How will you KNOW that the "replacement unit" contains the desired "fix"?
I.e., does the part number change to reflect the fix? Or, do you also
need to know a *revision/version" number??

Because mine is so way off that pretty much anything would be an
improvement! My grub came out so undercooked that it was ruined and after I
changed the thermostatr itself, the temp now wavers from 50 degrees too low
to 200 degrees too high.

So, are you convinced that your unit is *defective*? (i.e., "in need
of repair") Or, do you just think this a bad design?


50 deg too low to 200 too high and you're asking if he's convinced
that it's really broken as opposed to designed that way?

Good grief.





It's hard to say whether your problem is in the heating element, sensor
or controller. Until you can identify some *actual* behaviors.


He did define the behavior. It's not the heating element, because he
said it went 200F OVER. Beyond that, behavior isn't going to tell
him whether it's the controller or the sensor.



There have been appliances with known design flaws (I can recall a refrigerator
that was notoriously warmer than the controls *thought*).


Did it get 200F hotter, 50F colder?
