My ge profile arctic is not cooling enough even with the temperature control at max for both freezer and refrigerator.

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.

The most common cause for this condition is a problem with the defrost system. If the refrigerator freezer is cold but the refrigerator is warm, the evaporator fan motor might have failed. ... If the freezer is cold but refrigerator is warm the air damper control might be stuck closed or broken
The Evaporator Coils are Frosted Over
If the freezer is cold but the refrigerator is warm and the evaporator coils are frosted over, there may be a defrost system problem. Several times a day the defrost heater assembly turns on for a few minutes to melt away any frost or ice that may have accumulated on the evaporator coils. If the defrost heater assembly has burned out, or the defrost thermostat or defrost control have failed the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling. The most common cause for this condition is a problem with the defrost system.
Evaporator Fan Motor
If the refrigerator freezer is cold but the refrigerator is warm, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. These are the coils that get cold. A small fan and motor is mounted near the coils. This fan and motor - called the evaporator fan and motor, draws air over the evaporator coils and circulates it throughout the freezer and refrigerator. If the fan fails, the freezer or refrigerator will get much warmer than usual.
Damper Control Assembly
If the freezer is cold but refrigerator is warm the air damper control might be stuck closed or broken. The air damper control is either an automatic or manually operated door which opens and closes to let more or less cold air into the refrigerator compartment. If it doesn't open properly it won't let enough cold air into the refrigerator. If the evaporator fan is running, the damper door is open and no air is coming out. The evaporator may be frosted up caused by a defrost problem.
Thermistor
If the freezer is cold but the refrigerator is warm 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's freezer is cold but the refrigerator is warm 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.
Defrost Thermostat
If the refrigerator freezer is cold but the refrigerator is warm, the defrost thermostat might be defective. Several times a day the defrost heater turns on for a few minutes to melt away any frost that may have accumulated on the evaporator coils. In order for this to work, the defrost thermostat has to sense that the coils are cold enough. If the coils are cold enough the defrost heater will turn on. If the thermostat is defective it may not be able to sense the temperature of the coils and then won't turn on the defrost heater. If the defrost heater doesn't turn on, the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling to the freezer or refrigerator. The defrost thermostat can be checked for continuity. It should have continuity when it reaches the low temperature of its operating range.
Main Control Board
If the refrigerator's freezer is cold but the refrigerator is warm the main control board might be defective. This is not common. The cause of this problem is almost always in the defrost components.

Refrigerator: Freezer not cold enough. Defrost system problems, dirty condenser coils, fan failures, leaky door gaskets or control problems can lead to your freezer not getting cold enough. ... The frost buildup blocks cooling air paths through the evaporator so the freezer doesn't cool well.

Freezer is cold but refrigerator is warm

1. Evaporator coils are frosted over

If your issue is that the freezer is cold but the refrigerator is not as cold as it should be, the first step is to check the defrost system for problems. A key indicator in determining if perhaps you have a refrigeration defrost problem is visible frost on the evaporator coils. If your unit has frost you will need to check your defrost heater assembly, the defrost control, and the evaporator fan motor for a malfunction. Replace any erroneous parts as necessary.

1. Damper

If your issue is that the freezer is cold but the refrigerator is not as cold as it should be, the damper door could be broken or jammed. The damper is a door that opens and closes to allow cool air to flow from the freezer into the refrigerator unit, and if it fails to operate correctly, not enough cold air will enter the refrigerator to keep it cold. The damper can be replaced if it is no longer operating properly.

1. Thermistor

If your issue is that the freezer is cold but the refrigerator is not as cold as it should be, the thermistor connected to the control board might be defective. The thermistor is a sensor that examines the temperature inside the unit. If the part is defective, the refrigerator could not cool properly.

1. Temperature control board

If your issue is that the freezer is cold but the refrigerator is not as cold as it should be, the temperature control board could be at fault. The temperature control board distributes voltage to the fan motors and compressor to keep them functioning. This board is very often misdiagnosed as the culpable cause and it is recommended to proceed with the troubleshooting process of elimination prior to replacing this part.

1. Defrost thermostat

Another issue that can cause your freezer to be cold while the refrigerator is not as cold as it should be is the defrost thermostat. In order for the defrost heater to activate to melt away any excessive frosting on the evaporator coils, the defrost thermostat must sense that the temperature is cold enough to activate the defrost heater. Without this continuous cycle, the frost will excessively build up on the coils and prevent proper air flow inside the unit. The defrost thermostat can be checked for continuity with an ohm meter; if it's not present, the thermostat will need to be replaced.

