I just got a 7+ cubic foot chest freezer and a digital controller:http://www.northernbrewer.com/shop/brew ... oller.html )
I adjusted the set point to 50 degrees, and the Differential to 1 degree. I left the other settings at the factory set value
I hooked it up, and it settled in at 50 degrees over the course of the night. But, I went back down to put some bottled beer in it, and noticed it was at 42. I opened it up, and warmed it up. Let it go again, and it dropped all the way into the upper 30’s.
Basically, I think what is happening is that it is cooling down so quickly, that by the time the temp. probe registers that it should shut off, the temp. it cold generated continues to lower the temp. well past the set point. Then, it slowly creeps back up to set range. When it hits the setpoint, it comes back on, overshoots the temp and cools down a lot lower than it is supposed to.
One main question - where do you put the probe? I just have it running in and hanging from the basket. So, it is just sort of hanging in the air in the middle of the freezer - should I put it somewhere else?
Or, is this just normal, and if you avoid opening and closing the freezer, it just settles in and stays there. Whereas anytime you open the freezer and it kicks on it is going to tend to overshoot the temp? Any thoughts? Am I doing something wrong?
