Question about Refrigerators

3 Answers

Recently noticed diminished cooling effect in the refrigerator section (side by side model). We also noticed a "snow" build-up in the freezer section. Investigating the problem I noticed a burned out light bulb. It was replaced with a good one.It did not come up. I also noticed an odd pop sound during my investigation. I do not have any documentation and the Google is not helping to locate one. Thanks fo help Milan

    Hello Sir,
    here is an update.

    Right after commiting my cry for help to cyberspace I investigated the problem further. I noticed:
    - compressor not running and hot. I could not hold my hand on the top for long.
    - fan working fine
    - outside coils not clogged (cleaned some time ago).
    - I gave the compressor a litlle "knock" with a rubber mallet and unplugged and plugged the
    fridge. I could hear the compressor "humming".

    After receiving your response I checked:
    - Fan in freezer section works (I knew it before). The fan was replaced aprox. 3 years ago
    whe the freezer quit. It was difficult to find the part.
    - Temperature setting: freezer on recommended value "B"
    fridge on 4;recomended setting is 3. We use the recomended
    settings. I only put it higher for test.
    - Found the opening for cold air from the freezer section(close to "meat" drawer) blocked by
    ice- removed.
    - Found a second cold air passage between the freezer and fridge part blocked with ice
    - cleaned.
    - Defrost timer: could not find it. Defrosted "manually"
    - Temperature control : not tested yet.
    With the remedy applied I am waiting to see whether the situation improves. It looks like the
    refrigerator may work.

    Q 1: Are you aware of any circuit diagram or manual for this type of refrigerator ?

    With Regards and many Thanks

    Milan Imrisek

    PS: I'll inform you about the situation in a few hours.

    From the context I realized that the refrigerator model did not get in to my entry though it was in a header of the web page. Here is what is on the sticker:
    Model: YRS 20DKXDW00
    Ser.#: SE 3021046
    Type: C 20SSA 95
    Manf.Date: 07-95
    Whirpool Corp.; Benton Harbor, Mich.
    I would like to have any documentation about it (or at least a link to the source).

    To conclude the case: Our fridge is back in operation and my wife is much happier today.

    My thanks go to everyone who responded to my entry.

    With Gratitude

I read through what you have done so far. By defrosting you have put the problem off. With no knowledge of your brand I can't say for sure but in side by side units you will find a heater in between the halves of the fridge and freezer or sometimes in the back of the unit. This is for defrosting the coils. Most times you can find a schematic on the back of one of the back covers on the unit.
Also if the unit was frozen up the ice may have damaged the wiring for the light. If you put a new bulb in and it didn't work I would check this also.

Hi there,

Between the two sides there is usually a port with a motorized shutter which allows cold ait from the freezer to enter the fridge side. It's located near the top and may have a foam border.

There is also usually a fan attached to force the exchange.

Sometimes if the humidity is high, the freezer builds up ice. When enough builds up, the fan stops, then the shutters freeze.

If the servo motor that moves the shutters engages while it is frozen, the linkage can break, leaving it in whatever position i=t was in at the time.

Step one is defrost.
Step two see if such a port exists on your model and if so, see if it works.

If not, try to manually slide the ports open until the module can be replaced.

Wish I could be more detailed, but without the make and model, theres a lot of conjecture.

Best regards

Due to various reasons this problem could occur:

1)First you have to resolve for the cause of the issue.
First Check the back wall or floor of the freezer section for frost.The Freezer(evaporator) fan is running?.This fan problem is very hard to detect.
The DC motor for the fan wears out the RPM's are effected.It gives the illusion that it is running fine,but it don't have enough force to supply air circulation for both the freezer
and the refrigerator See weather the condenser coil for
blockage from dust and the condenser fan is running.
2)Check the temperature setting.
Set it to max and min and check for any changes you can see in the system.
2)The the freezer vents cold air to the refrigerator.Occasionally the vent can become clogged with ice, food or other debris. Locate the vent and clear it. To remove ice, use a hair dryer set to "low". Using the high setting may cause damage to the components or interior of the refrigerator.
3)Defrost timer:Usually the defrost timer could solve this issue.It may be located below or back of the refrigerator.Some times it may be located in the side to for side refrigerator.Locate the timer and rotate the clutch head screw clockwise until you hear one audible click. That puts the system into defrost mode. If the system restarts after 30-35 minutes.Then there is no problem with Defrost timer.
4)Test the temperature control
With the ohm meter you can test it.If it does not show any reading this is the defective one you have to relplace this soon.

