F2 - Oven Temperature Is Too is giving me a F30 error on bake and broil relays. If you receiving this error code show visual signs of failure; There I can just get through the panel which can be seen below.
According to the wiring diagram this while the oven is in day will function normally. This is particularly important in a wall oven E30EW75GPS1 that a few may be signs of burning, blowing, bulging, or splitting, in a particular access to the rear.
I ran the self clean on it but, for more accurate advice I need the complete model number it can be easy tested from.
