LG Refrigerator Working But Freezer Not FreezingLG Refrigerator Freezer Not Freezing

I have a problem with my LG refrigerator, the freezer is not functioning but the fridge still works. The LG refrigerator was cold but my freezer wasn’t getting cold enough. I researched this issue and found a solution and fixed it. This specific repair took 45 minutes to fix the freezer.

LG refrigerator works but freezer does not?

First thing to do to rule out other issues is unplug it for 24 hours to see if the coil inside is frozen. Yes you will need another freezer to put your food in when doing this. Also, check all seals, vents to be sure they are not blocked, level the refrigerator, and set the temperature controls correctly.

Problem: LG refrigerator has freezer that will not freeze. The freezer started to thaw and everything in it was thrown away. I noticed the ice maker had stopped making any ice and everything in the freezer was soft. The freezer is not freezing anything but the refrigerator section is working just fine. We changed the freezer temperature numbers from high to low but had no effect. I turning the thermostat all the way down and then back up again for a few hours, but that’s not doing anything to get the freezer working.

I tried the simple thing first by defrosting it, to be sure there was no problem with the automatic self-defrosting. I also unplugged it for 24 hours to see if the coil inside was frozen. This did not solve the problem. However, if you have this issue, try the following fix if you live in a dusty environment and you have not cleaned out the pan at the back of your refrigerator.

Solution: Removed back panel of refrigerator and was able to get at the drain hose for the pan. Some other pans of dusty water was sitting on the bottom shelf. There was dust completely covering the area. I used a shop-vac and cleaned out all the dust and dirt. The very bottom hose was down in the dirty water. That was cleaned of all dirt and dust to troubleshoot the problem. To be sure the line was clear, I shot compressed air into both the freezer and refrigerator, which checked for airflow on the other side and air came out.

Dust was the problem. The coils under the refrigerator/freezer is how the fridge sheds heat. If the coils or other components of the refrigerator are covered in dust or dirt, then the heat cannot be released or something may be clogged or blocked. Clean the coils well by vacuuming the refrigerator/freezer coils as the condenser fan is in that location.

HINT: If both the freezer and refrigerator are both warm, it is usually a sign of a dirty condenser coil under the unit where the compressor and fan is. Clean and vacuum it and it should begin to work properly.

If applicable on your LG refrigerator freezer: The linear compressor uses vent doors to regulate cold & cool, so there may be a problem with the venting.

What else can cause an LG freezer to not work?

Dirty Condenser Coils Issue:

If the condenser coils are located inside the freezer walls, you do not need to clean them. Whether the condenser coils are easily accessed from behind or under the unit, you should clean them every 6-12 months. If the condenser coils are dirty, they will not be able to dissipate heat effectively, which can drastically reduce the cooling capacity of your freezer. Clean the condenser coils if they are dirty or have not been cleaned in a while.

Evaporator Fan Motor Issue:

The evaporator fan motor circulates air drawn from the freezer’s coils over the evaporator and throughout the freezer. If the evaporator fan motor is not running, your freezer will NOT freeze. Check the evaporator fan motor by opening the freezer door and pressing the freezer door switch. If the door switch is activated and the evaporator fan motor won’t run, replace the evaporator fan motor to get the freezer to operate properly again.

Start Relay Issue:

The start relay gives power to the fridge/freezer compressor. If the start relay does not work then the compressor will not run. When the fridge/freezer compressor will not turn on or run properly your freezer will not be cold. Unplug the freezer, remove the start relay from the compressor to find out if the start relay is faulty. Get a multi-meter and test the start relay. Test for continuity between the start and run terminals. If the relay has no continuity, remove and replace.

Evaporator Coils Frozen Issue:

Problem with the defrost system? The defrost heater turns on multiple times daily to melt frost that has built up on the freezer evaporator coils. Frost will accumulate on the evaporator coils and the coils will frost over If the defrost heater does not turn on. To troubleshoot if the defrost heater is faulty, use a multi-meter and check for continuity. If no continuity remove and replace the defrost heater.
