Hi, my name is ***** ***** I look forward to helping you! There is a thermal fuse that has likely opened. Usually, that is caused by the cooling fan not running or not running fast enough. The fuse is usually mounted on the back of the oven, behind the access panel. Some are mounted on the top, under the access panel. May I please have your model number so I am able to provide you with accurate, model specific information?

Hi, I have just got back from holiday so in response to your question so that you can assist with my original query it is a bosch pyrolytic oven model number hbn730560B/05. thank you very much.
Expert:  Kelly replied 2 years ago.
Thank you! On that model, the Er15 means that the control thinks the oven is too hot and has locked for safety. Obviously, that is not the case if it is cool and the error still exists. So, that means either the oven temperature sensor has failed and is sending erroneous information to the oven controller or the controller is failing to interpret the signal from the sensor correctly. The oven sensor is much more likely to be at fault. Do you have a meter you can test the resistance of the sensor with?
Customer: replied 2 years ago.
No. to be honest i dont even really understand the question.
Expert:  Kelly replied 2 years ago.
Okay, well I would replace the oven sensor or call for service. One of the components has failed, that is for certain. Either the control module or the sensor will need to be replaced.
Customer: replied 2 years ago.
I have replaced the sensor at oven error code 15 is still there
Expert:  Kelly replied 2 years ago.
So the issue has to be with the control or the wiring between the sensor or the control.
