hi
This the thermistor plot 4.7K @ 25C, so it fits nicely with what you have found in practice.
I wondered why our two readings differed.
My head is hung in shame LOL
I'll look at pcb.

EDIT: the etch looks OK, its not the way I would do. If you are confident you will get no solder bridges try it.
No will revert to purely the tracks then, better safe than sorry
Most domestic fridges dont work to a 1Cdeg tolerance, providing the tempr stays lower than 5Cdeg, the recommended temp for keeping food cool and higher than 1Cdeg , so it dosnt freeze your milk, I would settle for that.
So i'm being a little pedantic then LOL?
