Refrigerator Freezer is Cold But Refrigerator is Warm

The part(s) or condition(s) listed below for the symptom Refrigerator Freezer is cold but refrigerator is Warm are ordered from most likely to least likely to occur

Refrigerator Freezer is cold but refrigerator is Warm

Cause 1 – Evaporator coils are frozen.

Defrost heater assembly turns on and off several times during the day to melt any frost that may have been accumulated in the evaporator coils. If the defrost heater assembly is faulty, frost will continue to accumulate in the evaporator coils tamponing the coils. If the evaporator coils are frosted, air flow thru the coils may be restricted, causing the refrigerator not to cool down. Verify the evaporator coil to determine if they are frozen. If they are, test every component of the defrosting system. This is the fist possibility if Refrigerator Freezer is cold but refrigerator is Warm

Cause 2 – Evaporator fan’s motor

The evaporator fan moves air over the evaporator coils and circulates it all over the freezer. if the evaporator fan is not working, the freezer or the refrigerator will not cool down properly. To determine if the evaporator fan is faulty; first check the blade of the fan for obstructions like frost, then try spinning the blade with your hand. If the blade does not spin freely, replace the fan. If the fan is unusually loud during operation, replace it. Finally if the fan is not working, use a multimeter to test the continuity in the motor of the fan; if the windings have no continuity, replace the evaporator fan’s motor. This is the second possibility if Refrigerator Freezer is cold but refrigerator is Warm

Cause 3 – Damper Control Assembly.

Damper control opens and closes allowing cold air to flow into the refrigerator compartment. If the regulator is not working properly, it will not open and not enough air will flow to the refrigerator. Check the damper control assembly to make sure it is not broken or jammed.

Cause 4 – Thermistor

The sensor that controls air temperature inside the refrigerator and sends the reading to the control board is named thermistor. The control board regulates both the compressor and the evaporator fan in accordance to the thermistor readings. If the thermistor is faulty, then the compressor and the evaporator fan may not function when needed. As a result the refrigerator will not maintain proper temperature.  To determine if the thermistor is faulty, test it with a multimeter, the resistance on the thermistor must change as temperature inside the refrigerator changes. If the resistance at the thermistor does not change or the thermistor has no continuity, replace it.

Cause 5 – Temperature control board

The temperature control board provides electricity to the compressor and the fan motors. If the board is faulty, it will not send energy to the cooling system when required; this however almost never happens. Very often, temperature control boards are misdiagnosed as faulty; before replacing it, test all other most commonly faulty elements. If no other component is faulty, consider replacing the temperature control board

Causa 6 – Defrost control board

The defrost control board determines how often the defrost cycle is run. If the board is faulty, the refrigerator will not enter the defrost cycle and ice will continue to accumulate in the evaporator coils. If evaporator coils are too frosted, the refrigerator will have to work harder to maintain proper temperature; as a result the refrigerator may too hot.  Before replacing the defrost control board, make sure the heater and the defrosting thermostat are functioning correctly. If they are, it’s very likely that the defrost control board is faulty and needs replacement.

Cause 7 – Defrost timer

The defrost timer turns on the heater several times during the day to melt away any frost accumulating in the evaporator coils. If the timer is faulty, it is possible that the defrost cycle won’t start or that no energy is sent to the heater. . If the timer is faulty, the refrigerator will not enter the defrost cycle and ice will continue to accumulate in the evaporator coils. If evaporator coils are too frosted, the refrigerator will have to work harder to maintain proper temperature; as a result the refrigerator may too hot.  To determine if the defrost timer is faulty, slowly advance the dial to the defrosting cycle; compressor must turn off and heater must turn on. If no energy is sent to the defrost components, or it advances out of the defrost cycle, it’s a good indicator that the defrost timer is faulty and need replacement.

Cause 8 – Defrost thermostat

The defrost thermostat, controls the temperature on the evaporator coils. When temperature on the evaporator coils falls below the set temperature, thermostat contacts are closed allowing energy to enter the defrost heater during the defrost cycle. During the defrost cycle, the heater melts any frost accumulating in the defrost coils. If the defrost timer is faulty, contacts on the thermostat will not close and energy will not get to the heater. To determine if the defrost thermostat is faulty, use a multimeter. If the thermostat has no continuity when it reaches below operation temperature, replace it.

