Question about Refrigerators

2 Answers

General Electric Eterna series ESS25CGMC CC freezer coil keeps frosting over with ice crystals. Result is freezer stops freezing, refrig. stops cooling. I have defrosted it 2 times, and afterwards it works great for about 2 weeks, then it frosts over again! Internal Fan is running fine, I have cleaned compressor coils and fan is running fine there too! Door seals are in great shape and you can feel a definite vacuum on the doors seals when you open either door.

    Omhs reading between blue wire and orange wire as indicated was 22.8 omhns....remove heater, gave 21.8 Ohmns......is this suffice=ient for the proper operation of the unit? Or.....what do I check now. Thanks

  • jnwalker1954 Aug 24, 2010

    Thanks I have checked the continuity across the blue J9 wire(removed) and the orange wire on the J7 board 22.8 Ohmns.....also removde heater and checked it = 21.8 Ohmns. The heater coil looks all green and dirty however. Would you recommend just replacing both?
    Or is this a good reading? Definitely not an open circuit.....

  • jnwalker1954 Aug 28, 2010

    Thanks...I just replaced the heater and the little thermostat that mounts on the coils and everything is fine now! I figured for less than $80.00 might as well give it a shot. The heater looked pretty bad. It was all discolored and looked light it was just burned out.

Inwalker1954,

It sounds like your defrost element or the control is bad. To check the defrost coil you will need to unplug the frig and unload the freezer. If you have enough ice chests everything should be good for several hours. Remove the cover from the evaporator coil in the freezer. Usually below the coil is the defrost coil. It is a small heating element which turns on periodically by the thermostat to remove any moisture from the coil. It does this when the unit is not calling for cooling.

Remove at least one wire from the coil and check it with a DVM set to ohms. It should read low resistance but not no resistance and certainly not high resistance. If it checks bad you will need to install a new one.

If it checks good you will need to order a new thermostat control. This may be on the refrigerator side. All parts can be ordered from http://www.repairclinic.com which also has very good people to help you determine the exact part you need as well as good how to videos.

This should get your unit working properly.

Thanks for using FixYa and for the great rating!!

You have a problem with the defrost circuit of your refrigerator. The defrost circuit is periodically activated to defrost the evaporator coils. This circuit consists of the controller board, the defrost heater and defrost thermostat. The controller board is located in the back of the refrig just above the compressor behind an access panel on the right side. The defrost heater and thermostat is mounted on the coil. The heater and thermostat are connected in series so, if either component fails, the heater does not turn on. Most likely the problem is caused because of a break in the heater connection.

This can be checked with the freezer still cold and using an ohmmeter. To do this, unplug the refrigerator, and pull the access panel from the back of the machine. Behind the panel will be the control board. On the lower left side of the board should be a blue wire connected to the J9 connector. Remove the J9 connector and connect the blue wire and the orange wire on the J7 connector to the ohm meter (J7 is located on the bottom of the board). The meter should read around 30 ohms. If it reads infinity, then the heater/thermostat is opened.

To get to the heater/thermostat, you will need to empty the freezer and remove the entire back panel to access the coil. The heater will be mounted on the bottom of the coil. The heater is attached to the defrost thermostat through a wire and the thermostat is mounted on the top of the coil. Check for any visible breaks in the wiring. Most likely is that the heater is burned out. The heater and thermostat can be bought at any appliance supply house or online at repairclinic.com.

Let me know if something is not clear or if you need more help by leaving a comment. Thanks.

    23 ohms seems normal to me. With your refrigerator, you can put it into self diagnostic mode. What I want you to do is to put the refrigerator into diagnostic mode then turn on the defrost mode and see if the heater turns on.

    Plug the blue wire back into the control board, but leave the cover off. Plug your refrigerator back in.

     

    To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display can be illuminated by pressing an adjacent temperature adjustment button. When both displays are illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all 4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and freezer displays will indicate that the refrigerator is in Self Diagnostic mode.



    Set the defrost mode Set the Freezer display to 1 and the Refrigerator Display to 4. This should turn on the heater if the thermostat is still cold.

