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

This is the 1st (and easiest) step to take:

1. Turn power off to the refrigerator (i.e. unplug)
2. Leave OFF for at least two minutes to allow the CPU to reset
3. Turn power back on (plug in)

This solves 98% of these problems with the Kenmore Elites.

Step two would be to call service.

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.

SOURCE: error code

THE ERROR CODE MEANS THAT YOU HAVE A DEFROST PROBLEM. THERE IS A PART THAT SITS ON THE EVAPORATOR COIL TOP RIGHT SIDE CALLED A CONTROLLER, COULD BE BAD. IF YOU UNPLUG THE REF THE MAIN BOARD WILL RESET AND ERASE THE CODE. WHEN IT DOSEN'T DEFROST THE CODE WILL COME BACK UP.
