LG LRSC26940ST Defrost Heater Problem

My LG LRSC26940ST Refrigerator displayed error code Er dh. Problem with the defrost heater. Need to replace but need some help with making sure I order the right part. I looked at Repair Clinic and found the defrost heater part but I don't see it anywhere in the Frige. Looked in the inner back of the freezer where the exploded view showed, but can't locate where the part would be. What part do I need and where is it located? Please help!

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

SOURCE: 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

SOURCE: I a LG 22860sw refrigerator ERROR CODE DH

The main Pcb as well as the defrost thermistor are in the circuit as well.
The thermister is attached to the evaporator with wire ties and connects to the roof of the freezer behind the fan assy.

I have seen the thermister connector pull out of the connector at the top of the freezer beacuse the wires were to tight. Remove some of the wire ties and reinstall the connector.

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.

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.

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