Question about Refrigerators

1 Answer

GE TFX22ZA refrigerator freezer is not cold enough, 38 C at the coldest setting. The fresh food side is at 42 C. I cleaned the radiator on the bottom. That did not make any difference. What should I try next? Change the thermostat? Where is it located? Please give me some hint, appreciated. Thanks

    Hi Ginko,



    Thanks for your answer to my question.

    Please tell me where is the thermostat or the temperature sensor as I asked. From the 255 pictures I could not tell where is the part I am looking for. May be you can help me to narrow search a little or just tell me.

    The fresh food compartment is working, (42 C). I think the compressor is working.
    The fan in the freezer compartment is running all the time. The temperature in the freezer compartment is at 38 C.

    Thanks.

Hi Zyao.

Before changing anything, please try performing a complete defrost. Do this by leaving the unit disconnected from power .

If the unit restarts cooling after defrost, then problem was defrost system or damper (ventilation) system. Those are the most common reasons for insufficient cooling.
In that case if there is a faulty part in the defrost system you will get the problem again in few days or weeks. In that case defrost thermostat, timer, element and fan must be tested. Here an example showing testing on a different model. Testing is the same with your fridge.Part location is different. To locate parts see the link at the bottom of this comment. Here general procedure to test and repair a defrost system: When the fridge is not cooling ...

If the unit does not restart cooling after defrost, then the problem is different. The most common occurrence is probably a defective capacitor. The capacitor is mounted on the compressor. Its function is helping the compressor to kick on and run by ensuring a charge reservoir. The capacitor is less than $20. Check defrost first.

There are more problems that can cause no cooling, but they are not really common. Check the defrost system. If defrost system is OK try replacing run capacitor.

Here all parts and diagrams for this model.

Regards.

Ginko.

    Hi.

    The defrost system is located behind the freezer firewall, which is the back panel in the freezer compartment.

    See defrost system installation descriptions here: Partselect: Installation Instructions

PSC23NSTESS FREEZING VEGTABLES


Side by Side ModelsIf foods, such as fruits and vegetables, in the refrigerator are freezing, it can be caused by several things. First, check the controls. They should be set at "C" and "5" or "5" and "5". The proper fresh food temperature is between 38 and 42 degrees Fahrenheit. The freezer should be between 0 and 8 degrees Fahrenheit.
  • If food in the bottom of the refrigerator is freezing, this could be caused by a refrigerator not having enough food to absorb the cold air.
  • If food in the door is freezing, move the door bins up or down so they are one notch away from freezer vents (Side by Side models only).
  • The fresh food control should be at the normal setting of 5.

First, check the controls. They should be set at "C" and "5" or "5" and "5". The proper fresh food temperature is between 38 and 42 degrees Fahrenehit. The freezer should be between 0 and 8 degrees Fahrenheit.
  • Since the cold air coming into the fresh food section originates in the freezer above, the rear of the top shelf will be the coldest spot in the fresh food area. Avoid placing delicate items that freeze easily on the back half of this shelf.
  • If food is freezing in the produce (fruits and vegetables) or meat pan, it may be that the temperature controls are not set high enough. Since cold air naturally falls, the pans can get too cold if the refrigerator is not running long enough to maintain good air circulation. Adjust both controls up one notch.

Refrigerator inside not getting cold enough. A GE refrigerator side by side.


If it is just the fresh food section and not the freezer. Check out this link to see a GE condenser problem. Make sure to clean that condenser once a year. In most cases when the damper assembly flapper door goes bad in the fresh food section, the fresh food side will start to freeze your food. The next thing I would check is what John is talking about. Pull the freezer back panel off to see if your evaporator coil is frost over. When this happens it will restrict air into the fresh food side(refrigerator side). Click Here to see what a defrost problem looks like.

Freezer is cold but not keeping icecream frozen.


If, the fresh food section is 34- 38 degrees, then the freezer should be cold enough to keep ice cream solid. All of the cooling capability comes from the freezer section. I, personally, would not waste time or money on a ten year old box. Ten years ago it cost $1000, so, the outlay is $100 per year. Dump the old refrigerator and get a new one.

Coils keep freezing up its 4 years old


Iced-over evaporator coils, accompanied by a non-chilled fresh food compartment, happened in my GE side-by-side (model GSS20IEMDWW). For me, the problem was caused by a faulty temp sensor in the fresh food side. That sensor never signalled the computer that the temp in the fresh food side was cool enough, so the compressor ran constantly.

Since the compressor was running constantly, the evaporator coils (back wall of the freezer compartment) eventually iced over (took about a week). Since the fan that draws air over the evaporator coils could no longer move any air (due to the icing), the temperature in the fresh food side got warmer as well.

The fresh food side is chilled through a hole with a motorized door at the top of the dividing wall between compartments which opens when the fresh food side needs cooling. If no air is moving in the freezer compartment, temps in the fresh food compartment climb.

I replaced the temp sensor in the fresh food side and solved the problem for a while.

I bough a pair of thermometers at a kitchen store and put one in the freezer compartment and one in the fresh food compartment so that I could occasionally check to see if it made sense for the compressor to be running (ie, was it really necessary to be trying to cool either compartment, or were they already cold enough).

About six months later I had the coil icing problem again. This time the fresh food side seemed cool enough (according to the thermometer as well as the fact that the flapper door would close, indicating that the computer knew to not try to additionally cool the fresh food side).

The thermometer indicated that the temp in the freezer compartment was cold enough, but the system computer continued to run the compressor. So I replaced both temp sensors in the freezer compartment - which solved the problem again. (My fridge is about seven years old.)

If you are going to replace any of the temp sensors, replace them all under the principle of "if one failed, the rest will soon fail too".

Use a website like www.partselect.com to look up a parts diagram for your fridge and see if you can order just the temp sensors. Other websites (www.repairclinic.com and www.appliancepartsworldwide.com) may also be helpful. I have no affiliation with any of the sites I just mentioned - I'm just posting them as resources.

Refrigerator does not get cold - GE side by side


In my GE side-by-side refrigerator (model number GSS20IEMDWW), there is a motor-controlled flapper door between the freezer and fresh food side. Cold air from the freezer side cools the fresh food side when that flapper door is open.

It is located at the top of the fresh food side on the dividing wall between the fresh food side and the freezer. If this is blocked with something (large left-over container, soft drink bottles, etc), it _may_ be enough to prevent sufficient cooling of the fresh food side.

Of course, there may be a more serious problem with the flapper door mechanism or the control unit that signals the flapper door to open/close.

The vegetable and deli drawers may have a small opening (manually controlled with a wheel or a slider of some sort) that connects those drawers to the freezer side, thus explaining how those areas are still functioning as expected.

Refrigerator does not get cold


In your freezer section, there should be a "control" for the freezer temp. I say "control" because the knob is attached to a flap that only controls airflow the the lower section. If the knob is turned to coldest it will block almost all of the air from getting into your fresh food section.

Ge fridge GSS25LFGww, fridge part freezing food


Hi, Change the controls back to normal settings. Make sure the freezer is getting 0 to 5 above. If the freezer is getting cold enough, try and turn the cold control to 1 and see if the refrigerator shuts off. It sounds like the cold control in not working properly and will need to be replaced. NOTE: The freezer temp has to be right temp or the fresh food side will not work proper.
I hope this helps. Please let me know if I can assist you further.
