I have had this little freezer for just over a year, it worked great until recently it started to frost heavily on the coils. So I emptied it, defrosted, and then filled it again. After it seemed fine for a couple of weeks, it frosted heavily again and all of my food was soft, the thermometer read 32 degrees F.
Called LG warranty repair, the technician couldn't see a problem because it was at temperature at the moment he checked.
I purchased a sensor which gives minute by minute readings of temperature and humidity. The temperature is hovering between -3 and -4 degrees F, which is fine. The humidity though is scaring me, it reads between 30% and 60% humidity, which makes no sense because I'm in the desert with ambient humidity of about 15%. Any ideas what could be causing this excess humidity?