Cause 9 – Main control Board

The main control board regulates energy input for all components on the refrigerator; includen elements of the defrost system. If the main control board is faulty; it may stop sending energy to the defrost system components. This however is rare, main control boards are often misdiagnosed as faulty; before replacing the main control board, test all components of the defrost system, if none of them is faulty; consider replacing the main control board. This is the lower possibility if Refrigerator Freezer is cold but refrigerator is Warm

5 thoughts on “Refrigerator Freezer is Cold But Refrigerator is Warm

  1. Some information about why your refrigerator freezer might be cold while your refrigerator is warm

    We are so sorry to read that your refrigerator freezer is cold but refrigerator is warm; although, we have great news for you. There is no need to be worried; we have possible explanations and solutions to deal with this.
    It is possible that the problem with your refrigerator is caused by the evaporator coils. Sometimes, the coils are blocked because of the accumulation of frost. If this is what´s happening the air is not flowing thru the coils, which could be causing that the refrigerator does not cool down. This could be the first option you might consider if your refrigerator freezer is cold but refrigerator is warm.
    Another possible explanation is that the evaporator fan is not moving air thru the evaporator coils, which is dulling the circulation of the air all over the freezer. If there is a problem with the evaporator fan, it won’t cool down, and might be causing that your refrigerator freezer is cold but refrigerator is warm.
    To find out if the evaporator fan is imperfect you must check the blade of the fan, because it could be blocked by the frost. If you try to spin the blade of the fan and it doesn’t spin properly or the fan is doing strange and loud sounds you might need to replace it. In case you confirm that the problem is with the motor of the fan, you might also need to replace the evaporator fan’s motor.
    There are some other options that may explain what is going on with your refrigerator. For example, if the damper control, which is a regulator that allows the cold air to flow into the refrigerator compartments, is not working as it should be, the flow of the air will be diminished, and the refrigerator freezer will be cold but the refrigerator will be warm.
    The problem that might be causing that your refrigerator does not cool down, is that the sensor that controls air temperature, which is call thermistor, is not sending the readings to the control board. In this case, the refrigerator won’t preserve the right temperature. So, you might need a multimeter to determine of your thermistor is working as it´s supposed to do. If the sensor has no continuity you must replace it.
    Other sources of the problem could be: the board is not sending the required energy to the cooling system, defrost control board is not working properly, so it is not doing the defrost cycle, problems with the timer, etc. All of this requires you to diagnosed the system and determine what the real cause is.
    And at last but not least, your fridge could have problems with the main control board. This element, among some other things, regulates energy for the defrost system. If this energy is not send to the components, the system will just stop working. This is a rare possibility, that´s why I recommend you to keep testing the rest of the elements and just replace the main control board when you are completely sure it is not working at all.
    It is important for you to know that the determination of the cause that is provoking that your refrigerator freezer is cold but your refrigerator is warm, is essential in order to find an accurate solution for your problem.

  2. To repair an appliance with the required quality we have to detect the real problem to avoid more complications. When we hear “Refrigerator Freezer is Cold But Refrigerator is Warm” we can think about a lot of possibilities, but the true is that we can order, from the most likely to least likely, nine causes for the symptom “Refrigerator Freezer is Cold But Refrigerator is Warm”. In fact, many causes are related with the defrosting system, so, that give us at least a clue.
    Firstly, we must check the state of the Evaporator Coils. In a simple manner to understand: the evaporator coils can´t be frosted. If everything is okay, then we can check the next cause: a bad performance of the Evaporator fan´s motor. If the blade of the fan has any obstructions like frost, for example, we remove it and then, try to spin the blade with our own hand, and the expected result would be that the blade spins freely. Maybe there is not any obstruction, but the fan is not working or, is working but is unusually loud; in any case we most replace the fan or the evaporator fan´s motor depending on the situation. Often, the third cause use to be the Damper Control Assembly. If damper is working properly, the cold air will flow to the refrigerator compartment.
    Another cause is the Thermistor or temperature sensor, and it function is the control of the air temperature. Thermistor represents an important component, if it is faulty, data can be received by the control board, and the whether doesn´t maintain inside the refrigerator.
    If the problem persist and “Refrigerator Freezer is Cold but Refrigerator is Warm”, we most check then the Temperature Control Board, that handles the electricity needed by the compressor and the fan motors. In the others cases a quick solution seems to be to replace the component without any doubt, but in this case, before any replacement, we most discard a misdiagnosis. For that reason it is necessary to test all other elements of the system.
    The Defrost Control Board can be damaged, then the defrost cycle is not running well; or The Defrost Timer doesn´t turns on the heater several times during the day and frost becomes in problem; or can be The Defrost Thermostat, or The Main Control Board. In any case, the most important, in order to save time and resources and preserve the functional life of the refrigerator, is the review or examination; where we can determinate the real problem and then, to try to find a way to fix it with the quality that allow a good performance.

