Eric for Model Number HBN5450UC/07 Hello: The Bosch wall oven is pulling an E115 code and it is likely the relay on the control board causing the problem. Is that correct? Or should I test the sensor first? The site says that the board 12022212 replaces the one in my oven 00659614. Is this a really improved design as I have already replaced this board 5 years ago? Are the components any better designed in this version of the board. Thanks Eric
