If the fan won't turn off, it means that the oven thinks the inner cavity is still too warm. This is either a bad oven sensor or a bad display relay control board. 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 you need to replace your relay board. Since you're already replaced the sensor.
