Freezer part doesn't freeze door was part open for hours

It almost certainly needs a new thermistor, which is the electronic thermostat sensor.

Check to see that the evaporator is not covered with layer of ice. The latter serves as an insulator and prevents freezer temps from going down to about zero degrees. If the defrost heater/timer is defective that will certainly be a cause. Since the freezer air is not cold enough to freeze, then the refrigerator temps are also high. Using a digital thermometer will confirm this.

Leaking door gaskets can also be responsible for higher internal temps

1) Press the "Express Freezing" key and the "Colder" key of the Freezer Temp function at the same time and hold for 3 seconds. The refrigerator will enter Test Mode 1. Test Mode 1 allows diagnostic function of the compressor and freezer fan, stepping damper open, defrosting heater off and display LEDs all on.

2) Touch the "Express Freezing" key and the "Colder" key of the Freezer Temp function at the same time while in Test Mode 1 and hold for 3 seconds. The refrigerator will enter Test Mode 2. Test Mode 2 allows diagnostic operation of the compressor and freezer fan, stepping damper close and defrosting heater off.

3) Press the "Express Freezing" key as well as the "Colder" key of the Freezer Temp function together while in Test Mode 2 and hold for 3 seconds. The refrigerator will go into Test Mode 3. Test Mode 3 allows diagnostic operation on the compressor and freezer fan off, stepping damper close and defrosting heater on.

4) Press the "Express Freezing" key and the "Colder" key of the Freezer Temp function at the same time while in Test Mode 3 and maintain for 3 seconds. The refrigerator will reset to the state prior to entering test mode.

5) Unplug the •Lg refrigerator from the wall outlet, then plug it back in to reset the appliance after coming out of test mode.

Please pay careful attention to step 5

Checked Freezer Fan is working. Also checked defrost Fuse in freezer.
To checked freezer fan is working or not open freezer door press Door Switch and checked Cold air is coming from duct or not.

Empty the freezer & fridge, turn the unit off, leave the door open for 24 hours, to let all the ice melt off the coils, then turn it back on & make SURE the doors are closed well.... You will know that this was the problem in about 3 hours, when the freezer is back at normal temp.....

Be sure to put some towels in front of the unit, and also inside the freezer when it is off, as you may have more water (melted ice) than the drain pan can handle.....

Hello there:

If every thing has been defrosted it should take about 6 to 8 hrs to fully freeze again now that is also depending on how you have the freezer temp set i would set the temp so that it gets the coldest that it can than after the food has frozen than reset it back to you setting that you had before ok
Hope this is very helpful for you
Best regards mike

You will have to remove the inside rear freezer panel .The # 4 thermistor is bad . This tells the main control board , the temp of the coils , if they need defrosted , when they are thru defrosting . This thermistor is the 1 " long , torpedo looking piece , clipped on the top left of the coils , with 2 white wires going to it . Part number WR55X10025 . It would be advisable to also replace the # 5 thermistor , located at the bottom of the freezer , slightly in front of the drain , also with 2 white wires going to it , slid into a housing . This thermistor , is the freezer thermistor , which tells the control board , the freezer temp and when to cycle off due to temp setting .

Make sure freezer door seal is completely sealed. No gaps, Also, if you are up to the challange, you will need to remove the freezer panel, test thermometer, thermostat, for voltage and resistance. Also check that the flapper that seprates freezer from fridge air.; Is not frozen.

in leaving the door open you may have over heated the compressor and not it is not pumping enough freon anymore
