There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.
If your refrigerator is like mine, only the freezer is actually cooled. Cold air is blown from the freezer into the refrigerator section to cool it. If the fins in the cooling element get blocked by frost, the cold air can't get from the freezer into the refrigerator.
UNBLOCK THE AIR VENT. The air vents inside your refrigerator help circulate cold air throughout the interior to maintain proper cooling temperatures. If you overpack your appliance, you may have blocked the air vent. This can restrict the airflow and lead to freezing temperatures inside the refrigerator storage area.
Cause: The freezer may not be receiving power due to a blown fuse, tripped circuit breaker, or unplugged cord. Fix: Check the power supply, reset the breaker, replace fuses, or ensure the freezer is plugged in. Cause: Airflow can be obstructed by items stored too close to the vents.
Clear blocked air vents: Inspect the air vents inside the fridge and freezer compartments to ensure they are not obstructed by food or containers. Proper air circulation is vital for even cooling. Check the door seals: Inspect the rubber gaskets (door seals) around the refrigerator and freezer doors for damage.
If it's set too cold, set it higher and give it a day to adjust. Be sure to only adjust the temperature in relatively low increments, checking with a thermometer every 24 hours.
Be sure to check the electrical outlet, thermostat and airflow around vents. Cooling problems can also be caused by dust on condenser coils, faulty gaskets, clearance space around the refrigerator, a broken or stuck condenser fan or a faulty circuit board.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
To fix it: We recommend keeping your refrigerator about 3/4 full for the best results. Check to see if there's anything blocking the air vents. If not, then the problem might be with the vents themselves – they might be clogged or frozen over. In this case, you'll need to clean or defrost the vents.
A hum or a slight buzz is typical, but if your refrigerator starts making strange or loud noises, the compressor might be struggling. Professional Repair Required: Compressors have numerous components, and diagnosing the source of the noise can be complicated.
If your freezer is cold but the refrigerator section isn't staying cool, there are several possible causes that you can troubleshoot yourself. The most common issues are overstuffing the freezer, blocked condenser coils, a problem with the evaporator fan motor, and a faulty thermistor.
Keep an eye out for these dirty condenser coil symptoms for your refrigerator: Reduced cooling efficiency: Dirty refrigerator coils struggle to dissipate heat, which can mean your refrigerator doesn't cool as effectively. This is one of the most common refrigerator dirty condenser coil symptoms.
When the coils in a refrigerator freeze over, it usually indicates a defrost problem. The standard procedure to address this is indeed to turn off the refrigerator, remove all the contents, and allow it to defrost. This process can take several hours, depending on the amount of ice buildup.
Most refrigerators are designed to last between 10 and 20 years. If you're having any other problems on this list and the fridge is over ten years old, you'll probably save more money in the long run by simply replacing it. Otherwise, you could sink money into repairs for a fridge already on its way out.
First, unplug or shut off the power to your fridge on your home's circuit breaker. Leave it off for five to 10 minutes, then restore power and adjust the temperature settings to where you want them (aim for 32ºF-40ºF). It can take up to 24 hours for the refrigerator's temperature to stabilize.
If your evaporator fan is not working correctly, first unplug your refrigerator and remove and clean the evaporator fan blades. Ice buildup on evaporator fan blades often prevents your freezer from properly circulating air. If you notice a bent fan blade, you will need to replace it.
Resetting your refrigerator compressor really only consists of unplugging or disconnecting power from your unit, waiting, and reconnecting, with a few other steps. You should also ensure that your fridge hasn't accidentally been put into a display mode, meant for showroom units.
