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,

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

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,

Hi

I suspect a loose connection or dry solder joint on the front panel.
Try setting the temperature to 200 then hitting the front panel. If
this causes the reset, then you have identified your problem.

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.

Sigh

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.

There is no month 20 in the UK date format (or any sensible date format).

Drat - and I managed to keep my urge to post something like that under
control. :-)

I know (and agree) but that's how Google groups displays the date. Turns
out that on the forum the "encrypted" date is converted to March 20, 2007
which is clearly still too baffling for the forum users. ;-)

Hi, I know this thread has been open for some time but I I'm still think it
worth adding to it with what may well be an answer to the question, even after
9 years. I have had the same problem this past week. Every time my wife set
our NEFF oven to "top and bottom" and adjusted the temperature down from the
default 170 to 150 the oven paused before the C heating digit lit up. The oven
then heated and after a few minutes reached 150 and the heating light went
out. When the oven then required a boost, the C came on again but flashed and
the 150 reverted to default 170 again.
Eventually my wife gave up on dealing with this and carried on with Circotherm
which was working properly.
Later during a conversation with our son, he suggested turning off the oven at
the mains and leaving it off overnight. I didn't give this much hope but tried
it anyway. Low and behold the oven settings are now back to normal, the
heating digit lights immediately and the chosen temperature setting is
maintained.
This may not work for everyone but it is worth a try before committing to a
hefty call out fee.
Hope this helps someone as this was one of the few threads I found on the
subject.

This solution works for many electronic devices. Computer, phone,
sewing machines, modem, cable box, etc. Overnight is not needed,
usually 15 seconds is enough.

You are forcing a 'cold start' on it, and if the software is in an
uncertain state that SHOULD restore it to normal.

Note that random cosmic rays carry enough energy to occasionally corrupt
DRAM..

And any serious EMP from switching or transients on the mains can do
similar.

Going back to the original IBM PC, this became known as 'BRS mode'.

Big Red Switch.

Not quite as good as the (different) LBT from DEC.
