth a multimeter, check the resistance of the sensor at room temperature and it should be about 1080 ohms. If it's not, replace the sensor, otherwise make sure the oven is getting 220 volts from your house to the terminal block on the back of the oven and if that checks good, test continuity through the bake element. If the element has continuity, your main control board is just faulty and would need to be replaced.
