Used freezer won't freeze food

Please keep in mind here that this freezer is 35 years old and it will eventually reach a point where it will be easier to replace it.
All freezers and fridges click, rattle and buzz as they cycle through there job. You only really need to worry if the noise is louder, random or is constantly happening. Some older freezers have a 'Boost' switch where you can turn up the freeze rate if you have recently put a large amount of food into the freezer. Don't use this all of the time as it is expensive to use and can wear out the freezer parts faster. Try flipping this switch and leaving it for 5 minutes to see if the noise changes.
Has the freezer been moved recently? Sometimes if a fridge or freezer isn't level it will make extra noises.
Is the freezer still as cold as it normally is? The noise could be the evaporator fan starting to fail. Get a qualified technician look at it as he will be able to listen to it and give you better advice.

Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

first of all unplug that freezer and wait for 15 mins. move it five feet from the wall. after 15mins, plug it back and kick in compressor at the same time!!!! remember plug and kick at the same time. the ckicking noise come from the starting relais. this says that the compressor has a problem. If it doesn't work ; you will have to call a service person who will replace the compressor for you.

Can't help I'm afraid, but we have exactly the same problem with exactly the same model. Ours did work for nearly 2 years, but recently only works with the boost button pressed in. I suspect the thermostat is not working as the boost button over-rides the thermostat to give max cooling. Your freezer is new so get it exchanged; it certainly doesn't need to be full to work!

how hot is the compressor? a very warm to hot compressor indicate dirty coils or lack of refrigerant

Sadly these old freezers use way too much electricity. You will be better off junking this one and purchasing a good used or brand new one.

Move the refrigerator to a room that is at least 50 degrees F.

Temps on most refrigerators are regulated by the fresh foods temp. If your garage is let's say 35 degrees, the fresh foods temp will most likely never raise enough to turn the refrigerator on. With the refrigerator never running, the freezer compartment will warm to 35 degrees, resulting in everything melting. Even if garage is a bit warmer, say 45, the refrig will not run long enough for the freezer to maintain a low enough temperture. If the garage temp falls to below freezing, say 20 degrees, the food in the fresh foods compartment will freeze. (outdoor beverage dispensers have internal heaters to prevent product from freezing !) Please don't rate this if not a Fix-Ya for you, as anything else lowers my score.

did your friend use a knife to prize off lumps of ice? i bet he/she did and has punctured the evaporator. if so, not repairable

If this is not a frost free unit. I say replace it. I don't believe in recharging a deep freeze. You can never really trust them again. The food inside is worth more than the freezer. If this is a frost free unit, See if the fan inside is working. This can also be a defrost system proplem such as a timer and well worth fixing.
