I have a Bosch single built in oven model number HBL45 with convection. Recently the Convection Bake function stopped working. The fan runs but there is no heat. From reading the manual it sounds like Convection Bake uses its own heating element in the back near the fan, so I'm guessing there is a problem with that element. All other oven functions work fine.

Is there anything I can do to fix this or do I need to call for service? Thanks!

If you are willing to take the element out, check it for continuity. If none, replace it. Not a hard or expensive job to do. Saftery first--Unplug unit first before attemoting any repairs!!
