Hello everyone!

I have had my keezer built for about a year now and it has worked wonderfully. Got to the point where I was happy with it and just left it and started pouring pints. But now I really want to dial in the temperature and cut back on the compressor cycling so much so… my questions are:

1 - Where should I be placing the probe? Many threads have stated, taped to the freezer wall, to the keg, inside a bottle of water etc…
2 - How high/low should I set my temperature differentials? My main goal is to have it cut back on cycling so much. Its an older freezer and I don't want the thing crapping out on me. Ive noticed lately its been heating up on the outside…

The collar is only insulated with silicon caulking along its inside edges. Would it be worth getting some foam insulation? Any info here would help me!

I am looking at running this keezer from 38 degrees F to 40 degrees F

I don't have a keezer myself so can't really help you on question 1.
As for question 2 I would say it depends on where you end up putting your probe. Assuming you put the probe in a bucket filled with water you will see very little fluctuation in the temperature reading meaning you will be able to set a much smaller range on the controller without having it turn on and off constantly. The opposite is also true, if you leave the probe exposed to air you will see faster temperature changes. To balance this you will want to set a bigger temperature range on the keezer to keep it from turning on and off to often.

I filled a mason jar with star-San, drilled the top, and placed my probe in the sanitizer - has worked that way for years. As far as differential goes, I have I'd set to 2F, can't say I notice it cycling a lot.

Hope it helps.

Thanks for the tips gents! At this point I'm kinda just going with the flow haha. I think a fridge will be next… Don't have to worry about temp controllers.
