Refrigerator warm, Freezer cold

Is there any frost buildup on the rear panel inside the freezer? If so you have a defrost problem of a bad defrost heater, defrost thermostat, or defrost timer/ control board. If no frost then you probably have a clogged defrost drain. Remove the rear panel to access drain hole.

Hello

Seems like you have a bad thermostat,you should Unplug the appliance and take off the light cover to gain access to the thermostat.

Look carefully at the thermostat and you'll see the terminals are numbered,write down these numbers and go get a replacement part for your refrigerator.

return air ducts from the freezer may be iced up, unplug unit and use a hair dryer to defrost. The ducts will be behind the rear panel, but just let the hot air circulate for a couple of hours to really defrost it
good luck

your evaporator coil in the rear area behind the freezer back panel is frozen over with ice and the coil can no longer deliver cold air due to ice blocking the air flow from the evaporator fan,remove this rear panel,defrost it with a hair dryer,check the defrost heating coil for continuity,they go bad regularly,if not the heater coil under the evaporator coil,it may be the defrost timer in the refrigerator section of the unit that powers the defrost coil that needs replacement

Usually when the freezer is still giving cold but the frig is not receiving cold you have an ice build-up on the cold (evaporator) coil that is hidden behind the rear panel of the freezer compartment. If you push on this panel, you usually will hear a cruntch sound (this tells you there is ice/frost on the coil). There are 3 components that affect this problem: defrost timer, defrost stat, defrost heat coil. In other words, something is not working to remove the frost from the coil and it is building-up day after day (takes about 5-7 days to become full (blocked). When this happens, no air can move over the coil to take the cold away and blow it throughout the frig or freezer compartments.
To access the defrost coil or stat, you have to ren move the back panel (in the freezer) and remove all the ice with a hair dryer only or let the door open all day and allow it to melt. DO NOT PUSH OR PRY OR CHOP WITH ANY TOOL OR YOU WILL BE GARRANTEED TO PUNCTURE A HOLE IN THE COIL AND YOU ARE REALLY SCREWED. The time is either: under the front of the whole refrigerator, or in the frig compartment (towards the back or attached to the ceiling of frig compartment). If you have some experience with electrical parts, you can test to see which part is at fault. Good Luck. Macgivor

You should not have to manually defrost. Your auto defrost system is not working. Check the timer usuall in the frig compartment near the thermostat ( a small hole, use a screwdrive flat tip 1/4" to rotate the timer till it clicks starting the defrost cycle) check freezer in 10-15 min should be defrosted if not you will need to check the heater and thermostat located behind the rear or bottom panel of the freezer.

The defrost timer could be under the box in the front behind kick panel or in the rear by the compressor.

I believe part number W10135899 Defrost Control Board is defective. The board is located inside the fresh food section and behind the control panel. Near the temperature controls. Look at the rear wall of the freezer. If a layer of ice is forming on the rear wall of your freezer then it also is forming behind the rear panel of the freezer and restricting air flow. The Defrost Control Board is the most likely reason then there are 2 more things to have a look at. That is the defrost heater and the defrost thermostat. Would not be a bad time to manually defrost your freezer so you can bring temperatures down and replace the part. Unplug refrigerator, remove the rear panel inside back of freezer and defrost the evaporator coils with a hair dryer Or you can leave a bucket of hat water setting inside the freezer compartment with door shut for a while. Let me know what you find, again most like problem is the Defrost Control Board, Thanks, Sea Breeze

Rick,

This is the generic answer. Use the hair dryer (below) and reset the defrost (look for instructions from Sea Breeze)

Most of these units work with the freezer providing all of the cooling and a thermostat in the refrigerator section controlling a fan in the freezer (where the fan directs cold air from the freezer section to the refrigerator section via a duct in the back).

Look at the rear area of the refirgerator and locate a vent. This vent receives cold air from the freezer to the refirgerator. If you feel cold air coming out of this vent, then there may be no problem, just wait a few hours and recheck the refrigerator temperature.

Look at the rear area of the freezer and locate a vent. This vent provides cold air from the freezer to the refirgerator. Shine a bright light into this vent. You should see fan blades (possibly black plastic). If there is ice on the blades, then you have a defrost problem, and look to other posts on this site for how to manually defrost (or reset the automatic defrost). If the fan blades are rotating, then there is probably a blockage in the duct. Direct a hair dryer (warm setting) through the rear freezer vent and check to see if there is very warm air flowing out of the refrigerator vent (which indicates that the duct is not blocked). While using the hair dryer, you may be able to see the fan blades rotating.

If you do not feel warm air flowing out of the refrigerator vent, then run the hair dryer for a few minutes. (this was my problem, I saw no moisture drip from the vent, which led me to believe that it was more of a dry ice buildup, or that the ice was evaporated (desublimed to be technical).

If there is air flow and no ice buildup on the fan, then reset the automatic defrost. If this is not your solution, either the thermostat or the fan motor is the problem.

You have a defrost issue and needs to be serviced by a qualified LG technician.  The freezer fan motor is blocked by a large chunk of ice behind the rear panel of the freezer section.  You will need to remove the rear panel to get access to the fan and get rid of the ice.  This will get your refrigerator working again but this problem will return.  You will need to have your control board replaced.

change the adaptive defrost board located in the upper right corner of refrig under the panel. remove panel by pulling on panel towards you from the finger holes in the rear. remove two 1/4 inch screws and two phillips screws. defrost manually with hair dryer behind panel in freezer.
