Refrigerator not cooling.

Lights come on and evaporator fan in freezer section runs. Fan in condenser section runs. The lights blink when power goes to the compressor but they quickly blink again like the compressor is trying to turn on but can't. Is this an indication that the compressor starter may be defective or the compressor may itself may be defective?

    Thank you for responding. I didn't expect a response because I clicked away from the site without submitting my post.

    Our refrigerator is a Whirlpool, side by side, Model Number:
    GD5SHAXKB00.

    Neither section of the refrigerator is cooling at all. The lights in both sections come on and the fan in the rear of the freezer section above the evaporator coil is running. Also the fan next to the compressor located under the bottom of the refrigerator is running. When I turn the thermostat from the off position to the maximum cool position, the lights blink like the compressor is being called upon to start running, but it doesn't start and in just a few seconds the lights blink again like the voltage to the compressor has been cut off. In a few seconds this repeats. So I turned the thermostat back to the off position again until the problem is corrected.

    I'm prepared to order a start capacitor or starter assembly for the compressor just to see if this will correct the problem. If it doesn't, then I suppose the compressor is likely defective and will need to be replaced by a qualified technician.

    What do you think?


  • tomajud Jun 02, 2008

    The compressor doesn't have a separate motor. It is a sealed unit and the motor is inside the sealed unit and therefore doesn't require lubrication. If the compressor is defective, it is not repairable. It must be replaced.

    However, there is a separate starter capacitor that could be defective and the compressor can't start up if the starter capacitor is defective.

    I will order the capacitor and replaced it and if that doesn't correct the problem, I will have it repaired by a qualified service technician.

    Thank you very much for your help.

    What model / make unit is this unit? Chances are this is an error code and it will need service.

If the compressor is extremely hot, it could be seized, if this is the case you would have to have a new one installed.

Can you turn the compressor by hand? Did you clean the area around the motors with a vacuum and blown out the armature of the motor? What connects the motor to the compressor? Are there lub ports on the drive motor?

    Good Luck. You could put a meter on the capacitor and see if it gets voltage when you turn the thermostat down. I suspect you've done that.

Samsung RB31F Fridge/Freezer - fridge temperature too high, freezer OK


1-The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won't dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty-if the condenser coils are dirty, clean them.
2-The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.

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.

The freezer and fridge do not cool properly


Hi


Check the back wall or floor of the freezer section for frost. Check the freezer ( evaporator) fan to see if it is running. Check the condenser coils under the unit for blockage from dust. Check the condenser fan (under the unit) to see if it is running.
If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost terminator, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. These things usually require dismantling the freezer and other areas of the refrigerator to be checked.

There can be many factors for the no cooling factor: the condenser coils could be blocked with dust, the condenser fan could be bad or stuck, the freezer fan could be stuck or bed, the freezer coils could be blocked with frost because the self-defrost system is not working or the compressor is not running because of a bad relay etc.

Refrigerator not cool enough


Is it running? If so, the evaporator fan in the freezer and the condenser fan(if there is one) by the compressor need to be running. Check if compressor is running. Is there any frost build up on the evaporator cover? If so you have a defrost problem (bad heater, defrost thermost, thermister, defrost timer or circuit board). Check air channels between freezer and refrigerator sections for any ice blockage. If everything checks good you may have a sealed system problem which requires a repairman to fix and is expensive.

The refrigerator has quit working. Lights come on and fan appears to be running. Not cooling


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. 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).
If it's iced up really heavy you have an auto defrost problem. Melt the ice with a hairdryer and check the defrost system.

Subzero 590: freezer works, refrigerator not cooling


This is a Sub Zero and many technicians do not realize that these units most all run on 2 separate systems. 2 cold controls 2 compressors 2 evaporators. They share a condenser and condenser fan motor. What you are describing is most likely a bad cold control. It is pretty common for these to get some age and go bad. If you are very savvy with repairs yourself then if you access the compressor area and feel that the compressor on the right is cool and the compressor on the left is warm then you know that the ref. compressor has not been running. UNPLUG THE UNIT OR CUT THE BREAKER OFF. Remove the shelving from the fresh food section and the cover to the lights and the panel below the lights and lean the back panel forward to access the cold control. You will see 3 wires to the cold control. The green wire is the ground wire of corse. Unplug the other 2 wires remembering their location on the control unit. Take a jumper wire and jump these 2 wires. If when you power the unit up the right side compressor comes on then you know that your fresh food cold control is bad. Replace fresh food cold control.
