I've been suspicious that both ovens in my Neff U1661 are no longer
getting to the set temperature so have just checked with an oven
thermometer - it shows 20-30 degrees colder than the setting in each oven.
I'm going to try the thermometer in another oven ASAP but I suspect it's
telling the truth because we've had some under-cooked things recently.
Are there any calibration adjustments on the temperature controls?
Any suggestions on what to check?

(I've asked this on UKwhitegoods too)

Some oven thermostats can be adjusted but a lot can't. (Screw on the back of
the control knob "box")
Adjustment was a large part of manufacutring costs, a lot made now "self
adjust" during manufacture.
A lot of research was done into this aspect.

You might still be able to buy general purpose oven thermostats as a
replacement which are adjustable.
