Is this a bad circuit board? (fridge)
Its the type that uses the resistance probe. Which is all fine and dandy. I have not measured the ohms but assume its measuring accurately. Lets pretend the temp probe was hanging off the fins. Re...

I think i have a new question. Will often makes threads that are too long and confusing. (edit...it just happened again below. sorry)
Can we talk about how the cooling fins are getting colder? Which effects the air temp correct? I have a fan blowing directly onto the cooling fin where the temp probe attaches.
I want to believe the fridge will keep the electric element ignited and hot, until the temp probe gets cooled down to a certain level. I understand that the cooling fins will reach this low temperature before the entire fridge is cooled. But the part im confused about is below:
1. With the fridge doors closed for days at a time, and 3 fans blowing inside my fridge, why does the electric element turn off while the air temp inside the fridge is 40+ degrees? Remember doors are closed for days and lots of air circulation. 2 fans on the fins and 1 fan on the lower shelf blowing upward. I would expect my graph to show a more consistent lowest temp. I consider the probe a mechanical device. It works or its broken. While the circuit board can have a mind of its own. Terminator style. Im no stranger to circuit boards i will be soldering our home oven circuit board today. No joke will take a pic. The display died. A couple resistors are super hot and burned the board. Looks as if the solder joint is wiggling where it hits the board. I can tell a repair took place there because the solder looks chunky and different. It was a used board bought online a couple years ago. I think their repair came loose.
Hows that for confusing a thread?
I enjoy thinking. Its fun when you guys tell me im wrong. Not the first time and wont be the last. Thats how you learn is through making mistakes.
