Your system uses R-134a refrigerant.

If the compressor is running but it's not cooling, you probably have a refrigerant leak or possibly a restriction in your evaporator.

Unfortunately, refrigerant leaks are not DIY friendly, so my advise would be to call a competent repairman.

I have no cold air in my refrigerator or Freezer. It defrosted everything.


Condenser Coils are Dirty
If the refrigerator is not cold enough the condenser coils may be dirty. The condenser is like a radiator and must stay clean in order to dissipate the heat which was removed from the inside of the refrigerator. As the coils get dirtier the refrigerator becomes less efficient, which makes it work harder to cool down. If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the inside of the refrigerator to the proper temperature.
Evaporator Fan Motor
If the refrigerator is not cold enough, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. The refrigerator may have one or more evaporator fan motor(s) depending on the model and evaporator locations. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment. The freezer may still get cold.
Condenser Fan Motor
If the refrigerator is not cold enough there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back. Pull the refrigerator out from the wall and remove the access panel to access it.
Start Relay
If the refrigerator is not cold enough, the start relay may be defective. The start relay is a small device mounted to the side of the compressor. It provides power to the run winding along with the start winding for a split second at start-up to help get the compressor started. If the start relay is defective the compressor may run intermittently or not at all and the refrigerator will not get cold enough. The start relay should be replaced if defective.
Temperature Control Thermostat
If the refrigerator does not get cold enough the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem.
Start Capacitor
If the refrigerator isn't cold enough the compressor might be having difficulty starting. The start capacitor serves as a battery to give the compressor a little boost during start-up. If the start capacitor is burned out the compressor might not be able to start and run as often as it should. Test the start capacitor first with a capacitance meter, they don't fail often. If it's defective, replace it.
Thermistor
If the refrigerator is not cold enough the thermistor might be defective. The thermistor is a sensor which monitors the air temperature. It is connected to the control board. If the thermistor is defective the refrigerator does not cool or may cool continuously.
Temperature Control Board
If the refrigerator is not cold enough the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.
Compressor
If the refrigerator is not cold enough, the compressor might be defective. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. There are several other components which are more likely to be defective if the compressor doesn't work. If the compressor itself is defective a licensed professional will need to replace it.
Main Control Board
If the refrigerator is not cold enough the main control board might be defective. This is not common. Check the defrost system, cooling fans, and cooling controls first.

Freezer goes -9 and fridge goes to 40 I have set it to 0 for freezer and 34 for fridge it changes on its own


Depends on type of refrigerator freezer you have, but you need to realize that the evaporator (cooling coils) are in the freezer, and the cold air produced in the freezer is then circulated via an evaporator fan into the refrigerator section. The thermostat the cycles the compressor motor is located in the refrigerator, and the compressor will run until the temperature reaches the desired level in the refrigerator. On most units, the freezer temperature setting simply regulates how much cold air is circulated into the refrigerator.

What you are describing is that the freezer is working fine (almost too good), but the air is not properly getting to the refrigerator area. Several things can be causing restricted airflow, including a faulty evaporator fan, icing of the evaporator coils because of a malfunction in the automatic defrost system. Check to see if there is frost or ice build up in the back or bottom of the freezer. The proper temperatures should be around 0 F for the freezer and 38-40 degrees F for the refrigerator.

My freezer is not blowing cold out. I hear the compressor running but its not getting cold


most likely bad evaporator fan motor located behind the wall in the freezer,when you open the freezer door you should hear the fan blowing in the freezer unless it's in defrost,if you don't hear it check it in 45 minutes if still no fan it's bad.

REFRIGERATOR NOT GETTING COLD


. Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. If the relay is ok there is a compressor problem or low freon it it don't start

Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm




Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

Not all refrigerators are insulated the same and not all condensers are in the same place. Your cold control is monitoring the temperature of the refrigerator section and is designed to turn off the compressor to keep things from freezing in that section. If it stays cold long enough outside in your garage the cold control thinks its cold enough and won't turn the compressor on. A makeshift closet to hold a little heat the unit generates will probably help.
