I HAVE MY FRIG IN GARAGE CAN I PUT THE TEMP ON 4 OR 5 TO COOL BETTER

If the door temp is reading low then it will not cool as that is the temperature the fridge thinks it is at (regardless of the real temperature). Try setting the door temp lower and see if there is still a 14 degree difference between the 2 readings. If it does cool down further and the difference is the same then I would suspect the thermostat.

There is a TSB on this (TSB) = Technical Service bulletin. You need a service company to order part number W10599551 and put it on. This will fix the problem.

Check to make sure the fan or fans are not blocked, and spinning.

If the ambient temp is below 52 degrees the unit will not work properly throught the cycles you will need to get what is call a garage kit to install in the unit.

Since refrigerators were designed to run in your 72° kitchen, when you put a fridge outside, where its colder than normal operating REFRIGERATOR temperatures, i.e. 35-40°F, because that ambient temp is colder than fridge temp, the thermostat in the fridge section reads it as normal temperature, and does not turn unit on. it does not read what the freezer temp is. You have a couple of choices: bring the unit inside, heat your garage, or only use it for pop and beer in the summer. You can reply here or send me a question from my website: www.FixMyFridge.net

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.

Since the temperature is already 40°, the cold control is satisfied and will not run. Thus the freezer will warm up to 40°.

Maybe over pulling more amps the the GFCI curcuit can handle. Check all the GFCI plug and verify if there are anything else plugged in. Including hair dryers and / or flat irons.

The damper is not opened and closed just by control movement alone. Your control connects to the damper by a notched plastic band. The damper also has a temperature sensor on it. To check damper operation set control to 4. Hold an ice cube to the temp sensor (a coil of small aluminum tubing) and the damper sholud close. As long as the fresh food comprtment is calling for cold air, the damper will remain open reguardless of control setting.

The fan that blows cold air from the freezer to cool the refrigerator is not working. If your a little handy with tools its an easy fix. Its located in the freezer. Open your freezer door take off the steel panel at the back of the inside of the freezer. After you remove the panel you will see the fan the blows the cold air up to the Frig. A quick trip to a local appliance store for a new fan with do the trick. Put in the new fan 100% fixed even better than new because the orginal part is defective Kenmore should have recalled them. I have the same frig and its been perfect since I repaced my failed fan.
