I would think it is a control problem... but also check the door switch..
Check the Basics first!!! Read the Manual !!!Buy the tech a Beer!!!

Hello Krazytech,I was not sure what the problem was,I was just asking to see anybody had such incidents before.The symptom is strange.I may need to pass it on to a Bosch repairman.Thanks for the advice.I will wait for more replies before going back to that job.

heat with door open?  no heat with door closed?  sounds like the opposite of what it should be doing. 

  I would think control issue as well.  especially since the self clean works. 

   an obvious temporary fix for the customer would be to disable the door switch until the new control comes in.  I am curious on this one as well.

I suggested to the landlord to hire the Bosch repairman to tackle this job.Will report back what the Bosch man found out.

I talked to the Bosch repairman who fixed the said wall oven.He said this same break-down happens quite often so he knew the problem right away.One time he asked the Bosch experts about this problem.They told him it was the circuitry inside the selector switch defective.There was no obvious spark or  burnt marks.It would have taken several hours of tedious testing to find this solution.So there it is,a selector switch causing this misleading problem.
