Is your Indesit fridge not cooling even though it is running, you don’t have to worry. This article will walk you through the process of troubleshooting and fixing it.
Why is my Indesit Fridge Not Cooling?
If your Indesit fridge is not cooling, the following are the causes:
1. Dirty Condenser Coils
The function of the condenser coils is to give off heat as the refrigerant travels through them. Once the coils are clogged and noticeably dirty, the refrigerant not only experiences difficulty traveling through the coils, the coils will also be less efficient in dissipating heat.
In this case, the fridge works extra time trying to cool. To solve this problem, simply clean the coils with a vacuum brush, a clean rag, and water.
2. Defective Condenser Fan Motor
The condenser fan is responsible for cooling the compressor and the condenser coils. The process of drawing air across the condenser coils cools the coolant from a hot gas into a cool liquid.
The condenser fan is designed to work each time the compressor is working. If the fan does not work, the fridge will not cool.
To troubleshoot a defective fan motor, first, put off the power source. Next, check that the fan blades are spinning without obstructions. If there is none, run the fan blades with your hands to check that the blades spin freely. If you notice that it does not rotate without resistance, you have to change the motor.
However, if the fan passes both conditions, perform a continuity test on the motor using a multimeter. This will determine whether or not you are to replace it.
3. Defective Evaporator Fan Motor
Just like the condenser fan, the evaporator fan acts as a cooling device for the evaporator coils. It continuously blows air over the evaporator coils so that the coolant can absorb heat and be circulated around the fridge.
If the motor of the evaporator fan has a fault, the coolant will not flow throughout the fridge. To check if the motor has a fault, first, unplug the fridge. Then, turn the fan blades with your hands to check that it spins freely.
If you notice some restrictions, you may have to replace the motor. Also, if the fan motor is giving off a strange noise, you may need to get a replacement. Finally, run a continuity test on the motor windings. If there is no continuity, then a replacement is the best option.
4. Faulty Start Relay
The Compressor start relay functions hand-in-hand with the compressor. Once the start relay is burned out or has a defect, the compressor will experience difficulty running.
Consequently, the fridge will not cool. To troubleshoot a start relay fault, carry out a continuity test between the start and run terminal sockets. If there is no continuity, replace the start relay.
5. Bad Temperature Control Thermostat
This device functions by controlling the amount of coolant that gets into the fridge. It exerts control by switching the fridge on and off to maintain the needed temperature. To check for faults in the thermostat, change the thermostat setting and listen to hear a click.
If you hear the click, run a continuity test on the thermometer. Purchase a replacement if the thermometer has no continuity.
6. Broken Temperature Control Board
This component works by transferring voltage to the evaporator and condenser fan motors, as well as the compressor. Issues arising from temperature control boards are rare and often misidentified.
Before getting a replacement for the board, first, check to make sure that other components are not faulty. If all other parts are in good working condition, then replace the control board.
7. Faulty Start Capacitor
The start capacitor is a fairly simple, small component that is part of the compressor start relay. It works by giving an extra power boost to the compressor when it starts running.
When the capacitor is defective or burned out, the compressor will not start. You can easily know if the capacitor is faulty by using a multimeter. Replace the capacitor if it does not pass the test.
8. Defective Thermistor
The purpose of the thermistor is to sense the temperature change in the fridge and send signals to the control board when the temperature changes.
The control board then works to regulate power in the evaporator fan and compressor with regard to the signals sent by the thermistor. Once the thermistor has a fault, the evaporator fan and compressor may not work when necessary.
To solve this problem, check for continuity. You can easily get a thermistor replacement if the former has no continuity.
9. Broken Compressor
The compressor is a small cylindrical pump that compresses and pushes the coolant through the condenser coils and evaporator coils. For fridges with defective compressors, the cooling unit will have a difficult time working properly.
To troubleshoot a compressor, first, run a continuity test by placing the multimeter pins on either side of the compressor where the electrical pins are situated.
If you notice an open circuit, there is a need for replacement. You can either call an experienced technician or do it yourself to save costs.
10. Broken Main Control Board
Issues associated with the main control board are rare. Before tampering with the control board, make sure you carry out all the necessary tests to confirm that all other components are working. You can go ahead to replace the main control board if all the other components work. Check out the video below to see how to fix the main control board of your fridge…