Openings in the door:
Keep a paper in the door and close and check it are you able to pull it out easily.The
electrostatic force should not allow you easily pull the paper.If it so you have to replace the hinges or the hinges out of line or the cabinet distorted.
post a comment for further assistance.

For time being Solution:Switch off your Refrigerator for 4-8 hours and melt the "snow" build-up in the freezer section.Use hair dryer to melt it quickly.Now switch on the system and see the cooling effect.It will be increased.The snow" build-up in the freezer section will not allow the cool air to flow into the Refrigerator.There will be valve in the backside through which cool air flows.

post a comment for further assistance.
Thank you for using fixya have a nice day:-)

    I the compressor in making clicking sound then its not big problem,If it is making very loud humming noise.The coil inside the compressor has worn out.You have to change the coil.Take it to the service center ask him to change only the compressor coil.They will say u have to change the full compressor.The exact reason inside the compressor making humming noise is the coil is the defective one.But i believe you can run Refrigerator the cooling will get increased because you cleared the clog.I need to have the model of your Refrigerator and Refrigerator name because the wiring diagram differs from Refrigerator to Refrigerator.In many modern Refrigerator defrost timer is along with temperature control board.So you have to check weather temperature control board is working or not.

    Thank you for your comments hope you will resolve the problem
    Have a nice day sir/madam

My Model #gts22wcp fridge stopped getting cold. freeezer works great. Only blows cold air into fridge if freezer door is open.

Possibly a problem with the defrost system. If the cooling coils behind the freezer wall start to build up too much frost or snow, the air flow to the refrigerator section gets blocked first. So the freezer still works but the fresh food section starts to get warm . As the frost continues to build up, in time the freezer section will only get as cold as the fresh food section should. There are 3 main parts to the defrost system. You could have a burned out defrost heater, a bad defrost timer, or a bad defrost termination thermostat. The heater is located directly under the cooling coils in the freezer. The termination thermostat is a silver round disk clipped to the top of the same cooling coils, and the timer in located in the control panel in the fresh food section.

Refrigerator side doesn't feel cool but the freezer side is cold for a Maytag refrigerator model # MZD2766GE

Is there ice build-up in the back of the freezer? If so take the panel off the back of the freezer section inside the freezer and replace the heating element.

Refrig not cooling Freezer has frost build up on coils

Frost on the coils won't allow air to pass to the fresh food section, thus resulting in insufficient cooling. To eliminate this problem, you will have to get a new adaptive defrost timer ( small board ), and a defrost heater assembly.

Samsung side by side

Check for snow on the back wall of the freezer compartment, Air to cool the refrigerator is supplied from the freezer section. If the coil is frozen over the air circulation becomes retarded and the refrigerator suffers. Snow on the back wall indicates a defrost problem.

Samsung RS22NJSH Freezer Fault

hi there the fault you have is very common these units do automaticaly defrost to clear ice from the evaporator the problem that they have is when the defrost heater comes on it overheats and blows the safety thermal fuse resulting in the evaporator getting more and more iced up, to cure the fault you will need to replace the thermal fuse which has now been modified and the defrost sensor.

hope this is of some help

GE Side by Side stopped cooling

This sounds like the defrost heater is bad or dead. The refrigerator will not cool because frost is building up on the evaporator coils in the freezer section and the fan can no longer push air past the coils. You will find that the freezer will build up with frost.
If you are brave enough, remove the cover in the freezer and you will see the coils are completely covered with frost (ICE). At this point with the refrigerator unplugged ( remove food). get a hair dryer or heat gun and melt all the frost. You will notice a heating element ( looks like a tubed light) -element will looked burnt out.
Replacing it at this point is easy. Before you start though, try to get the manual for your system and call around for a local appliance parts store to see if the part is readily available.
