Bosch oven temp keeps resetting to 150


Anyone out there have an explanation as to why our Bosch fan oven should keep dropping back to 150 degrees?
It would appear that this is something of a default setting as this is the value that it starts at when you select the cooker. Bosch have only responded to my question by sending me a book the repairman form with no explanation at all...
Any ideas?
Regards,
S

How do you mean it keeps dropping back to 150 Deg . I ake it there is some sort of indicator of the emp?
On the subject of fan ovens I have an Indesit fan oven and had to buy an oven thermometer to see what the actual temp was .It was way different from what it was being set to using the switch on the oven Stuart

Does it reset during cooking? Have you noticed the display going blank or any other strange behaviour just before it resets?

There is a red digital read out. When you make an oven selection from the various combinations of elements and fans on one knob, the read out next to the other starts at the mid temp setting of 150 and you then turn the knob to get the desired red number above or below this mid point.
I had noticed the occasional sudden drop back from a high setting to the mid point during cooking. This seemed to be more likely to occur after the door had been opened and closed, and was a minor annoyance. Now it happens more often than not and means I have to stay in the room ready for it to drop back so that I can turn it up again.
I have not checked with a thermometer (don't have one that good) but do get the impression that it is taking a long time to reach my 220 deg C bread cooking temp - even before it starts to reset itself. However, I did let it do a 'self clean' and it got up to max and stayed there for 2 hr with no resets, so it isn't the elements.
Thanks for the interest to you both,
Cheers,

Is the oven temperature dropping - or is it merely the thermostat switching the input down due to it reaching its target temperature. Does it cut back in after a while _ try opening the door to loose some heat to see what happens.

Thanks to you both:
I had a go at banging it while making some bread yesterday, but, wouldja know, it didn't drop out at all this time. Fraid it's like that: waits for you to trust it and then ruins your whole dinner party...
I tend to agree that the poor contact somewhere is the probable cause. I have not had one of these peculiar modern 'decoupled' knobs apart before - i.e. where you turn it over a lot of 'bumps' but the dial does not feel as if it's joined to anything. (Not to be confused with the kind as on our washing machine, where the knob couples to the shaft when you push it in: the oven ones do push in in order to fit flush when not in use, but they do not push in to engage.) Presumably there are still some proper contacts in there somewhere?
Cheers for the suggestions,
S

Maybe you fixed it by beating it up. Ovens are basically cowards, and you taught it who's boss. It doesn't want to get beat up again.

Do any of you homeowners forumites know what that mysterious code is that you see in messages that looks a bit like this? "3/20/07"
The first few digits may be a bit baffling to you but the last two digits represent the year the message was posted. The return on chasing up messages that are 9 years old is gonna be near zilch. Try starting a new thread if you have a problem. It is allowed you know.

But it's probably the only one with the same problem. It's certainly worth a shot.
