Question about Bosch HBL 435 Stainless Steel Electric Single Oven

Open Question

I have a Bosch hbl435 electric wall oven. The time started fading the other day and yesterday it went dark. We were able to use the oven but not its totally not working. I took the panel off and when I did the screen came back on. The oven would work as well. When I pushed the panel back in it went off. Arghhh! I looked for loose wires but didn't see any. When I moved the panel back and forth the screen would flicker on then off. Now it's totally off. I can't get it to come back on at all. Any ideas? Main mother board? Bad relay? Thanks for any help or suggestions,

If the fan is working o/k, then it is sure to be the oven element that is faulty, a common fault with fan ovens, replace element, and it should be o/k.

Either you have not refitted the door back correctly, or the door hinge springs are weak, a common problem.
This being the case, then the only solution is to replace door hinges.

Welcome to FixYa,

I'm looking at the diagram for your oven and I do not see a P17 connection, however you said it is a connection on a relay. Can you identify which relay it is connecting to i.e. K5, K3, K7 or K8 ?

K5 is the bake element or "DE" ( down ele. )
K3 is the convection element or "RE" ( ring ele. )
K7 is the inner broil element or "RE" ( internal up ele. )
K8 is the outer broil element or "EUE" ( external up ele. )

I should be able to help move you forward in this regard if you can clarify this matter. I'll watch for your reply.