  3. The process to refrigerator repair is very complex because there are many reasons which the refrigerator freezer is could but refrigerator is warm. Some days ago my freezer had problems. I didn’t know why my freezer defrosted all food. My husband is a refrigeration technician and checked it. He told me that defrost system had problem, maybe was the timer. The timer didn´t stop the machine. Quickly, we bought a new timer and replaced it. One week later the refrigerator began with same symptoms, I exclaimed ¨¨OH my god is it very difficult the process to refrigerator repair, is necessary looking for other opinion¨¨My husband, very angered with me, checked it again and discovered the resistant was roasted, then he replaced it. Our refrigerator is very old Daewoo Model. Some weeks later, the equipment presented the same problems, but in this case hard froze first and then defrosted. The baby´s food was decomposed. In this occasion, my husband David decided checking overall refrigerator waiting and looking for something more. He worked all the day and hard. At least, he found others problems more. First of all he noted the temperature control board damaged because didn´t carry electricity to the compressor. He could repair it. Second step he had to test the thermistor with a multimeter and he changed it, because the thermistor didn´t maintain de proper temperature. Then, he observed the refrigerator for some weeks more and problem persisted. We didn´t know to do, but my husband had a brilliant idea again. He thought that many time the refrigerator was defrosting and maybe the system was affected by humidity. Then he cleaned piping and changed refrigerant gas. The refrigerator was working good three years more. After, the refrigerator broke again but in this time one friend of my husband visited our house. Both, David and Ale checked it and discovered a capillary was broken. I fast remembered my baby playing near the back structure of refrigerator. Then I asked to my child what happened and he answered me that a toy locked in. They repaired, painted and changed it the refrigerant gas again. We needed to buy news accessory and other part to replaced it because the originally was very old. Thus it was working two years more but then it broke up definitely. We were saving the food with our neighborhood because we didn’t have money to buy other new refrigerator. On April my mother gave me five hundred dollars to buy new equipment. We went out the shopping and found a big Samsung refrigerator. I loved it. It was big, confortable and beautiful. My husband said me it was very expensive but I didn’t hear. Then we bought the Samsung refrigerator and one month later it broke up too. Oh my God its very terrible for me to start the process to refrigerator repair. I should hear my husband. It was a terrible experience.

  4. A refrigerator is one -if not the most- needed appliance in a house, especially in a tropical country. Sometimes our refrigerator freezer is cold but refrigerator is warm and that is a major problem for us. But let’s not fret about it and we better start looking for a solution to our problem.
    There are many causes if your refrigerator freezer is cold but refrigerator is warm. First we should check if the evaporator coils are frozen, the air flowing thru the coils may be restricted, causing the refrigerator not to cool down. You could check as well the evaporator’s fan motor, if it’s not working properly the refrigerator will not cool down. In this case we will have to see if the fan is broken. To achieve that, first check the blade to see if it’s obstructed with ice then try to spin it and if it doesn’t or is loud during operation then you must replace the fan. If the fan is not working at all you have to replace the motor.
    You have done all that but still the refrigerator freezer is cold and the refrigerator is warm. Check the damper control making sure is not broken. After that you start thinking about the thermistor wich is the sensor that controls air temperature, you need to determine whether is broken or not and replace it in case is broken.
    If none of that have worked there are still many causes why the refrigerator freezer is cold but refrigerator is warm such as the temperature control board. The temperature control board sends energy to the compressor and the fan motor; if it’s faulty the cooling system will lack energy to work. Now this is a rare thing, so be certain before you replace it.
    At this point we still have a few more possible causes to rule out before we throw our precious refrigerator out. The defrost control board, defrost timer and defrost thermostat. The first determines how often the defrost cycle is run. The second turns on the heater several times during the day to melt away any frost accumulating in the evaporator coils. If the timer is faulty, the defrost cycle won’t start or no energy is sent to the heater and the refrigerator will not enter the defrost cycle and ice will continue to accumulate in the evaporator coils. And the third controls the temperature on the evaporator coils.
    And the last thing to check in order to fix the problem is the main control board that regulates energy for all the components including the defrost system and this choice is also rare and should be thought carefully.
    If you are not a handy person you should call a repairman instead of trying yourself. Well, these are all the choices we have if the refrigerator freezer is cold but refrigerator is warm.