    Set your meter to read AC voltage and check the voltage between the orange wire J7 and the defrost terminal J9 and verify that you see 120VAC.

    If get 120VAC then the heater needs to be replaced.

    If you don't then you need to run a self test on the module itself by set Set the Freezer display to 0 and the Refrigerator Display to 7 This will check the thermistors. Thermistor test results:

    • P = Pass

    • 0 = Failed

    • S = Short to 5 VDC

    • B = Bad amplifier

    If they show up as P then the problem might be with the main board or thermistors.

    If it finds anything else then the thermistor needs to be troubleshot.

    I will attach a link to a service manual
    http://appliancejunk.com/ge/refrigerator...

    Let me know if you need any additional help. Thanks

    I just sent you instructions how to put your refrig in self diagnostic mode. Depending on that outcome will determine whether the heater needs to be replaced. Thanks.

  • jnwalker1954 Aug 24, 2010

    This Refrig does not have the control panel with tempurature control buttons that you refer to. There are no lights. It has 2 dials in the refrigerato sider. 1 for frige and 1 for freezer. The exterior of the freezer door has water / ice/ crushed ice, and water filter indicators only.

  • jnwalker1954 Aug 25, 2010

    Thanks great, But after reading the guide, I can tell you that this is not my refrigerator. I ahve the ESSX25XGMC CCmodel. So Like I was telling you, I do not have the electronic temp controls. I have the dials inside the refrige door at the top of the unit. Is there another publication on this unit. Can you even place it in diagnostic mode? Does it use the front dipensing panel to perform this diagnostic?? Any information is helpful. Thanks again!

  • Stephen Lam Aug 26, 2010

    Sorry for not getting back to you sooner. You won't be able to put your refrigerator into self diagnostic mode since it is not equiped with a display. If you want to check the defrost heater and thermostat, you can jumper the blue wire to a brown hot wire to see if the heater turn on.



    But before you try that, check the evaporator thermistor, to see if it is reading the temperature properly. To do this, remove the JI connector off the controller board and attach your ohm meter leads to J1 pin 4 and pin 5. If your evaporator is still ice covered, the ohm meter should read aroun 16.3k ohms. If it is off by more than 5% you will need to replace this thermistor.



    If the thermistor is ok, then replace the controller board.

Refrigerator is cold, freezer not freezing


Amana refrig have 2 main problems . 1 is the defrost bimetal ( 1" cylinder at the top right on the freezer coils with 2 wires ) and the other is a refrigerant leak where the copper tubing joins the aluminum tubing at the freezer coils ( evaporator coils ) . If your freezer fan is not working and you have frost on the freezer coils then replace the bimetal as this also controls the defrost heater ( defrost thermostat ) . If you have no frost on the coils ( for both checks , you will have to remove the inside rear freezer panel , maybe 12 screws ) , then a refrigerant leak has happened and the best solution would be to replace the refrig .

My model is ARB 1914 CC nine years old.


your "damper vent door" located between the refrigerator and freezer compartments is frozen open or the cold adjustment contron in the refrige is bad and not powering the door as you change the temp set for the refrige and leaving it open,if the door is frozen from ice/frost just de-ice it with a hair dryer and then set the temp adjust and see if it opens and closes with any adjustment

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

Freezer compartment has frost buildup


This can be caused by the drain hole below freezer coil being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost. Possible defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer.

ICEMAKER FROSTING UP


Try to take some ice from the dispenser. Remove the glass and open the freezer door to look down inside the dispenser chute and see if the trap door has re-closed. If it remains open warm, humid air will enter the ice bucket and gradually freeze the cubes together. Trap door remaining open is generally caused by a rusted electrical coil which pulls the door open electrically then sticks, unable to re-close. Coil is located behind the panel that operates the dispenser. Relatively easily accessible.

Frost in Freeze


Hi Frezer Frost.
It sounds like your defrost circuit in the refrigerator has gone south. This melts the ice off of the cooling coil in the freezer section every 8 - 10 hours of run time.
If you are old enough to remember the manual defrost refrigerators, that is why you had to defrost them occasionally. The ice layer on the coil acts as an insulator, preventing the coil from working properly.
