SOURCE: 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

SOURCE: LG refrigerator error code

Had the same problem + a weird noise, which turned out to be ice build up on the blower fan. Unplugged overnight and then opened the lower back panel. There is a small fan that blows over some small coils at the bottom of the box. There is also a drip pan that should be "full" of water. I sponged out the drip pan, put the panel back on and then plugged back in. Works great.

ER FF is a freezer fan error. Basically the mainboard is not receiving a feedback signal from the freezer fan motor within 65 seconds. When this happens the error code will come up and then none of the buttons will work.

You can clear out the error code by unplugging and plugging the machine back in. The error code will come back if the problem persists. Check around the freezer fan motor fan blades to see if ice buildup is interfering with the operation. Clearing out this ice may fix the issue.

If the problem comes back, then the fan motor may be getting ready to go out or the unit may not be defrosting properly.

Hope this helps, please rate my solution.

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

The fridge is not cooling. Error ER DH showing on door. Freezer works fine. Was told that the PCB board is to be replaced as well as the defrost module. Cost will be approx $600. Can you advise o


The "Er dH," also known as the Defrost Heater Error message, is displayed when the unit fails to reach 46? F within 2 hours of beginning its defrost cycle. This may be an indication of the defrost heater having broken or the temperature fuse having been pulled out of its slot. Contact customer service if the problem persists after having attempted a system reset.
Quick Fix
  • Unplug the refrigerator for 30 seconds and then plug it back in. Doing this will reset all the codes. Sometimes an error appears by fault. If it does not appear again after restarting, then the refrigerator is fine. If the code appears again, then there is a problem with the defroster.
Defroster Problem
  • The error code itself means that the defroster mode has failed. This means that the defrost mechanism cannot reach 46 degrees Fahrenheit within two hours to defrost ice in the freezer properly. Unplug the refrigerator and move all the items that can spoil into a backup fridge or freezer.
Repair
  • Look in the back top of the freezer. Use a screwdriver to remove the ice maker machine that blocks the back defrost panel. Remove the two side screws and pull away the plastic cover guard. Check the wire. If it is unplugged, then secure it to see if that is the problem. If the plug is connected, then remove it to check for more problems. Look for any faulted wires on the defroster. If it appears that the wires are fine, you need to replace the defroster panel. Contact your local LG dealer for the specific part number

probably heating element in freezer is broken.
Remove power and defrost. Remove wall panels in back of freezer to Check heater element behind panels With ohm meter should read 20 ohms or less.

Refrigerator displaying error "ER FF".


Error Code "Er FF" indicates a problem with the unit's freezer fan.

The freezer fan controls the temperature in the freezer. The source of this error is most likely ice buildup. As with the Er IF error, allowing the unit to thaw should resolve the issue.

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.

Hope this helps.

Help....kenmore trio refrigerator, error message "er co"


The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.
