I’ve had my kegger bar built for about 14 months now. When I first built it the keg box with the 2.7 haier fridge (compressor in the back) was working extremely well. I even got it as low as 28 degrees once and it would hold it at 34 without a problem. I have the frost issue every once in a while, but thats whats gonna happen. I have 4 PC fans to assist the cooling. 1 fan in the fridge in front of the freezer compartment, 2 fans on the side of the fridge blowing the hot air around the fridge out and 1 fan on the compressor.
Now, it may get under 40 degrees when the freezer is freshly defrosted, but then it quickly deteriorates. No matter what setting I put it on, I can’t get it to go under 43/44.
Is it possible over time that a leak in my insulation developed? I’m definitely getting frost on the fridge, so that means it’s working correctly, right?
I’m probably going to go through the insulation this weekend with one of those temp guns, but I have no idea what I should be looking for… how would I recognize a insulation problem using one of them?
sorry for the long message and thanks in advance

Massa…
Sorry for the delay on responding…
Did you figure this out yet?If you have frost, your good. Where is your temp probe?
How often are you peeking?
Is the box empty or fully loaded with a new keg?
Is the door fully sealed?let me know either way…
sorry it took me so long for updates….
oh boy did I figure it out
Before I did something stupid like rip out the insulation from the inside, I decided to add another pc fan and move the existing fan to a different spot. Previously I had one pc fan in front of the freezer box that pulled cold air over the freezer box into the keg box. I decided to move that fan behind the freezer box so it would push the air over the freezer box. I also added another pc fan in the bottom corner of the fridge that pushed air to the other fan behind the freezer box. This definitely improved the air circulation withing the keg box, although not ideal it’s still better than what I had before.
My keg box door always sealed great, but the weather stripping would always push the box out a tad, especially closer to the hinge where it gets compressed the most. I’m only talking a couple millimeters here, but I had no idea what was causing my problem, so I decided to fix that too. I added a latch to the door so it shuts completely now.
end result…. WOW. Set the fridge to the medium setting (3.5 out of 7) and the min temp it hit in the fridge was 25 (With a completely empty keg box and the temp sensor in the far bottom corner). Turn it down to 2 of 7 and it hits 28. I now keep it just over 1 of 7 and it bounces around between 32 to 34. The frost level is very minimal too.
PERFECT!
