Question about LG LRBN20510WW Bottom Freezer Refrigerator

1 Answer

ER code on interior lcd show up & shuts off the fridge

LG fridge 2-3 yrs old top fridge bottom pull out freezer. Fan motor starts running loud and soon enough ER shows up on the display and the unit shuts down. fixed so far by blowing a hair dryer on the back wall of the freezer which gets rid of frost and poof works fine for a couple of weeks then its a do over. could it be related to my ice maker leaking a bit when it fills - i imagine a small puddle of water on the frz'r interior floor contributes to the frost build up but not sure if related or part of the problem. Tech came out months ago - said I needed a new condenser- $1000 or something - he also said a new cond'sr was not guaranteed to fix the issue - i sent him packing 2 seconds later - i was also told to cool the condenser using wet bath towels & a fan, did it, but results are the same as the blow dryer "solution" works for awhile (weeks) then ER comes back & it shuts off. i have no idea how hot cond'sr should be - i can lay my hand on it w/out melting my hand but it's temp is uncomfortable afer a bit. Its not a power issue, surge, brownout, or fluctuation - i changed outlets and put a batt back up unit in, didnt matter ER showed up again. SO ............any ideas?

Condensers really are hot or warm.the freezing/icing is caused of blocked air passages or blocked air circulation.resetting the defrost timer sometimes do the trick.have you check your defrost timer?also, the bi-metal disk inside the evaporator or freezer is malfunctioning.this bi-metal controls the fan blower.if its open the fan is not functioning or vice-versa.have a tech to check this two parts.if not then clogging/holes in the tubes or worst motor problem. but first try the defrost timer by rotating the its knob.

LG GR-B206GTQA Fridge Freezer ER CF Error Code


The fan is almost certainly run by a sensor in the condenser. If it doesn't get hot enough, the fan doesn't run. Sounds like short of gas. Try wiring the fan to the compressor live and see if it runs all the time then.

Error code er ff.how do i fix this? freezer is still freezing but fridge is warm.


The error code appears when there is an abnormality of BLDC FAN Motor for Freezer. It circulates cold air from the freezer to the fridge to allow cooling. Check the motor wiring harness for poor connections. If the motor is not working at all, you need to replace it.
To remove the fan and motor assembly:
  1. Remove the freezer shelf. (If your refrigerator has an
    icemaker, remove the icemaker first).
  2. Remove the plastic guide for slides on left side by
    unscrewing phillips head screws.
  3. Remove the grille by removing one screw and pulling the
    grille forward.
  4. Remove the Fan Motor assembly by loosening 2 screws
    and disassembling the shroud.
  5. Pull out the fan and separate the Fan Motor and Bracket.
  6. Replace fan motor assembly in reverse order.

FF error code


The ER-FF problem that you have is: ERROR -FAN FREEZER so it means that you have a problem with maybe the fan motor or if it's a bottom mount freezer maybe ice built up on the fan motor so it's blockin the fan motor.
Hope i helped u a little bit ! :)

I ahve a Kenmore Elite side by side refrigerator with watre and ice on the front and freezer below..there is a message Er IF on the dispaly and it will not make ice..this unit is 1 1/2 yrs old..the freezer...


This is an error code for the icemaker fan motor.
If the control does not see a signal coming back from the fan motor you will get this error code.
Please see the image below from the service manual that explains the ER IF error code.

http://media.fotki.com/1_p,wkbwtkdqbqkgrkkxgtqsskgwtqkq,vi/ktfgsrbbdxktrrwffdr/1/1303472/5961857/image18067img-or.jpg

The ER IF code indicates a failure of the icing fan.

You may notice slower ice production but the other fans should be okay.

You can select the ultra ice option and see if the fan toggles on.

The fan or the control is bad.

My fridge shows the following error codes er and ff


I called a local authorized dealer and when the service man came he knew right away what the problem was and fixed it in about 1/2 an hour. The bottom freezer was iced up very badly but the fan was working fine. He cleared the ice away, and said that the fridge needed to be raised on the front as the water during the defrost cycle was not all draining away and over time the ice just kept getting bigger and bigger and finally it jammmed the fan and it could not work properly any more and the LG fans have a safety feature which shuts the fan down. This service man was very knowledgable.

Fan in the freezer stop working ater a while


You may have a serious issue with the wiring harness inside the refrigerator.  You will need to have the technician come back out and check the continuity of the wires leading from the control board to the fan checked out.  If there is no continuity, it is not repairable.
