Model no 253.5711860 side by side the freezer will not stay cold enough. builds up ice, changed computer still did not fix. When weather colder freezer colder

Check the freezer door seal is not leaky. Look for signs of moisture condensation along the door. Apply a thin film of Vaseline along door frame. This will make door seal stick better.

Also check there is no ice building up in freezer. This is a self defrosting fridge and built up of ice inside means warmer temperature. Lower the use of ice cubes from the ice maker to reduce load on compressor as this can effect freezer temperature.

Check freezer is not full of too many items causing reduction of air flow and hence reducing cooling effectiveness.

ck the fans they may not be running . als ck for frost build up in the freezer ( back wall .) you may have a defrost problem and it's blocking the cold coil .. mm

the higher the # the colder the frig should be . / if ice cream is not hard the freezer is not cold ennogh . so clean the coiles and ck the two fans . also look in back of freezer side for ice build up there should not be any frost on back wall . if so you've found the problem . which is a defros problem .. mm

I think I can assume the freezer isn't a "frost-free".
A short physics lesson; hot air holds more moisture than cold air; hot air will flow from a warm area to a colder area, and the colder area will cause the moisture to condensate and freeze(if colder area below freezing, as a freezer should be), causing frost build up.The more often the freezer is opened, the more frost will build up.
Now for 3 possibilities:1) If it is a self-defrosting type, check your defrost timer control...not working, or not working often enough.2) Door seals damaged and need replacement.3)Make the kids stay out of freezer.

assuming fan now working. clean out vents/ drain holes (make sure no ice in bottom of freezer or in fridge unit)i.e. a total defrost.then check door seals all okay(no air leaks) if unit was trying to defrost itself and you reset to colder it will need to reset itself.....

Ok do this. Boil some water in a pot then use that to defrost the freezer. This is caused by ice build up in the vent that is keeping the cold air from coming into the refrigerator. Make sure it is defrost completel though cause the ice that is built up is mostly inside and can't be seen. That will solve ur problem I guarantee. Then set the temperature to normal. Like half way. This keeps the frost from building up. Believe it or not as refrigerators get a bit older they actually get even colder and therefore frost build up is more likely. Since no refrigeration can be made completely leak proof, small amount of the freon has leaked out older fridge, and this actually cause it to get colder. You don't need a service technician just defrost then set to a lower setting thats it.

If the freezer is staying cold it sounds like a defrost system problem. A bad timer, heater or thermostat can cause frost to build up on the coils and block air flow to the refrig side. Check out ACMEHowTo.com for troubleshooting the defroster problem.
There is a small duct between the freezer and refrigerator side if this is blocked the frig side won't cool.

this is usually a problem with evaporator fan not turning when the unit is running.check the freezer compartment and listen to the fan if it running. if it is not running it needs to be replaced.one good indication is ice or frost build up on the rear of the freezer compartment

turn it off for 24 hours it has an ice build up

hi. thanks for the question. the drain tube that goes down to the drain tray is clogged. turn fridge off .pull fridge from wall. remove back panel clean all coils. let it thaw with doors open, it will thaw quiker. when thawed, clean the drain tube. this will solve the problem. thanks the appliance doc