1. Main control board

A possible cause for a freezer that's cold but refrigerator that's not as cold as it should be is the main control board. The main control board acts as a "brain" for the unit, controlling the defrost cycle, compressor, and run time. However, it is an uncommon cause for this issue. This board is very often misdiagnosed as the culpable cause and it is recommended to proceed with the troubleshooting process of elimination prior to replacing this part.

If the refrigerator is not defrosting the defrost heater assembly might be burned out. Several times a day the defrost heater assembly turns on for a few minutes to melt away any frost that may have accumulated on the freezer or refrigerator evaporator coils. If it fails, frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling. The defrost heater can be checked for continuity. If it doesn't have continuity it should be replaced.
Next chance is the defrost thermostat might be defective. This signals that the coils are cold enough. If the coils are cold enough the defrost heater will turn on. If the thermostat is defective it may not be able to sense the temperature of the coils and then won't turn on the defrost heater and create the same problem you mentioned. It can be tested for continuity when it reaches the low temperature of its operating range.
You may also have a bad main control board that tells everything to work when it is supposed to such as telling the defrost heaters to activate or interpret the thermostat message that it is time to defrost.

Good luck!

Start by checking the thermistor. It is located in the freezer by the coils. At room temperature(75 dgrs F.), your thermistor should read 5.1k ohms. Here is the part to order in case it is bad.

Hello,

A refrigerator not cold enough is a hassle, because you are at risk of spoiling the foods you store in there. Most often, this problem is caused by something easy to fix.
1. Faulty Door Gaskets

The door gaskets in a refrigerator ensure a sealed closure every time you shut the door. Torn or loose gaskets on the door of the refrigerator can result in a leak in the cold air. As a result, the refrigerator is warmer. Repetitive and frequent opening and closing of the refrigerator is also a possible cause, because the warm air from outside replaces the cold air in the refrigerator every time you open it.
2. Dirty Condenser Coils

Dirty condenser coils can result in improper functioning of the refrigerator. These coils are located on the back or the underside of refrigerators. If you find this to be the cause of the problem, unplug the refrigerator before you attempt any cleaning.
3. Frost-free Feature not Working

If the frost-free feature fails, it causes a buildup of frost around the evaporator coils in the freezer. This causes a malfunctioning of the evaporator fan that blows cold air around. The fan can also be damaged if it hits the frost.
4. Faulty or Incorrect Temperature Control

A faulty thermostat can lead to a refrigerator that is not maintaining the desired coldness. Check for this problem and also ensure that the temperature is set to the correct level. Normally, refrigerators are set to a temperature of about 0°C, whereas the freezer sections are around -17°C.
5. Inadequate Air Flow inside Refrigerator

A refrigerator that is loaded with too many food items can fail to maintain an adequate level of coolness across all the items kept in it. The surface items tend to be colder, and the items underneath do not become as cold. A refrigerator that has very few items in it can also fail to function efficiently. Try to ensure that your refrigerator has enough food in it at all times, but is not so loaded that the air flow gets constricted.
6. Vents between Freezer and Refrigerator Clogged

The vents between the freezer and refrigerating section blow cold air from the freezer across to the refrigerator. If these vents are clogged with ice, the air is blocked and the refrigerator does not cool down. If this is the case, you can unplug the refrigerator, wait for the ice to melt and then connect it back to the power supply.
7. Faulty Door Switch

The door switch is found on the bottom of refrigerator doors. It turns off the light in the refrigerator and resumes cooling action when you close the door. If this switch is not functioning properly, the refrigerator will not be cold and it will also be affected by the heat of the interior light.
8. Refrigerant Leak

A refrigerant leak is very unlikely. This problem can cause malfunctioning of your refrigerator. If you suspect this to be the cause, contact a service technician.

Good luck in solving the problem....

Refrigerator or freezer is not cold enough check this part:

* Check the temperature setting
* Assure that there is enough room for air flow in the refrigerator or freezer
* Check for air flow restrictions in vents
* Test the temperature control
* Clean the condensor coils
* Check the door seals
* Test the door switch
* Test defrost heater
* Test defrost timer
* Test evaporator fan
* Check for a clogged drain tube
* Check for refrigerant leak

I believe that because defrost is done by the mother control board this is why this is happening the part of the board that controls defrost is malfunctioning and the only way to resolve the problem is to replace the mother board part number WR55X10656 You can find the replacement board at these places below.

Is there anything obstructing the fan area, ice build up ? It is normal for your freezer to get warm if evap fan is not working, it is essential for it to work :) A defrost cycle should kick on a timer or as needed (adaptive) and there should not be excessive frost buildup that it blocks your evap fan. I would have suggested you unplug your refrigerator for about 10 minutes and see if that resets your control board - if not, then you will need service - either replacing motor assembly or a faulty control board.
