LG LRFD25850ST gives ER CO code on door

Hello I have a LG fridge that at first gave me a 8's across the board and every led light on board was lit. If I unplugged it and plugged it back in, it would reset and act normal. Now I am getting a code on the display that says ER CO. When it displays this everything locks up. Need I say during this whole issue, the fridge keeps cooling like normal. Now when I unplug it and plug it back in, it shows the fridge temp setting and freezer temp setting, but no room temp. Then about 25 seconds later it goes back to the same ER CO on the display. Both boards have been replaced and now I don't know where to go with it. Can anybody steer me into the right direction? Thanks.

    My fridge also has the ER CO error code after a power surge. In this case I am assuming the control board will have to be replaced. This is a good time to put a surge protector on all your electronics

Good call Cooltech! My new LG "open box" deal from Best Buy must have been delivered once before. I hauled it home, plugged it in and Er CO was on the display. The doors must have been removed to get through tight spaces, exposing the bundle of wires and connectors under the left hinge cover. One wire had been repaired with a crimp lug, wire cut too short, and the crimp was no good. I soldered the connection and added 2" of wire so it wouldn't be stressed. Works!

There is a communications error between the control board and the display board.  Check the connector located on the top hinge cover.  Remove the hinge cover and check to make sure the connector is tightly secured.

What is wrong when I receive error code Er rF


Hello Anonymous!
Error code Er rF is an :Abnormality of BLDC FAN Motor for Freezer.
  • The freezer fan motor may be Defective.
  • Unplug the fridge for about 30 minutes and plug it back in, if the code appear again within 24 Hr , the Main Board might be defective too.
  • Check if the freezer fan is blowing normally, then the Main board has a problem.
  • If not, the Fan Motor is defective or both.
  • I would change the Fan first then the Main PCB
Good Luck,
JP

I have an LG fridge display giving me ER F1 code. i can unplug the fridge and plug it back in and the display resets for about 2 minutes and the the code comes back?


The ER 1F code usually means that there is a problem with the ice compartment fan, the ice maker motor or one of the control boards (the one for the ice maker or the main control unit). You can try resetting the refrigerator by leaving it unplugged for a day. Next check for ice build up on the fan that is blocking it from turning. Usually, if the fan hasn't been turning, you will have to at minimum replace the motor. It will burn out trying to force the fan to turn.

Sears Parts Direct has a diagram of the LFX23961SW case parts here: http://www.searspartsdirect.com/lg-refrigerator-parts/model-LFX23961SW/3204/0161000/K0810254/00001.html . The fan motor is part 405G.

I hope this helps.

Error codes Er rF


Hello, you have to down load the LG smart refrigerator app.
once you do this then you open the right door of the Refrigerator then press lock on the fridges control panel.... Turn on your smart app and place near the top right of the fridge with the door still open, you will hear a series of beeps and then your phone will tell you what the Diagnose is for the error code.

Not working, ER and CO in spots for temp. French


ER CO is an indication of a communication error between the display board and the main board. Has this unit had a board replaced recently? If so, one of the multi pin plugs may have not gotten connected firmly, or an incorrect board may have been installed. The problem has nothing to do with the dust.

LG Model LFX25960 has error code ER 1F


Turn off the switch for the icemaker, then flip the circuit breaker to off for a few seconds and turn it back on. The display should remain lit and operable, but you won't have an icemaker. See service manual pg. 32: http://136.166.4.200/contents/Fridge/LFX25960/LFX25960_Service_Manual.pdf
