Refrigerator No Cool, Freezer Works

This is actually made by Samsung with a GE label. I have replaced the main control board,the FF thermistor, the evap Thermistor each 2 times. I had a tech replace the 3 way valve and blow nitrogen through the lines to make sure there is no restriction. The unit upon power up will intially frost the evap coils, then temp will rise to about 70 and stay. Any Ideas?

    I am not certified on sealed systems, (I do have electronics experience) so I hired a tech ($388) to check the sealed system after I had replaced the boards and thermistors. He had me order the 3-way, changed it and took apart the connection to the evap and blew out the lines and recharged system. Said the capillary and system was clear.

You say " all thermistors check fine " , how did you check them ? Did you check for the 5-8 DC volts at the main control board , for the thermistors ? Did you do the diagnostic check for the thermistors from the control panel ? I'm sure you know there are 5 thermistors , since the refrig has the dual evap . Possibly the # 5 is bad , since it is the freezer temp " controller " , yet if it tells the board it's not cold enough , it still sends refrigerant to the refrig evap . Since the refrig evap has 2 fan motors , can't remember if there is a damper there also . Maybe when the # 3 thermistor is satisfied , it only cuts the fans off , even though refrigerant is still going thru the refrig evap .

The best way to determine what has caused a non defrosting GE electronic control model is to first access the control board. Jump terminals line power to defrost, (J4 and J9). An amp probe should be placed on this jumper wire to determine current draw of the defrost circuit. A three amp draw is what is normal for this circuit. This will eliminate checking behind the evaporator cover to determine a defective heater or over temp device (defrost terminator). Note: This test is only to check the defrost circuit. It does not initiate a defrost cycle. If the unit is in any other cycle than defrost, that cycle will continue to operate as well.


Damper door broken GE arctica:

Affects all 2001 models produced with "M" as the eight letters in the model i.e.: PSS25SGM with serial date code LA4 , MA4 , RA4 , SA4 , TA4 , VA4 , ZA4 & AD4. Freezing happens when damper door breaks leaving the unit with no control over the very cold air entering fresh food compartment from the freezer.

Replace damper door assembly , with new damper door kit WR49X10091.

To verify the damper door is broken , remove the light shield and rear light bulb from the top of the refrigerator. Enter the factory diagnostic mode by pushing all four temperature control buttons at the same time. Perform damper motor test ( FZ 1 , FF 0 ). Press any other button i.e. Custom cool or filter reset to start damper test cycle. Shine flashlight through right hand side opening of light assembly to view movement of damper door. To exit test mode ( FZ 1 , FF 6 ). lf damper door assembly needs to be replaced , pull top two shelves out 2 ". Pull rear tower assembly slightly forward with both hands, move to the left and the right to expose the two screws that secure the duct assembly , also remove both screws that secure the duct to the ceiling. Replace with new damper motor assembly WR49X10091.

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.

Zis480mnc ge monogram built in refer temp varies from 34 to 48 several times a day.


Try replacing that evap thermistor. The diagnostics on thermistors can be wrong. If it is rounded on the end, replace it. There is a damper between the freezer and refrigerator. There may be a refrigerator fan motor in the damper assembly, It could be bad. It could be a bad control board. When you run diagnostics there is one function that checks all the fans.

Hi, i have a ge side by side and the freezer is working great but the frige side is not getting cold , could you tell me what might be wrong. i just put a new motherboard in it.


Pull the refrig out and remove the 8 " x 10 " panel . Behind this panel , is the main control board . Unplug the refrig . Remove the BLUE plug from the board , with 3 larger wires going to it . Looking at the blue plug , the sequence will be wire1,wire2,space,wire3 . Get a short piece of insulated wire , and strip about 1/4 inch from each end . Insert 1 end into wire2 , and the other into wire3 . Plug the refrig back in . After about 3 min , look in the freezer , at the bottom , behind the crisper , look for a red glow . If no red glow , unplug the refrig , and reassemble the plug and cover . This no glow , indicates a shorted defrost heater WR51X10055 . It is also advisable to replace the defrost thermostat ( pt. number WR50X10068 ) when replacing the heater . To access these parts , you will have to remove the inside rear wall of the freezer . The heater , is at the bottom of the coils , held on with 2 screws , and the thermostat , is the 1 " cylinder , with a blue and pink wire going to it , clipped on the top left of the coils .
If you do get a red glow , then the # 4 thermistor is bad . This tells the main control board , the temp of the coils , if they need defrosted , when they are thru defrosting . This thermistor is the 1 " long , torpedo looking piece , clipped on the top left of the coils , with 2 white wires going to it . Part number WR55X10025 . It would be advisable to also replace the # 5 thermistor , located at the bottom of the freezer , slightly in front of the drain , also with 2 white wires going to it , slid into a housing . This thermistor , is the freezer thermistor , which tells the control board , the freezer temp and when to cycle off due to selected temperature .

GE refrigerator won't keep cool


check the voltage going into you fan w/ the old main board and also w/ the new board. You might be getting a low voltage w/ your new board or the fan you replaced is for a diferent voltage. Have you tried to put the old fan back w/ the new board??

Yes , your main control board is on the recall list , however , that is not the problem . The problem , is the #4 and/or # 5 thermistor . The #4 , tells the control board , the temp of the coils , when to defrost , and when to stop defrosting . The # 5 , tells the control board , the freezer temp . Both thermistors work together , relaying information to the board , to act on . The # 4 , is behind the inside rear freezer panel , clipped on the top , left side of the coils , with 2 white wires going to it . The # 5 , is located behind the bottom freezer crisper , slid inside a small housing , also with 2 white wires going to it . The part number for each thermistor is WR55X10025 . I would replace both thermistors .

Where is the thermostat on a GE profile refrigerator Side-by-Side


There is no thermostat ( cold control ) on your model refrigerator . It works off thermistors ( 3 in the refrig section and 2 in the freezer section ) . These thermistors , operate by the coldness which in turn , less resistance to the main control board the colder or warmer it will provide .

GE refridgerator fan speed changes constantly


I will try to answer your question . Your refrigerator had 3 thermistors in the refrig side , and 2 in the freezer side . These thermistors , send resistance messages to the main control board , mounted on the back of the refrigerator . If say #1 thermistor tell the board , I need to be colder , then the board will tell the damper ( small vent in the top of refrig section ) , to open . If the #2 thermistor tells the board , I need to be colder , then the board tells the fan to speed up , to get more air to the refrigerator section . #3 thermistor , works with the turbo cool switch , turning the fan to a high speed also . If the thermistors tell the board , we're all fine , then the fan will slow down , but still circulate to make/keep the freezer colder . If the freezer thermistors say , we're ok also , then the refrigerator will cycle off , until a thermistor asks to be cooler again . The fan works off D C voltage , in which fan speed is regulated (faster or slower) , by the thermistors "talking" to the control board .
