FREEZER WILL DEFROST AND THAW OUT FOOD. THEN WILL START FREEZING AGAIN IN A COUPLE OF DAYS. THIS HAS HAPPEN 3-4 TIMES IN LAST 6-8 MONTHS. WHAT COULD BE PROBLEM?

This information does not mean anything to us if you didn't specify the model. In what temperature range a freezer works we knew thanks to the stars.
One star (-6 degrees centigrade) is perfect for making ice cubes and is sufficiently cold to keep food for three or four days.
** Two stars (-12 degrees centigrade) stores food for fifteen to twenty days.
*** Three stars (-18 degrees centigrade) will keep food safe for up to three months.
**** Four stars (below 18 degrees centigrade) means that the compartment provides the ideal conditions for freezing down fresh and pre-cooked foods.

You have a problem with the ADC.

Frigidaire has also jumped into the market with an adaptive defrost board. The fresh food section light switch and light bulb must work. To initiate a defrost cycle, open the door and push the light switch in and out 5 times within 6 seconds. The compressor and fans should shut off and the defrost heater should come on. Open the door and push the light switch in and out 5 times within 6 seconds to remove the refrigerator from the defrost mode and back into a cooling mode.

This product comes equipped with an Adaptive Defrost Control (ADC). To activate manual defrost, press and hold the Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. A "d" in the freezer temperature window and "F" in the refrigerator temperature window will display when the heater is activated. To deactivate manual defrost, press and hold Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. "d" and "F" will be displayed until the defrost cycle is complete. (approx. 8 minutes)

keep the door closed by all means any small opening can leave the freezer start to defrost slowly without you knowing it

check the engine and pipes.cooler

I am no pro on these but it sounds like your defrost heating coils are coming on to often. You may want to check them. Aslo just for good measure>>>
Is your circulating fan working?
Sometimes they stick and need a shot of WD 40 and then work
it back and forth a little until it wants to take off again. Keep me informed
and PLEASE give a Thumbs Up for the effort. The Raz Shack

Hi. I am Kelly and welcome to FixYa. Here is the real question..... Is the food staying frozen?

Freezers usually defrost 3 times a day (8 hr intervals) Some as often as 4 times a day. The freezer use concept is that it is not opened more than 3 times a day. (Yes there will be more times than that any given week)

Having said all of that.... some things to look at.

1. Check the door seal for any signs of tears... grease... collapse...

2. Make sure there are no gaps in the door or between the closed door and the seal.

3. Many people don't check this one... but make sure it is level. An un-level freezer can cause the door seal not to function correctly.

Now if your saying that the food is actually defrosting... then there are a few other things that can cause that.

A. Sticking / defective Defrost timer

B. Defrost element is not heating and the freezer goes through a VERY long defrost cycle as the contents have to reach 60 Deg F for the 60 Deg bi-metal thermostat to close and advance the defrost timer to start the compressor.

C. Intermittent operation of the 60 Deg thermostat

I hope this clears things up a bit for you.

Thanks for using FixYa.

Yes that is the correct part number.
If a new cold control does not correct the problem. Replace the compressor start relay.

check your defrost timer

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.

your food should not thaw in a frost free freezer. but I can not tell you why it is thawing, sorry.
