What are the Five common problems in domestic refrigerator?

1. Temprature drop problem- Temperature drop in a refrigerator can be caused by various issues. Check the thermostat settings, ensure proper ventilation around the appliance, and inspect the door seals for any gaps. If the problem persists, it might be a malfunctioning thermostat or a refrigerant issue, in which case, professional repair may be needed.
2. Controler PCB supply problem- If you suspect a controller PCB supply problem in your fridge, check the power supply to the PCB. Ensure there’s a stable power source, and inspect for any damaged wiring or loose connections. If the issue persists, it might indicate a faulty PCB or a component failure. Consider consulting a professional technician for a detailed diagnosis and repair.
3. Cooling fan motor not working – If the cooling fan motor in your freezer is not working, it could lead to temperature issues. Check for any visible obstructions around the fan blades. If there are none, the problem might be a faulty motor, a damaged fan blade, or a wiring issue. It’s advisable to consult a professional technician to diagnose and fix the problem, as dealing with electrical components requires expertise.
4. Ducting vents blocked- Blocked ducting vents in a deep refrigerator can impede proper airflow, affecting cooling efficiency. Inspect and clear any debris or ice obstructing the vents. Ensure the vents inside the fridge and freezer compartments are not blocked by food items. If the issue persists, it might indicate a more complex problem, and seeking assistance from a professional technician is recommended for a thorough inspection and repair.
5. Condenser coil dusting blockage- A dusty condenser coil can reduce a refrigerator’s efficiency. Unplug the fridge, locate the condenser coil (usually at the back), and gently vacuum or brush away accumulated dust and debris. Ensure proper ventilation around the appliance. Regular maintenance helps prevent blockages and ensures optimal cooling performance.
