Why is my whirlpool fridge not cooling but freezer works. If you think all of your food will spoil and rot away right in front of your eyes, take heart knowing that it may actually have nothing to do with whether the refrigerator is working properly or otherwise.
It could well be something more simple that can be easily remedied.
Why is my whirlpool fridge not cooling but freezer works
When your refrigerator isn’t running right, one common issue is a burnt-out cooling fan motor.
This particular component is responsible for powering a fan that blows cold air in order to keep the temperature cool enough to preserve food meaning it’s an incredibly important part and must be replaced as soon as possible if found broken.
Unusually noisy motor
The evaporator fan motor draws in cold air from outside and cools it over the evaporator coils. The air is then circulated around the rest of the interior through inside vents.
The primary function of an evaporator fan is to help keep things cool, but that only works if that fan is switched on when you ask it to an easy check is to see if the blade turns freely by hand.
if it’s getting stuck or very hard to turn then that’s a good sign that it’s time for a replacement.
Similarly, electrical faults can be made obvious using a multimeter just to hold the two probes against each other at various points on the open windings (the outside insulates them). If no current is found, replace your evaporator fan motor with a new one.
Evaporator coils are frosted over
If your refrigerator/freezer stops cooling, the evaporator coils may be frozen over, causing restricted airflow through these essential components.
Testing each part of the defrost system can help diagnose the cause of your frozen coils and fix the problem if you find out any broken parts are to blame for their blockage.
To test each part of your defrost system and identify any problems, remove the cover from your refrigerator/Freezer and locate a red cap over the top-right corner (from the front) on the back wall.
This is where you should begin testing this portion of your defrost system to see what’s not working properly.
Defective Thermistor
If your fridge has stopped cooling, the thermistor could be at fault.
The thermistor is a part that measures temperature and controls several other parts of your fridge.
It’s basically controlled by a thermostat on the control board and should respond to changes in temperature accordingly. If the thermistor fails in any way.
This will prevent your fridge from running smoothly or at all.
One way to find out if your thermistor is faulty is to check it for continuity with a multimeter as described here.
The damper Control Assembly is broken
The air damper controls the flow of cold air from the freezer to the refrigerator portion of the appliance. The damper door may be inoperable if it is buckled or otherwise stuck closed or open.
Check the damper level and ensure that it is properly aligned and not warped or damaged.
Faulty Control Board
The defrost control board is responsible for activating the defrost fan.
If this board fails, the refrigerator will not run the defrost cycle and may have frost accumulating on its evaporator coils which in turn will make it work harder to remove heat as a result of buildup.
This in turn could cause your refrigerator to be warmer than usual therefore it’s highly recommended you replace the defective defrost control board with a new one.
Problem with the 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 one or both of these components.
Before replacing your control board, test all of the other components on your refrigerator. The compressor is consistently unreliable and should be replaced as an initial step before you begin testing any other parts in your appliance.
The defrost system is not working
The defrost timer will automatically turn on a defrost cycle in order to melt any frost that might have accumulated on the evaporator coils.
If the defrost timer is defective, it might not send power to the defrost heater or advance into the defrost cycle.
As a result, frost will continue to accumulate on the evaporator coils and this can lead to an increase in everyday energy use. To determine whether it’s the problem of your malfunctioning refrigerator.
Try advancing through each stage of operation by listening for a click/tap noise as you carefully rotate the dial forward because once you reach this setting tap your hand against the cover of your refrigerator several times.
It will take 30 minutes for things to start warming up again – so make sure you’re focusing intently once you hear the click/tap noise.
