    Having the same problem. Check the 1st page of the manual #11. It states not to keep anything in it below 40 Degrees and most meats, fish etc. need to be kept at between 33 Degrees & 40 Degrees. Mines been running constantly on High. Im returning it to Best Buy.

    Saw one suggestion to check the power to the compressor, but
    these little Peltier coolers don't have one.



    In a thermoelectric cooler heat is transferred using an electronic Peltier
    Device (an array of Peltier diodes), not a Carnot engine. They are not nearly as electrically efficient
    as your grandmothers Fridg, not yet anyway. But they have no moving parts.
    Readily available, and affordable, commercial devices today can generate a
    temperature delta of 70 degrees C.



    The ability of these thermoelectric refrigerators to cool is dependent on a
    real good seal. Compared to a traditional refrigerator they don't have much
    cooling power. Pre-Cooling things before you put them in is an excellent suggestion.
    Leaks and opening the door frequently
    will heat them up in a hurry, so will putting a bunch of warm items in all at
    once. However, mine is new and the seal
    is perfect.



    Their performance is also dependent on the ability of the exterior heat sink to
    reject heat and the interior one to collect heat. It won't work if the
    refrigerator is kept in a hot environment, if ice forms on the interior heat
    sink, or the outside one is covered with a blanket. It is also possible that
    there is not a good thermo-mechanical connection between the device and the
    heat sink on one side or both. If everything else seems to be fine, you could
    pull off the exterior heat sink and see if the device underneath is cold to the
    touch. If it is, then you could tightly remount both heat sinks with a good
    thermo-mechanical grease or adhesive between the device and the heat sink. Mine new and kept in a 70 degree F, low
    humidity office so I don't have a mechanical problem.



    It is also dependent on enough current getting to the Peltier device, and the
    device working. The voltage across the device should be 0.8 – 34 VDC and the
    current should be 1 – 20 A, typically the higher the current the higher the
    voltage.



    If that is your problem, and there is nothing clearly wrong with the circuit,
    like a blown fuse or popped cap, you are going to need a schematic and some
    knowledge of electronics to troubleshoot the circuit board.



    I suspect the circuit will have a constant current source for the device, and
    that the current source is turned off and by the temperature sensor, much like
    a regular Fridg. But a schematic would be real nice. That's what I 'm looking
    for, a schematic. Good Luck.

I bought one of these for the basement. It states it is designed to cool 20-25 F degrees below surrounding air. This works well in the basement. Mine gets into the mid 30 f range and the basement is about 70 F. Pop and beer stay good and cold . Best if you pre cool before putting it in the frig. This frig is a thermal electric unit and has no compressor or refrigerant, Will not work well in a non air cond area. It is make like the plug in cooler you can plug in to you car cig lighter. This doe's work well for what I am using it for but I wouldn't try to keep meat in it just beverages and such.

Can I remove the freezer unit from a Haier HSB02 unit? I would rather have more refridgerator space.


No you would probably be breaking into the gas system which would render the fridge useless.

Fridge will not get cold


Was your fridge transported upright at all times? There are warnings on most brands not to lay them down due to potential damage. If that was not the case, those small units are often easy to repair.

[Note to garing: The person said there was no ice anywhere but on the back. Dorm sized refridgerators are rarely frost free, so your answer was pointless.]
