I Really Need Help with my Johnson Controls A419.

(1/4) > >>

patrickswayze:
Hey guys i just received a Johnson Controls A419 Unit this past weekend from Amazon and today i plugged it in to my Haier Chest Freezer for the first time. I plugged in the following for the device

Setpoint: 63'F
Differential: 1
Anti-Short Cycle Delay: 1
Temp Offset: 0

I have the probe suspended in the middle of the freezer. The freezer itself is set to its lowest setting. The problem i am having is that when my control turns off the freezer at the 62-63'F mark it keeps dropping slowly all the way down to 51'F or so. I WANT TO RIP MY HAIR OUT this is soo frustrating. Please, can anyone help me out here, why is this happening? It should be only a degree or two off from my setpoint.

It may continue to cool a little bit, but that's a lot.  How big is the freezer?  What else is in the freezer?

Right now their is nothing in the freezer as i am testing it out before brewing this Friday. The freezer is 7.1 cubic feet. I plugged in the A419 when the freezer was off. Should i have connected it when freezer had already been cold, so the air would be relatively universal?

So I had to pour a glass of wine to think about this. If you left your freezer unplugged and put the probe inside, what would the temperature be ? If you come back with any number under 63 then I think you are expecting your freezer to be a heater. Not sure that works. Seems that even if you tell the freezer to shut off at 63 the coils and condenser are still cold.  So if so, how about the light bulb in the paint can to heat it up and skip the freezer ?

Plan B, drop the setpoint way down and use it for lagers. Not sure you need a freezer for ale temps.

But if I knew what I was talking about I would probably be drinking homebrew.

My temp in San Diego is around 86'F and was about 78'F in the freezer before plugged in. Im just asking for some assumptions or personal experiences to help me in why when the freezer turns off at my setpoint temp but the temp still drops so dramatically after the freezer has been turned off. Probe location? Should i place a glass of water in the freezer and place the probe in it? The manufacuter is no help so im trying to get help from the community who has first hand expeience. This is prolly the one post i meed the most help in! Please! If it sounds like i am begging, its cause i am
