De Dietrich F 4827 has ER1 error message on top oven which wont work. Bottom oven ok what is the problem

Just had the same problem on mine. I don't know for sure yet but I've taken the temperature probe out and it seems to be open-circuit. I turned the oven on with the temperature probe disconnected and got the same error. I would try replacing it but De Dietrich inform me the part is obsolete, so I guess so is my oven :-o
