I have a Master-Bilt walk-in freezer. The temperature is supposed to be at -10 degrees. The freezer will start but shuts off at 0 degrees and will not cool down enough. The compressor runs hot. Please help.
If the temperature drops to zero and no more (water freezing point) - could be that there is moisture in the system and this freezes at zero degrees blocking the expansion valve (valve where the pipes join at the inside coil). If this is the case you will need to get a refrigeration technician to open up and help you.

Re: Master-Bilt Freezer doesnt cool enough
The only thing I could suggest is looking at the evaporator (inside coil / cold bit) and making sure it is not frozen over reducing the airflow through the coil. If it is then put it onto a couple of defrost cycles to clear the ice build up. Not sure exactly of this type but would assume you also have a sight glass on the external unit, you can check this to see if when running the sight glass is clear (fully charged). Another check is looking at the compressor and the larger of the two lines (suction) should be cold back to the compressor (this line is normally insulated). However I would suggest your best course of action is a good refrig. techy. Hope this helps.

Not really. Domestic refrigerators are designed to operate in an environment where people live.
Most all manufacturers recommend that they not be placed in an area that goes below 55 degrees.
At any temperature below that it starts to degrade.
Cold enough and it will not work at all.
The reason is once the fresh food compartment reaches it's normal temperature of 33-37 degrees, it shuts the whole machine off.
That is by design, on any refrigerator like yours that has only one compressor and cooling fan motor.
As well, there are other issues. In that situation, the machine could well stay off 12 to even 24 hours.
The compressor has an oil sump in it, and the oil becomes very thick. When it finally tries to start, it creates a very stressful situation for the compressor, and could substantialy reduce it's life.
If the temperature fluctuations occur (at least the ones to 20-30 degrees) at intervals of 6 hours or so then you are catching it in it's defrost mode which occurs on a timer. The timer shuts off everything except lights every 6 hours for an average of 20 minutes. This usually isn't enough to thaw things but I have seen it cause some crystale. Look closely at the back inside wall of the freezer for an accumulation of frost. If you see it there then you may have a defrost problem. Usually this is accompanied by steadily rising temperature in the freezer and fresh food secions both. The temps you listed (0to10) are fine. Good luck, AJ
We ahve a two year old Frrigidaire Freezer. every year same time it seems to correct itself(?), like self defrosting etc, and takes a long time come back to its cooling level. This is made in brazil G series. Please help.
If it started to cool again the compressor was running. Check the condenser and make sure it is clean. Provide as much air movement through the garage as possible . 100 degrees is a high temperature to be operating a refrigerator in.
