This answer was rated:

Bosch HBN56M550B/03 Double Oven. Main Oven on fan oven selection keeps resetting to 160 degrees. Is this a simple part replacement? Convection oven selection does not appear to be affecte.
Hello, my name is George..

Check / Change the fan oven element

Kindly be patient whilst awaiting any responses from me as I'm not constantly available.

I have just discovered that the convection option resets as well. I cannot see how the element would do that, it looks more like a controller function to me. The temp doesn't drop, the display flashes and rests to the 160 default.

Then I suggest that you check the PTC Sensor connection at the main board Brian... The PTC Sensor itself could be defective, likewise the Mainboard itself.. But check the board connections first
