Hi Jildaw,

With the help of this and other sites I was able to fix my error fairly easily ..I wrote a step -by-step HERE...Hope it helps some.. Was alot cheaper then a service call !

Good luck!

This error code has something to do with a defrost sensor and happened after an extended power outage. I unplugged the refrig and it reset itself!

check your service manual and see what it say about err dh

yOU DON'T SAY WHAT THE MESSAGE IS. EITHER WAY IF THERE IS A ERROR CODE USUALLY ONE OF THE FANS ARE NOT RUNNING OR THERE IS A DEFROST PROBLEM.

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.

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

Do you have the ER DH error message showing? If so, it is a failed senser, an $11.99 part that many of us are having trouble with.

I faced the same problem for Kenmore elite Trio Model # 795.77543600 bottom freezer refrigerator. The issue as pointed out by Medeer on fixya.com, turned out to be the part called component assembly, part number 6615JB2005H. I got this replaced yesterday but for 4 hours I did not notice any cooling... so I thought it did not work.... but then in the morning I notice that the issue has been resolved, the refrigerator is cold and there is no eR dH error message. Thanks to all who shared on this site.

Either you have accidently left the door open at some time in the last few weeks or you have a faulty defrost sensor, initially turn off defrost freezer over night with doors open, turn on following day, unit should start to work within 12 to 24hrs, other wise replace defrost sensor but still deforst.
