Question about Bosch HBL 5056 Electric Double Oven
It is likely that the convection element is burned out and needs to be replaced. If all other functions are working then this is the place to start. Teh back panel inside of the oven can be removed by removing the 4 visible philips screws on it. The element should look smooth and round, if not then it needs to be replaced. Be sure to turn power off to the oven before replacing it. Remove the screws that fasten the element to the back wall and gently pull the element away from the wall an inch or so. the wires will be exposed and can be unclipped from the element do not let them fall inside of the back of the oven or you will have to remove the oven from the wall to get at the back panel. Install the new element in the reverse procedure. If the element looks good then it will have to be tested with a multimeter to verify that it is still good before proceeding to check the selector switch for burn marks.

After the oven is switched off, the after-run of the cooling fan is controlled by an electromechanical thermostat switch. The fan can switch back on, due to residual oven heat that accumulates within the oven's outer case and reactivates the cooling fan temperature switch. Considering yours is making buzzing sounds and activates on and off, the fan's thermal switch may have dirty contacts or just be defective and require replacement.
