I received my ICECO VL45Pro S on Tuesday. Everything looked good no damage to box or unit in shipping. However, just to be safe I let it sit for 24hrs as per your operations manual. Yesterday evening, I plugged it into A/C power and set it on MAX and temperature to 32 degrees Fahrenheit, once it reached that temperature and held for a few hours I dropped it to 20 degrees Fahrenheit and again after a few hours dropped it to 0 degrees Fahrenheit. However, it took a long time for it to finally reach 0 degrees and it sat on 2 degrees Fahrenheit for about 3 hours. Finally, it did display had hit 0 degrees Fahrenheit and I heard compressor drop in noise level. Today, it again reads 2 degrees Fahrenheit and just stays there with compressor running obviously trying to get there but not able too do so.
Also, even though on the refrigerator display indicated that it had reached 0 degrees Fahrenheit I quickly opening it and using a calibrated non contact laser thermometer the lowest temperature I could measure was 15 degrees Fahrenheit at lowest point of the large storage space. So my question is why is the display showing 0 degrees but the inside temperature is 15 degrees or more higher? I just placed a Tempi.Fi Bluetooth / WiFi sensor in it same spot to see what live data I get back.
You need to leave the thermometer in the freezer to do an accurate test, because otherwise you are measuring the air that is mixed in with outside air. Everything else you described seems normal though.
Assuming this is initial cooling, getting to zero the first time can take a while as it has to change the temperature of the inside walls by quite a bit.
As to why it was on 2 after already hitting zero, that’s just how these things work. When you turn it on the compressor will bring it to about 2-3 below the temp you set it at then compressor will shut off. While it’s off the fridge will naturally climb back up, and when it reaches about 2-3 above the temp you set it as, it will come back on and cool it back down to 2-3 below your setting. Since it’s set to zero it will just go until zero instead of -2 to -3, and cut off. At 2-3 it will come back on and bring it to zero; Should not take that long after initial cooling is done, unless you live in the middle of an Arizona desert during the month of July.
Anytime you are plugging in a fridge/freezer for the first time, it will take a while to bring the inside air and walls/fridge itself up to temp, then after that it’s much easier/lower consumption in order to keep it running. The closer to freezing the slower the rate at which the temp will change as well, as it has to do the most work during that range.
