It seems that no matter what Ido I cannot get the temp in the refrigerator to stay above 25............what do I do. I have lost the book and don't know for sure if I am even setting the temp right. It is digital I push the button till it says 37 but it always jumps back to 22-25.................
The 37 degree reading you're seeing is the temp. setting, not the present actual temp. When it jumps back to 22-25 its telling you what the actual temp is inside the refrig....simply wait about 24 hours. It should then read about 37...that is, the temp you set it at 24 hours previously.

If you have a frost free refrigerator then temp jumps as you discribe are somewhat normal during a defrost cycle. However it sound like your defrost temp may be getting too high. There is a limit thermostat on the freezer coils that keep the defrost temp from getting too high. The part is called a (defrost termination thermostat) and is a round disk about 1 to 1.5 inch in diameter clipped to the top of the freezer coils with 2 wires coming out of it. When cold, it allows power to the defrost heaters. At around 35/40 degrees it opens and shuts off power to the heater. 35/40 degrees sounds high for a freezer temp but that is behind the wall and only for a short time. Yours may be staying on too long or out of temp calibration needing replaced.
Most likely one or both of the thermistors are bad. Usually pretty easy to find behind a vented cover about 2" X 1" on the side walls of the refrigerator and the top of freezer (if freezer is on the bottom of the unit)
hello. this is a common problem. The thermostat for a refrigerator/freezer is in the refrigerator part. Normally the refrigerator is kept at around 40 degrees. The compressor turns on as required to maintain this tempearture. The evaporator coils are concentrated in the freezer side, so that the freezer stays at around 0 degrees while the fridge side is held at 40.
If the ambient temp is around 25 degrees, the refrigerator compartment will get below the setpoint of 40 degrees, and gradually continue down towards 25 degrees. The compressor will not have to run at all to maintain this. In fact, the compressor is designed not to run, once the refrigerator compartment gets below the setpoint, for fear of freezing the contents of the fridge.
The lack of circulating refrigerant due to the non-running compressor means that the freezer compartment will gradually warm up to 25 degrees.
If the unit were just a freezer, it would work fine in the unheated garage. If it were just a refrigerator, it would not run in these conditions, and the contents would eventually freeze, but it is otherwise OK.
PS kindly rate my answer. Thank you.
refrigerators have 2 coils. the evaporator coil and the condensing coil. one is on the bottom of the fridg and one is on the back or inside behind a false panel. these coils must be kept clean or if the condensing coil cannot reject the heat absorbed by the evaporator, the box temp will stay high and if the evap coil cant absorb heat the box temp stays low running the risk of freezing
Make sure the vents from the freezer to the fridge are not blocked by ice etc. One is at the bottom and one at the top. The on at the top is adjusted open or closed when you adjust the fridge temp. Make sure it's working. Also make sure the fan in the freezer is circulating the air from the freezer through the vent at the top.
It appears that the defrost bi metal control is hanging up and during the defrost the temp in the freezer is going too high. It is supposed to terminate the defrost at around 50 degrees. This usually occurs in about 20 minutes, if the defrost heater stays on for too long the freezer temp goes too high. Change the defrost bi metal
