lg lfxs24623s Freezer not getting to temperature

Hello,

I have an lg freezer with the model in the title. It appears to me that the freezer is not getting to the proper temperature. I have it set at -1. When checking the temperature with a crude thermometer it is averaging out between 27-30 degrees. The fridge appears to be cooling to the proper temperature, and the ice maker also appears that it is working. There are also some small drips of water coming out of the front french doors. So far I have pulled the refrigerator out, and cleaned the condenser coils with an appliance brush and waited about 3 hours and I am not seeing a temperature change in either direction. The fan, and condenser appear to be running. I also checked the seals around the door and I do not see any very apparent lack of seal. Any assistance on places to look to resolve would be greatly appreciated.

Thank you!

Hi,

Here's the troubleshooting section from the service manual.

Check if there are any error codes shown when checking for errors.

As there is only the one evaporator unit in the refrigerator in the freezer compartment, the refrigerator compartment temp "appears" to be normal because as the freezer is not getting down to its set operating temp. the refrigerator compartment is showing the same temp as the freezer compartment or near enough anyway.

Is the compressor running continually trying to cool the freezer down to its set operating temp of 0°F?

If not it may be a faulty freezer sensor informing the control board that the temperature is correct even though it isn't. Go to p.24 in the manual linked above to see how to test the sensor.

If it is then it may be a leak of refrigerant in the sealed system or a faulty compressor.

Check for any traces of oil on or under the condenser coils and the compressor which may indicate a leak. There is a special oil mixed in with the refrigerant to help lubricate the compressor and if there is a leak, the refrigerant will escape to the air undetected but the oil may leave a trace.

If nothing is obvious the high and suction pressures in the sealed system will have to be checked. Depending on your location you may have to have a licensed refrigerator repairer do this, due to the environmental regulations regarding the handling of refrigerant gases. Besides which they have the equipment to do this safely and correctly.

My sister had the same problem with her GE. The added symptom was that the freezer coils were icing up. After carefully examining the freezer seal, since that is usually the cause of something like this, I could not determine a problem. The seal appeared to be in full contact all the way around.

I decided to remove the seal as it was easy to do. When I did I discovered that the door was hitting a drawer in the freezer and wasn't closing as far as I expected it to.

I removed the drawer, replaced the seal and all ran well.

This was after a GE tech had replaced the control board and returned a 2nd time, with no solution.

Moral, the seal can be open without being visibly open. Something inside may be holding it from fully closing.

If the coils ice up the freezer will not get to a temp below the ice temp (about 32°F). Since the refer temp should be about 35°F it will be fine. You can't see the ice on the coils unless you remove the covers. My brother-in-law did that 3-4 times and defrosted it with a hair dryer. It worked for a week or so until the coils iced up again. The ice is caused by the humid room temp air that the seals are letting leak in. This is not an uncommon problem and should be ruled out b4 looking at more serious not so common issues.
