Kenmore 795 bottom freezer - cont.

Hello,

The ice maker fan is located in the freezer and is part of the Grille Assembly ( LG part Name) Which is the removable back panel in the freezer. If you have an error code on the display such as ER/IF the fan is not rotating due to failure or ice accumulation in the fan blade. If you have no error code and the ice maker is not producing ice 2 things to check are...1. On the bottom of the ice maker there is a Test Button. Press and hold the button and the ice maker should rotate, Dump ice cubes and refill with water. If the ice maker does not cycle replace the ice maker. 2. Check freezer temperature. Freezer Temperature must be below 15 degrees to make ice. Ideally freezer temp should be 0 Degrees. If you have warm temps in the freezer there may be a sealed system issue preventing proper cooling.

Hope this helps.
Mike

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.

Hello Danie;

My name is Peter. I am a retired field service refrigeration technician.

The normal setting for a freezer is -2 to +2 degrees F., and the normal setting for the fresh food section is +35 to +40 degrees F.

You only have one source of cooling and that is your freezer. With the settings that you have, you are asking your unit to do what it is not designed to do.

The ice maker is struggling because if it is a cast steel ice cube mold, the heater beneath it is not designed for the current to break the ice cubes free @ -18 degrees F., or if you have a plastic flex ice cube mold it is too ridged to flex enough to break the ice cubes free. Normally your ice maker should dump 8-10 times in a 24 hour period.

A note on food storage. Make sure you do not overload your freezer of fresh food section to the point where food product extends beyond the edge of the shelves.

Error codes are brand (and often model) specific. "de" likely indicates something in the defrost process, especially on G.E. Check for ice build-up in the freezer cooling coil. The control board would be suspect, but must be checked to confirm the precise fault.

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.

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!

The error codes are listed in the service manual (p. 32) at the address below:
LFX25960 Service Manual

"Er dH" seems to be a defroster issue.

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.

The freezer compartment may not be as cold as previously. Check the condition of the door seal of the freezer compartment or try setting a colder temperature. The Ice Maker has a Thermostat that senses cube temperature and controls a heater switch which turns the ice tray heater on to free the cubes for dump. The problem could be that this thermostat, if failing, is delaying the cycle.
