In about the last 3 days, the freezer, on my Hotpoint CTF21GAB, is not getting cold enough and food is thawing. The refrigerator portion seems to be cold enough. No ice is being made in the icemaker. This refregerator/freezer is about 15 years old and the only bell and whisle on it is the inside icemaker. I have read a solution to another brand and will try with the basics (clean the coils, look for obstructions). I can hear a fan running, but will pull the frig. out to visually inspect. I am getting a layer of ice on the inside-top of the refrigerator that I did not get before. Could anyone give me some more troubleshooting tips to find the troubled part? Thank you

Many residential refrigerator / freezers are designed to work at temperature considerably above above freezing. Most modern refrigerator / freezer have a single electric thermostat - located in the fresh food compartment. This lone thermostat will control the compressor to keep the fridge (fresh food) section at the desired temperature (usually between 34 - 38 degrees F). The freezer will get colder regardless of how cold it is already whenever the fridge thermostat turns the compressor on.
Now that you see how the thermostat works, let's look at what happens when the fridge is placed in an unheated space - like a garage. In winter time, the temperature can drop considerably below 38 degrees. If the outdoor temperature remains cold enough, for long enough - it will affect the thermostat in the fridge. The temperature inside the fridge could drop below 38 degrees, preventing the thermostat from telling the compressor to turn on. Meanwhile, the temperature in the freezer compartment slowly rises from the normal -10 to 0 F degrees. It will continue to rise until it is the same temperature as the fresh food compartment or until the thermostat in the fresh food compartment tells the compressor to turn on again. This means the freezer contents will thaw.
If the temperature in the garage is even in the 40 to 50 degree range, the loss of cold in the fridge may not happen often enough to keep the compressor coming on often enough to keep some freezer items frozen solid - such as ice cream. Remember, water freezes at 32 degrees F, other products may require lower temperatures to remain frozen, and could thaw at 28 or other temperature.
Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong.
If you are hearing a clicking or buzzing thencheck out the last two tips.
If your refrigerator is running but warm, then...
Check out these tips that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...
Hi.. feel the dividing rdge between fridge and freezer.. is it warm?.. chances are that the little fan at the back of the fridge freezer that helps cool the compressor, has snagged own it's own wire... it's a weak fan, like you get in a computer, but it does a lot of work.. without it, the coolent does not do it's job, which results in your device not cooling things properly
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.....
If the noise was coming from the compressor when it was cutting off or starting, it was the internal mounts of the compressor and the compressor will have to be replaced. If the noise was a fan, it may have stopped. One is in the freezer behind the rear cover and one is underneath where the compressor is behind the cardboard cover.
