To check the fan motor, turn the fan blades by hand. They should spin smoothly. If there is any resistance, the fan motor could be bad.
To be sure, check the motor for continuity with a multimeter. If there is no continuity, replace the condenser fan motor.
The condenser fan ensures that the compressor and condenser coils do not overheat while working. If the motor is defective, the refrigerator will not cool due to the heat - appliance repair in toronto.
The condenser coils should not be dirty, at least not extremely dirty. Therefore, check if they are dirty, especially if you have never cleaned them or have pets. Take your vacuum cleaner head or a condenser brush and clean any dirt from the coils. And if there are any grease stains, clean them with a damp soapy cloth.
If the coils are dirty, they do not dissipate heat from the refrigerant, so it does not transport it to the refrigerator. Consequently, the cooling capacity of the refrigerator is reduced.
Like the condenser fan motor, try turning the evaporator fan blades by hand to check motor operation. If the blades are stiff, the motor is likely defective. Consider replacing it.
If the motor is noisy, it means something is broken or the motor is damaged. Replace it. And if the motor windings do not have continuity when you check them with a multimeter, replace the motor.
The fan is what circulates cold air in the freezer and refrigerator. If the motor is defective, the fan will not work. So while the freezer may be cold, there will not be enough cold air to cool the refrigeration section. Therefore, it will stop cooling.
If these parts are troubleshooted and none of them are defective, then check the temperature control thermostat, thermistor, start relay and start capacitor.
You can also check the main control and temperature control boards along with the compressor, but they are almost never the cause of the refrigerator not cooling. Additionally, you will need the services of a certified refrigerator technician to check its condition as they are too technical, especially the compressor.
