Hi. my freezer isn't freezing food completely but is frosting at the back and freezing around the fan.

EXCESS HEAT IN A FREEZER WILL CAUSE COMPONENT "ICING"
1. REMOVE EVERYTHING FROM FREEZER
2. MAKE SURE ALL VENTS ARE CLEAR OF DEBRIS AND NOT BLOCKED
3. LET FREEZER COMPLETELY DEFROST...CLEAN OUT COMPLETELY ..RE INSERT FOOD AWAY FROM FANS, VENTS ETC..
4. FIX DOOR SEAL, AND DO NOT OVER FILL

One of the most common problems with freezers is their tendency to build up a thick level of frost and ice that can disrupt performance. The ice can form on the hoses and cause the fan to freeze up. While you want the freezer to be cold, too much ice is not good for the freezer or the food inside it. There are multiple reasons a freezer could start to develop frost buildup.

Freezer Overstocked
Frost can build up in the freezer if there are too many items inside of it. Air cannot properly circulate around the freezer, so the areas with the sitting cold air can freeze the moisture. Frost continues to build up and accumulate, which then allows it to spread. If food is stocked up near the fan, cold air can't get past it, and the fan itself could develop frost to the point where it freezes and stops working entirely. This can be prevented by not overstocking the freezer and by evenly distributing food throughout.

Temperature Setting Too Low
The freezer should have a thermostat that regulates how cold it gets. If the temperature is set at too low of a setting, the freezer kicks into high gear, the air freezes outright and frost quickly builds up. Adjusting the thermostat to a higher temperature or level can counteract this problem, but you may need to de-thaw the freezer to eliminate the frost that has already built up inside.

Keeping the Fridge Door Open
Many people keep their fridge door open for extended periods of time while they examine the contents inside to see what they want to eat. This can contribute to frost buildup in the freezer, because the fridge is taking in a lot of warm air during this process and the fan pushes it up into the freezer. The moisture in that air is then quickly frozen, and ice can build up substantially as a result. The longer the fridge door is held open, the more likely this can occur, so the best solution is to only keep the fridge open for short intervals and then to not open the door again for a while.
Hope this tips will help you. : )

Hi,

Thank you for contacting fixya.com.

Check the condenser under the refrigerator is clogged with lint. Make sure that the condenser fan underneath the fridge is running properly. You can get to it through the back. Check the coils on the rear of the refrigerator and make sure they are clean and dust free. Also check the back wall or floor of the freezer section for frost. Check the evaporator fan to see if it is running. Check the condenser coils under the unit for blockage from dust. Check the condenser fan under the unit to see if it is running. If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost terminator, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. Also check the freezer to ensure it isn't over loaded with food stuff, reason being air must flow freely threw out the entire refrigerator in order for the thermostat to work correctly.

Defrost the freezer by disconnecting the power to the refrigerator and letting it sit for at least 24 hours with both the doors open to allow the frost to melt completely but it will build up again in 1-2 weeks and start the warming up again.

Hello,

Let's start by diagnosing the freezer;

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food.

I hope this helps.

Regards.

Have you noticed more frost in the freezer than usual? It sounds like you may have moisture building up and freezing around evaporator fan. The fan blade hitting ice will cause the buzzing until it stops it completely or the evaporator clogs with frost and blocks airflow. If you have frost on food in freezer, check the door seals and make sure nothing is keeping doors from closing completely if you release them about 6" from cabinet.

Yes that is a proplem...when ever that compressor is running that fan motor should be running too.. also you evapurator fan motor should be running also
