LG Refrigerator Defrost Error ER DH-- Defrost fuse

Hi Marine,
Thanks for your help. My LG freezer works normally now, but it still turns to the same error status after several hours. I have to unplug and re-plug it again and again. Is the fuse the one mounted in the wall of freezer compartment?
If I replace it with a new one (either LG or other generic), the issue should be fixed, right?
Thanks,
Steve

The fuse is in the fz compartment behind the evap cover panel once you get the panel off it will be at the top right-hand corner wedged between the evap coils

Problems for Refrig. Kenmore Elite


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.

LG code ER DH, Defrost Heater or Thermistor?


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

That stands for "error defrost heater"
Even though the refrigerator has gone through a defrost cycle, if a temp sensor does not reach a set temp within an hour, that error will display. You may have a bad defrost heater, defrost relay, thermal fuse, blocked defrost drain,..... something wrong with the defrost system anyway.

Where is this fuse located on the LG refrigerator is displaying a ER DH code error


Hi. You have an Error Defrost Heater. Its taking too long for the heater sensor to open the circuit during defrost. You normally replace the heater, heater sensor and circuit board(motherboard) located on the back of the refrigerator in this situation. Check your mollex plugs and make sure they are connected tightly at the evaporator coil area. Sometimes they come loose. I reccommend replacing the heater and heater sensor located top right on the evaporator coil. This should take care of the problem. Need parts see me on ebay as user, themackshack. Good luck, Mack

That stands for a defrost heater problem. Usually it's the defrost detect circuit that has a blown thermal fuse.
