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.

I have a Kenmore model 795 77563600 refrig side


This is an error code for the icemaker fan motor.
If the control does not see a signal coming back from the fan motor you will get this error code.
Please see the image below from the service manual that explains the ER IF error code.

http://media.fotki.com/1_p,wkbwtkdqbqkgrkkxgtqsskgwtqkq,vi/ktfgsrbbdxktrrwffdr/1/1303472/5961857/image18067img-or.jpg

The ER IF code indicates a failure of the icing fan.

You may notice slower ice production but the other fans should be okay.

You can select the ultra ice option and see if the fan toggles on.

The fan or the control is bad.

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,
