LG Fridge Light On but No Cooling in Kolkata? Call Now for Fast Doorstep Repair
If your LG refrigerator light is on but there is no cooling, this is a clear sign that the power supply is working but the cooling system is not functioning properly. Many customers across Kolkata face this issue and assume it is a minor problem. In reality, it can be linked to serious internal faults like compressor failure, relay damage, PCB board issues, or defrost system malfunction.
In areas like Salt Lake, New Town, Dumdum, Lake Town, Garia, Tollygunge, Behala, Jadavpur, Howrah, Baranagar, Park Circus, Ballygunge, Sealdah, and Madhyamgram, this is one of the most common refrigerator complaints, especially during summer and monsoon seasons.

If you are searching for LG fridge light on but not cooling in Kolkata, this detailed guide will help you understand the real technical causes and when you should call a technician.
Please note clearly: We are not an LG authorized service center. We provide independent LG refrigerator repair service across Kolkata.
Now let’s understand the main technical reasons behind this problem.
Compressor Not Starting
The compressor is the heart of your refrigerator. When the light is on but there is no cooling, the first thing a technician checks is whether the compressor is starting properly.
Normally, when you plug in the fridge, you should hear a soft humming sound from the back. If there is complete silence or a clicking sound every few minutes, it usually indicates that the compressor is not starting.
Common signs include:
The fridge light works normally
No cooling in freezer or fridge section
Clicking sound from backside
Compressor gets hot but does not run continuously
In many Kolkata households, voltage fluctuation is a major cause of compressor starting failure. Areas like Barasat, Madhyamgram, Behala, and parts of Howrah often experience unstable voltage, especially during peak electricity usage hours.
Low voltage or sudden power spikes can damage the starting mechanism of the compressor. In inverter LG models, the issue may also involve the inverter control system.
Sometimes the compressor itself is not fully damaged. It may just be struggling to start due to a faulty relay or overload protector, which brings us to the next cause.
Relay or Overload Protector Fault
The start relay helps the compressor begin its operation. The overload protector protects the compressor from overheating. If either of these components fails, the compressor will not run, even though the fridge light is on.
This is one of the most common reasons behind the “LG fridge light on but no cooling” complaint in Kolkata.
Symptoms of relay or overload protector failure:
Repeated clicking sound from the back
Compressor tries to start but shuts off immediately
No cooling at all
Backside feels slightly warm
In humid regions like North Kolkata, Shyambazar, Ultadanga, and Kidderpore, moisture sometimes affects electrical components over time. Dust accumulation behind the fridge also contributes to overheating and relay damage.
The good news is that relay and overload protector replacement is usually more affordable compared to compressor replacement. However, proper testing with a multimeter and clamp meter is necessary before confirming the issue.
Replacing parts without diagnosis can lead to unnecessary expenses.
PCB Board Issue
Modern LG refrigerators, especially double door and inverter models, operate through an electronic PCB control board. This board manages the compressor, fan motors, temperature sensors, and defrost cycle.
If the PCB board becomes faulty, the fridge may show power but fail to start the cooling system.
Common signs of PCB failure:
Display panel working but no cooling
Compressor not receiving signal
Random beeping sounds
Cooling stops suddenly after working for some time
In areas like Salt Lake Sector 1, 2, 3, New Town, Rajarhat, and EM Bypass, where many homes use advanced LG inverter models, PCB related issues are more common compared to older single door fridges.
Voltage spikes, lightning during monsoon, or internal short circuits can damage the PCB board.
PCB repair requires technical skill. In some cases, minor component repair is possible. In other cases, full board replacement is required. Proper inspection is essential before deciding.
If your LG refrigerator light is on and freezer has heavy ice buildup but the fridge section is not cooling, the problem may be related to the defrost system.
The defrost system includes:
Defrost heater
Defrost thermostat
Defrost timer or control board

If the defrost heater stops working, ice builds up around the evaporator coil. This blocks airflow, preventing cold air from circulating into the fridge section.
Common symptoms:
Thick ice layer inside freezer
Freezer slightly cold but fridge warm
Water leakage after manual defrost
Cooling improves temporarily after switching off for some hours
This issue is common in areas with high humidity such as Park Circus, Kasba, Tangra, and Gariahat.
When customers manually switch off the fridge for 8 to 10 hours, cooling temporarily returns because the ice melts. But the problem comes back again in a few days.
Proper repair involves checking the heater continuity, thermostat function, and control signal from the PCB.
Why This Problem Should Not Be Ignored in Kolkata
Kolkata’s climate increases refrigerator workload. High temperature and humidity mean the compressor runs longer to maintain cooling.
If your LG fridge light is on but no cooling is happening, ignoring the issue can result in:
Complete compressor burnout
Food spoilage
High electricity bills
Damage to PCB board
Permanent gas system damage
Early diagnosis saves money and prevents major breakdown.
When Should You Call for LG Fridge Repair in Kolkata
You should call immediately if:
There is zero cooling in both sections
Clicking sound continues repeatedly
Compressor becomes very hot
Ice buildup increases rapidly
Cooling does not return after resetting
Whether you are in Salt Lake, New Town, Dumdum, Lake Town, Garia, Tollygunge, Behala, Jadavpur, Howrah, Baranagar, Sealdah, Ballygunge, or nearby Kolkata areas, quick service is important.
