I recently purchased a Bosch 800 Series Wall Oven and since the first day that I had it, it would randomly shut off. This seems to happen more often in the afternoon and evening/night than in the morning. For example, yesterday morning the oven ran for 3 hours without any issues. Right now I can not even get the oven to turn on for more than 3 seconds (it was not used at all earlier in the day).

When I try to turn it on, it will start to preheat and then stop. When it stops, the clock remains on and there are no error codes displayed. It is as if I hit the "cancel" button to stop it from cooking. Sometimes when I try to hit the Bake button (to start it up), I receive an error sound from the oven and no error message is displayed. Again, this seems to happen more often in the evening/night than first thing in the morning (as strange as that sounds).

I have already had both control boards replaced and the problem persists. I don't know if I have an electrical problem (the previous oven worked fine) that seems to only manifest towards the afternoon/evening, or maybe there is a short somewhere in the oven? I'm at a loss.

I've only found one other person with a similar problem and their experience seems to mirror mine. Unfortunately, there wasn't a resolution in the post (below) and I have no way of contacting the original poster to see how things turned out:

Does anyone have any ideas? Thanks in advance!
