I have A LG SXS Fridge. The Freezer is fine the fridge is not cold. I have read that the damper door might be closed. How do I find the damper door?

The part number you need is going to be WR09X10050. This is for the damper assembly, but while you are at it change out part number WR55X10150. this is the part that controls the damper and more than likely if one fails the other will be soon to follow

The problem is damper assembly.In the damper assembly there is a door.This door opens and close with the help of motor.The damper is located between freezer and fridge section.The cold air from freezer section enters to fridge section via this damper door.---------- What repairmen did was proper, but may be that door is not properly got open, it got closed again.Or there is ice got collected between the freezer and freezer section, so this is not letting the cool air to pass from freezer to fridge.----------- ---------- This damper assembly needs to be replaced.Actually this door functions correctly with motor.He open the damper door manually and thought, the cool air will enter the fridge section non stop, but that door is again got closed, by some how.--------- You will have to get the damper assembly part replaced, to get the air flow work properly.------- As the repair man has already ordered the part, otherwise you can get this parts from online sites like www.repairclinic.com or from sears parts direct site.-------- Getting the damper door assembly, replaced will help.Thanks.Helpmech.

Its defrost problem.--------- When you open the freezer door, then ice starts getting defrosted, because outside temperature is warm and due to that inside ice gets bit melted.--------- -------------- The working procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located. ----------- The damper is operated by a motor.Its a complete damper assembly with motor included in it.--The damper has door.Which closes and open with the help of motor.In your case the damper door is blocked by ice, because your refrigerator is not defrosting.But when you open the freezer door, the inside ice gets bit warm and it starts melting and this lets the fridge section get cool.------------------- In this case you will have to manually defrost the ice and inspect, if the problem solves.For manual defrost procedure, click the link below:-------- Click this below for more detail:--- http://technoanswers.blogspot.com/2011/06/refrigerator-is-not-cooling-properly.html ----------- This will help.Thanks.Helpmech.

check the damper vent door for proper opening and closing as if this door is frozen shut or broken and jammed it cant open to let cold air in from freezer it will be behind a plastic grille between the freezer and fridge compartments and you should hear a fan in there running to move cold air too

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

it could be the damper part number WR49X10091,if the damper door isn't closing correctly cold air will just keep coming into the fridge side from the freezer,usually the damper door opens to let the cold air in when the fridge starts warming up and when it gets cold enough the door will close but your damper is stuck open

So long as the fresh food side stays 36-42 degrees you are OK.

Either the damper that the air flows up through is closed or the return air flow vents are blocked with clear ice.

Do you feel the air come out all the way at the top of the duct assembly when the freezer door is opened (but it then stops when the door is closed)?

If so, then it sounds like your return air flow vents are clogged. These are located to the left and right of the duct assembly in the rear/bottom of the refrigerator section. Sometimes you may have to slowly pour hot water into these vents to get the clear ice to thaw. The water should go down into the freezer section behind the evaporator and then out the drain in the back.

If you do not get the air to flow out the top of the duct assembly then the damper is staying shut. This could be either a bad damper in the duct assembly or the main board my not be sending voltage to the damper. Hope this helps.
