Question about Kenmore 24.8 cu. ft. TRIO Bottom Freezer Refrigerator

Kenmore Elite Refrigerator error er dh

The refrigerator portion is not really cooling like it used to and the error message of "er dh" shows on the display for a couple of weeks now. It will only go away for a few minutes if you unplug it and plug it back in and then it will return. I've read online that the defrost sensor may need to be replaced. Sears on the phone doesn't seem to know what I'm talking about or locate the part that I would need. Any help? Is the defrost sensor called something else? If I order and try to replace this part, is it hard to replace and will it most likely fix the problem? I just just got my Kenmore Elite Trio delivered yesterday and I had to call for service 5 minutes after that. 1) The water/ ice maker does not work but there is water in the filter. 2) The lights does not work. 3) Now I get this "er dh) message on the lcd panel. I should have done some kind of research on this unit but impulse buying got a hold of me. I bought a lemon!!!

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.

Freezer working fine but refrigerator not cooling


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.

Kenmore Elite Refrigerator error er dh


Great advice from medeer, I had the same ER DH error code, and my refrigerator began to warm up. I replaced the defrost thermostat assembly part # 6615JB2005H which is located inside the freezer, on the right side behind the white plastic panel. I accessed it by removing the freezer door, all components inside the freezer, and the tracks mounted on the sides of the freezer. Be careful when removing the white panel because a fan is mounted to the left side of the white panel and plugs into the back left side of the freezer compartment.
Found the green technical data sheets under the refrigerator in a small plastic bag near the front.
My refrigerator is 20 months old, just a few months past the warrentee,

Kenmore 795.7731 Fridge warm;freezer cold - Error er dH


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.
