Fridge Not Cooling in Dhaka? 6 Real Causes & When You Need a Technician
📋 In This Guide
Before we get into the causes, one quick note: refrigerators in Dhaka work particularly hard. Ambient temperatures regularly hit 35–38°C in summer, power fluctuations are common, and load-shedding forces fridges to restart repeatedly — all of which puts extra stress on the compressor and electrical components. A fridge that works fine in Europe’s climate might struggle here, and problems that take years to develop elsewhere can appear within 3–5 years of purchase in Dhaka.
The 6 Most Common Reasons Your Fridge Isn’t Cooling
Dirty Condenser Coils
The condenser coils (usually located at the back or underneath your fridge) release the heat that’s pulled from inside the refrigerator. In Dhaka kitchens, where dust and cooking residue build up quickly, these coils can get coated within months. When coated, heat can’t escape efficiently, and the fridge has to work harder — eventually struggling to maintain temperature. Cleaning these coils every 6 months can solve this entirely.
Worn Door Gasket (Door Seal)
The rubber seal around your fridge door keeps cold air in and warm Dhaka air out. Over time — especially with frequent opening and closing in a busy household — these gaskets crack, harden, or lose their magnetic grip. When cold air leaks out continuously, the compressor runs nonstop trying to maintain temperature and eventually can’t keep up. This is one of the most commonly missed causes of a fridge not cooling properly.
Low Refrigerant Level
Just like an AC, your refrigerator uses refrigerant to create cold. A slow leak in the refrigerant circuit — most commonly at the evaporator coil or at pipe joints — will gradually reduce cooling performance. Early signs include the fridge feeling less cold than usual, ice building up in unusual places, or the freezer section working but the fridge section staying warm. Our fridge gas refill service in Dhaka addresses this properly.
Faulty Evaporator Fan Motor
Inside your fridge, a small fan circulates cold air from the freezer coil into the refrigerator compartment. If this fan motor fails, the freezer might still be cold while the fridge section warms up. You might notice the fridge is silent when it shouldn’t be, or that food in the fridge section is spoiling while items in the freezer remain frozen.
Defrost System Failure
Modern fridges have an automatic defrost system that prevents ice from building up on the evaporator coils. When this system fails (usually the defrost heater, defrost thermostat, or control board), ice builds up on the coils, blocking airflow and reducing cooling. Signs include frost buildup visible inside the freezer compartment, or ice coating the back wall of the fridge section.
Compressor Failure or Start Relay Issue
The compressor is the engine of your refrigerator. If it fails completely, the fridge will stop cooling entirely. Before the compressor itself fails, a small component called the start relay often goes first — and replacing a start relay (which costs BDT 200–500) can sometimes restore full function without an expensive compressor replacement. You may hear a clicking sound and then silence if the start relay is faulty.
Power surge damage is very common in Dhaka. If your fridge stopped cooling suddenly after a power cut or fluctuation, the main control board or starting components may be affected. Don’t assume the worst — a technician can diagnose whether it’s a small component or a major issue before you consider replacement.
What You Can Check Yourself Before Calling a Technician
🔍 5-Minute Self-Check List
- Is the fridge plugged in and switched on? Check the power socket with another device. Voltage fluctuations from load-shedding sometimes trip circuit breakers.
- Is the temperature dial set correctly? The ideal fridge temperature is 3–5°C. Many families set it too low in summer, causing the fridge to run less than needed.
- Check the door seal: Close the fridge on a piece of paper. If you can slide the paper out easily, the seal has lost its grip and needs replacement.
- Look at the back wall inside the fridge: Visible ice buildup on the back wall inside the refrigerator section often indicates a defrost system problem.
- Listen for the compressor: You should hear a low hum every 15–20 minutes. If the fridge is completely silent for hours, the compressor isn’t running.
When to Call a Technician: Problem-to-Action Guide
| What You’re Experiencing | Likely Cause | What to Do |
|---|---|---|
| Fridge not cold, freezer fine | Evaporator fan or defrost failure | Call a technician |
| Both fridge and freezer warm | Compressor, refrigerant, or relay | Call a technician urgently |
| Ice buildup on back wall | Defrost system failure | Defrost manually, then call |
| Paper slides out from door easily | Worn door gasket | Replace gasket (affordable) |
| Fridge runs constantly without cooling | Dirty coils, low gas, or compressor | Coil clean first, then diagnose |
| Clicking sound then silence | Faulty start relay | Call a technician (often cheap fix) |
| Stopped after power cut | Control board or power surge damage | Check breaker, then call |
