I have a 5cu ft Holiday Chest Freezer for my corny kegs.
Use a Johnson Digital Temp Controller set to 38 degrees with the probe in a thermowell in a Gatorade bottle of water.
I have a Eva-Dry 500 to control moisture, but I'm still having problems with moisture and now a small bit of mold was spotted and cleaned thoroughly.
You can see in the pic how the temp probe is being fed into the freezer.
There is a small gap in the seal allowing air to enter and causing the moisture which is all on the top of the freezer only on the tops of the kegs and regulator.
Any advice on how to feed it in without a leak?
