My GE refrigerator cools but wont regulate the temperature. Its eather on or off, if I move the thermostat off 0 it comes on but wont turn off even when reaching 28 degrees. I changed the thermostat but no change occurs.

Needs a new thermostat. That temp know you're turning, behind that needs replaced

There are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually the first to be noticed

Walter,
Usually the thermostat control knob is in the refrigerator compartment, and the knob in the freezer controls how much cold air is moved past the damper down into the refrigerator area. All of you cooling is generated in the freezer section and the fan forces is downward. Your thermostat usually has a bulb that senses the temperature that turns the compressor on and off. The factory settings are in the middle of the dial on both areas. Hope this helps!

It doesn't cool

1. Condenser coils

Make sure you dust off the condenser coils to prevent dust build up and overheating due to it overworking. Simply unplug and use a long coil cleaning brush to get rid of debris.

1. Check seals

If your refrigerator door seal is broken, warm air is pushing its way inside the unit, thus causing it to not cool properly. Prevent this from happening by replacing your seal and keeping the cool air inside.

1. Temperature controls

Ensure that your thermostat is set correctly, usually 38-40 degrees Fahrenheit.

1. Defective condenser fan

When this fan is defective, cold air is prevented from flowing through the vents. It may require replacement.

1. Compressor issues

Check if there are clicking sounds coming from the compressor as it tries to start. If there is a clicking, it is one of only two options, either the start capacitor or a bad compressor. A start capacitor is fairly inexpensive whereas a sealed system repair on the compressor is very expensive and often not cost effective. Refrigerator Repair Help Troubleshooting and Parts

After I have been reading up on your unit it appears that the thermostat is not operating correctly. I found this real basic information on installation for your unit. This link I am giving is pretty basic instal schematics. But seems to be something about your thermostat needs to be dialed in or is not working properly.

I hope this helps some. Mike

Check the thermostat bulb in the freezer section. If it is encased in ice defrost for 24hrs. If this does not correct it fit new thermostat, but take care not to damage bulb or tubing it is gas filled.

Hi,

The problem simultaneously is been caused by thermostat in the refrigerator.

The thermostat controls a refrigerator's temperature by sensing temperature changes in the unit and prompting the compressor to turn on and off in response to those changes. The compressor consists of a pump and motor assembly which are housed in a sealed compartment through which the refrigerator cooling liquid travels. When a refrigerator loses its ability to cool evenly and accurately, a faulty thermostat might be the reason. You can test the thermostat along with following basic guidelines in order to help maintain proper temperatures in your refrigerator.


To test if working properly,
Things You'll Need:

• Ohmmeter
• Ice
• Water
• Cup.

First,
Set the ohmmeter to RX1 scale or to the lowest ohm scale.

On the right side of the meter, set the pointer to "zero," making sure the probe ends make contact with each other.

Put one probe on the left side of the thermostat and one on the right side of the thermostat.

The meter should not show a reading if the thermostat is turned off. If a reading appears, replace the thermostat.
When the thermostat is turned on, the meter should indicate "0" ohm or .3 or .2 on a digital readout. If it does not appear as "0" ohm or .3 or .2, replace thermostat.

Turn the thermostat on and place each probe on either side of the thermostat so meter reads "0" ohm or .2 ohm digital. Put water and some ice in the cup. Temperature should be 32 degrees. If, after four minutes, the meter does not reflect infinite or .0000 on the digital meter open circuit, replace the thermostat.

Tips and warnings:

To prevent temperature reduction, avoid putting large quantities of warm foods into refrigerator. Vacuum dusty coils underneath the refrigerator to improve the cooling function of the unit. Ensure that the unit sits four inches from wall to allow cool air to circulate. Avoid opening the refrigerator and freezer doors frequently to preserve low temperatures.

If you must replace the thermostat, be sure to buy the exact model that came with your refrigerator. Always turn the power off and unplug the refrigerator before beginning any repairs.

Take care.

Your thermostat may be broken, I'd check that first.

you may have defrost problem

Keep a thermometer handy. (adjust temperature control knob accordingly)
Periodically monitor temperatures inside your cooler. (adjust as necessary)
Keep the refrigerator door closed as much as possible to avoid temperature fluctuations

The temperature of the refrigerator compartment is
controlled by adjusting/setting the thermostat control
knob, located on the ceiling of the refrigerator
cabinet.
To start the refrigerator, and achieve maximum
cooling quickly;
• Turn the temperature control knob (using a coin
or screwdriver) clockwise to the furthest
(maximum) setting on the darker blue section of
the graduated control dial.
• Allow the refrigerator to run at this setting for 3~4
hours.
• When maximum cooling is achieved, turn back
the temperature control knob setting to the 2:00
o'clock position on the graduated blue control
dial.
• Correct cooling temperature is a key factor to
consider in storing and dispensing draught beer.
• Optimum temperature for serving draught beer is
between 34ºF ~ 38ºF.(1ºC ~ 3ºC)
• To maintain temperatures ranging between
34ºF ~ 38ºF.(1ºC ~ 3ºC) We recommend the
thermostat knob be positioned at the "2:00
o'clock" setting on the graduated blue control dial.
• To turn off the refrigerator, (no cooling) rotate the
control knob to the "0" position.
