Samsung refrigerator not cooling freezer ok. When you find that your fridge or freezer units work fine, but not both at the same time, it may be puzzling. After all, both of these components are responsible for keeping your refrigerated items chilled and frozen items frozen.

But if you think about which components can cause either one to work properly even when the other is stuck in a broken-down state, it’ll be easier to figure out what might have gone wrong.

For example, from a frozen evaporator coil to used refrigerator coils we will follow along as we troubleshoot through the common refrigerator problems that tend to cause simultaneous working units but different functioning temperatures.

You might have a problem with your evaporator coils, so check to make sure they’re not frosted over.

If the fan is broken, you may need a replacement. Check to see if the fan blade turns easily. If it doesn’t move freely, try replacing it.

Defective Temperature Control Board

The temperature control board provides voltage to the compressor and fan motors. If the control board is faulty, it may stop sending voltage to either the compressor or fan motors.

It is generally easier to replace a faulty temperature control board than to test the more commonly defective components first since they are very difficult to access.

But as the last option if none of the other components are defective, consider replacing the temperature control board.

Frost covers the evaporator coils

The defrost heater assembly checks the defrosted evaporator coils for insulating frost every so often, melting it away to make sure any accumulated frost does not obstruct airflow through the coils.

If the defrost heater assembly is faulty, for example, if its thermostat has failed or if it has been tripped too many times by a power surge then there could be the increased buildup of frost on the evaporator coils leading to restricted airflow through them and eventually all frozen up.

The result would be that your fridge might no longer be able to cool properly and freeze fresh food effectively. In case this should happen, Test each component of the defrosting system if the evaporator coils are frosted over.

Faulty Thermistorfaulty thermistor

The thermistor measures the temperature of the refrigerator and sends a reading to the control board.

The control board then regulates power to the compressor based on the thermistors measurements.

If the thermistor is defective, the refrigerator will not work properly or parts may become damaged. We need you to test it with a multimeter to see if it’s working correctly.

Make sure the two prongs on your multimeter match up with one of their corresponding threads. When testing with a multimeter, be careful that you don’t touch any other terminals besides those indicated on the previous diagram.

Also, make sure you are testing between an empty terminal and one filled with copper because these zones are what determine the resistance.

Problem with the Damper Control Assembly

Check the air damper control to see if it is stuck closed. If this happens, not enough cold air will get into the refrigerator.

The control opens and closes a smaller flap on the refrigerator that allows cold air in when you are adjusting temperatures and defrosting.

An unusually noisy motor

The evaporator fan motor stays cool by pulling in cool air from the freezer and passing it over the cold coils to keep everything inside at a satisfactory temperature.

If this fan motor is defective, the system will not cool properly, leading to spoiled food or a potentially hazardous condition if you’re using the fridge for storage.

To test for a faulty evaporator fan motor, use your hands to rotate the blade. If it does not budge freely, replace it.

If the warped metal is unusually loud when you turn it with your hand or if the motor doesn’t run at all, check its continuity through a multimeter and replace it immediately if there’s no power running through it.

The defrost timer does not advancethe defrost timer does not advance

A refrigerator defrosts timer is an electrical device that precisely controls the defrosting of a refrigerator unit.

The Defrost timers are found in an automatic icebox and freezing compartments, as well as in many different types of freezers.

With the appliance off, look on the inside walls of your refrigerator or freezer to find a dial labeled ‘defrost’. Sometimes need you may need to consult your owner’s manual for its exact location.

You should turn off the compressor and turn on the heater. This indicates that the defrost timer is not advancing if it does not send power to the defrost components or advance out of the defrost cycle within 30 minutes. Replace the defrost timer if it does not advance.

The defrost thermostat is not working

The defrost thermostat is a component in the control board that regulates how long the heater stays on.

As such, it prevents power from flowing to the evaporator coils when it detects frost building up, which ensures the reliability of your refrigerator/Freezer for years to come.

Should a defect occur, it will not supply any power to the defrost system and other parts may be damaged as a result. Taking basic precautions like cleaning the coils regularly and doing visual inspections are crucial for preventing defects from occurring on this device.

You should use a multimeter to check whether or not your unit works properly by ensuring there is continuity when the coils reach their lowest temperature.

If there isn’t any, you will have(need) to replace the Defrost Thermostat since its replacement could save you hundreds of dollars if you had to repair your entire control board.

Fault with the main control board

The main controller board is rarely the cause of a lethal error. Test all of the components first before replacing the controller board, because most component failures will not be fatal if removed and replaced.

If none of these components bear the blame for causing your malfunction, consider replacing the controller board.
