Er if code comes on. I have let it defrost for 4 hours. Code disappears and then reappears. I would like to know how to fix it.

Hi, here are the error codes and meanings for your Refrigerator

Error Code, All Error Codes will have an ER on the left side, followed by the error on the right:
Er IF - Icemaker Fan Error - This can be caused by frostaccumulation on or around the icemaker fan. Unplug the unit for 3-4hours to allow this to melt off. If error code persists, call CustomerService.
Er FF - Freezer Fan Error - This can be caused by frost accumulationon or around the freezer fan. Unplug the unit for 3-4 hours to allowthis to melt off. If error code persists, call Customer Service.
For remaining error codes, try unplugging the unit for a couple ofminutes to reset the unit. If the error code persists, call CustomerService
Er FS - Freezer Sensor Error
Er rS - Refrigerator Sensor Error
Er ds - Defrost Sensor Error
Er dH - Defrost Heater Error
Er CF - Cooling Motor Error
Er CO - Communications Error


Thank you.

The Er DH error code indicates the temperature sensor on the evaporator coil did not reach 50 degrees within one hour.
This would indicate the control board did put the refrigerator through a defrost cycle.

This problem could be caused by a defective relay on the control board, a defective defrost heater, a broken wire to the heater, or a stopped up drain on the defrost pan causing ice to form on the evaporator coil.

Before replacing the control board, someone should remove the food from the freezer, remove the freezer drawer, and remove the evaporator cover to expose the evaporator coil, heater, and defrost sensor.
The voltage to the defrost heater should be 120 volts ac.
The defrost heater is part of the evaporator coil and is not replaceable as a separate part.

You can test the operation of the defrost system by pressing "Ultra Ice" and "colder freezer temp" for 3 seconds.
The first time you press and hold the buttons the board will test the compressor, fan, and open the damper.

All displays should be on.


The second time you press and hold the buttons the board will test the compressor, fan, and close the damper.

The third time you press and hold the buttons, the board will turn the compressor and fan off and turn the defrost heater on for around 25 minutes. This would let you know if the defrost system is working.

ER IF indicates that the ice maker fan is not working. The fan is probably frozen. Remove the fan duct and housing at the back of the freezer and you may be able to defrost the ice in the fan enclosure. It will not defrost sufficiently by turning the freezer off for 2 to 4 hours as LG suggests. The fan may have frozen because of high humidity or because the defrost cycle is not working. If your unit is still under warranty LG should fix it by replacing the fan, duct panel and control board with new ones that have been re-engineered to prevent this problem.

Check for current flow through the defrost heater. If no current then replace the heater. If heater is OK check thermistor for correct operation. From service manual chart (their words not mine): ER DH is Poor defrosting. Indicates: Even though it is passed 1 hour since then
Defrosting , if Defrosting
sensor is not over 8°
Remarks: Temperature fuse Disconnection,Heater
disconnection, DRAIN Jam,
Poor Relay for Heater

it the def t-stat, def. thermistor, or def. fuse whatever lg decides to call it this week that is causing your issue
