I have error code ER dH. Unplug and then replug and the error comes back. Ice looks good and cooling and freezing temps are normal.

    I think for Trio model number 795.75553400, the parts list is #610C and the part number is 6500JB2002P

  • cbass300 Feb 25, 2009

    Replacing the sensor(s) did remove the 'er dH'. It is one connection with two senors. I did need to remove the upper shelves in the freezer along with the ice maker. Remove the screw underneath the ice maker left wall (push up on the ice maker to remove), the screw in the middle of the back panel and the screw on the left of the back panel underneath the water. Disconnect the plug for the ice maker. Gently pull the back panel forward, I used the vents and wiggled. On the right side of the evaporator is the sensor and plug. Cut the plactic ties and replace old sensor with new one.

Error Code - erdh


Kenmore and LG 795 Series. Model 795.77556600 but most models use the same repair. Controller Part # 6615JB2005H

To Verify correct part. Check part number for your model number at www.searspartsdirect.com


Don't be intimidated by this repair... The 'erdh' error code indicates - error defrost heater. Replacing the controller is EASY. The difficult part is removing everything in the freezer section to access the evaporator coil but hang in there and stay with it. You will not hurt anything if you use common sense.


The new part (defrost controller) is relatively inexpensive ranging $10 - $14. Here in the SouthWest I used Appliance Parts Depot for a $10 part cost. Don't forget to have 3-4 small wire ties to secure the defrost heater, defrost sensor and wires.


It would help to write down a few notes of some of the particulars during disassembly.


I had the same ERDH 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.


(See Diagram Image) I accessed it by removing the freezer door, all components inside the freezer, including the slide rails / tracks mounted on the sides of the freezer. Be careful when removing the rear white panel because an evaporator fan is mounted on the back of it and plugs into the back left side of the freezer compartment. You just saved yourself about $375 or more.

Stay With It & Good Luck!

Er dh means the refrigs computer is not sensing a defrost cycle (dh means defrost heater) most common problem is a bad defrost sensor located on the evaporator behind  the plastic cover in the back of the freezer compartment. your refrig will continue to cool for about 1 week unless you get this fixed then the evaporator coil will ice over and have to be defrosted manually.

this is an easy part to replace yourself and you can purchase the part thru sears.com or any of the other parts distributors on the net. you will need a complete model number from the unit to be sure and secure the correct part.
Thanks for using FixYa peyton...

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

I have a Kenmore Elite Refrigerator, Model No. 795.77573600. The ice and water dispenser give the error message Er 1F. In searching online it appears that this problem is related to the ice compartment...
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.

Problems for Refrig. Kenmore Elite
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.

Control panel shows "Er dH"
The “er dh” code means a problem with the defrost cycle. It is triggered when the defrost sensor does not reach 46 degrees F within 2 hours of the defrost cycle starting. If indeed the defroster is not working, the evaporator (in the bottom of the fridge in the freezer compartment and behind a plastic cover) will eventually ice up completely, blocking the flow of cold air to the upper compartment. Use a thermometer to check the upper compartment to verify that no or little cool air is reaching it.  If the evaporator is iced up, the defrost cycle is not working. Quick fix to restore operation to the upper compartment: tape over all vent holes in the upper section to keep that cool while you work below. There are about 6-7 vent opens in the back wall and two large one on the floor of upper compartment. Remove freezer door, drawers, slide rails and pull back the plastic cover (2 screws hold it in place, one in the center and one behind the ice maker) at the rear of the freezer section to expose the evaporator. Spray hot water on the ice accumulation on the evaporator (it looks like a radiator) to melt it (remembering to sop up what flows to the drain pan at the rear). The entire operation can be done in about 30 minutes (most time is used for removing ice and sopping up water from the drain pan). All should be ok for 3-4 days depending on humidity before the evaporator ices up again.  In the meantime, order a replacement control board. You can view this by removing a panel w/ 3 screws at the rear left of the refrigerator. This panel controls all refrigerator functions, including defrost. Most likely, the integrated relay for the defrost cycle failed. Swapping out panels is a 10 minute job. Panels cost about $116 incl shipping from repairclinc.com. Shipping is about a week.  You can find a free service manual on line that will help to identify all parts and is particularly useful for removing doors and trays so you can get at the evaporator.  All in all, the customer service is useless. The fridge however is very easy to work on and amazingly simple. The replacement board has a slightly different relay for the defrost heater, so LG may have realized a problem existed with the original. It is also possible that electrical surges damaged the relay.  In any case, 10 minutes and $116 seems pretty minor to have the fridge back to new condition. Good luck.
