Why Your Refrigerator Is Not Cooling — Complete Troubleshooting Guide for Dhaka Homes

You open your fridge expecting a cold blast of air, and instead you get — nothing. The light is on, the motor seems to be running, but everything inside feels room temperature. If you are reading this at midnight in Uttara or Dhanmondi, you already know the panic that sets in. Perishables worth thousands of taka are sitting inside, slowly going bad.

Over the last 9 years running Ripon Refrigeration Works Ltd., I have handled thousands of calls from Dhaka residents facing this exact situation. Cooling failure is the single most common refrigerator problem we see, and the reasons behind it are more varied than most people think.

This guide breaks down every possible cause, what you can check yourself, and when it makes sense to call for fridge repair in Dhaka before your food spoils completely.

Common Reasons Your Fridge Stopped Cooling

1. Thermostat Is Set Wrong or Has Failed

This sounds too simple, but it happens more than you would guess. Someone in the house bumped the dial, or a child adjusted the digital settings. In frost-free models, the thermostat controls the compressor cycle — if it is stuck on the “off” position or set too high, the compressor never kicks in.

Test: Turn the thermostat to the coldest setting and listen for a click within a few minutes. No click usually means the thermostat itself has failed and needs replacement.

2. Condenser Coils Are Clogged With Dust

Condenser coils sit at the back or underneath your fridge. Their job is to release heat from the refrigeration cycle. When these coils get covered in dust, pet hair, or kitchen grease, they cannot dissipate heat properly. The compressor works overtime and eventually the cooling drops significantly.

This is especially common in Dhaka’s dusty environment. Homes near main roads in areas like Mirpur or Mohammadpur accumulate coil dust much faster.

3. Evaporator Fan Has Stopped Working

In frost-free refrigerators, the evaporator fan circulates cold air from the freezer compartment to the fridge section. If this fan fails, the freezer might still feel cold but the refrigerator section stays warm. You will usually hear a faint humming from the back that suddenly stops.

4. Refrigerant Gas Leakage

This is the most serious cooling failure cause. Refrigerant gas (R134a or R600a depending on your fridge model) runs through sealed copper coils. Over years of vibration, the copper develops micro-cracks, especially at joints and bends. Once gas starts leaking, cooling capacity drops gradually until the fridge stops cooling entirely.

Gas leakage is not something you can fix with a top-up. The leak point must be found, welded, and then fresh gas charged to the correct pressure. We cover this in detail in our fridge gas refill service in Dhaka page.

5. Compressor Problems

The compressor is the heart of your refrigerator. When it fails, nothing cools. Compressor issues generally fall into three categories:

• Electrical failure — the relay or start capacitor has burned out, so the compressor cannot start
• Mechanical failure — internal parts are worn, and the compressor locks up
• Gas starvation — low refrigerant causes the compressor to overheat and shut off on thermal protection

If you hear a clicking sound every few minutes from the back of the fridge, that is typically the relay trying to start a stalled compressor. At this point you need professional fridge compressor repair in Dhaka — there is no workaround.

6. Damaged Door Gasket

The rubber seal around your fridge door is called a gasket. When it gets cracked, warped, or loses its magnetic grip, cold air leaks out constantly. Your fridge compressor runs non-stop trying to compensate, but it cannot keep up — especially during Dhaka summers when room temperature sits at 33-36°C.

Test: Close the fridge door on a thin piece of paper. If you can pull the paper out without resistance, the gasket needs replacement.

Dhaka-Specific Factors That Worsen Cooling Problems

Dhaka presents some unique challenges that directly impact refrigerator performance:

• Voltage fluctuation — Areas like Uttara, Purbachal, and some parts of Mirpur experience frequent voltage drops. Low voltage causes the compressor to draw higher current, overheating the relay and start capacitor over time.
• Load shedding aftermath — When power returns after an outage, the voltage spike can damage compressor electronics. Repeated on-off cycling from frequent load shedding significantly reduces compressor lifespan.
• High humidity — Dhaka’s humidity averages 70-80% year-round. This means more frost buildup on evaporator coils in frost-free models, forcing the defrost system to work harder. If the defrost timer or heater fails, ice blocks airflow and cooling drops.
• Poor ventilation placement — Many Dhaka kitchens are small and enclosed. If the fridge is pushed against a wall with no gap for heat dissipation, the condenser cannot release heat efficiently.

Quick Checks You Can Do Yourself Before Calling a Technician

Before spending money on a service call, spend 10 minutes running through these checks:

1. Verify the thermostat is set correctly (not turned off or too warm)
2. Check that the fridge is actually getting power — try plugging in another device to the same socket
3. Listen for compressor sound — a low hum means it is running, silence or repeated clicking means it is not
4. Clean the condenser coils at the back with a soft brush or vacuum
5. Test the door gasket with the paper trick mentioned above
6. Check if the freezer section is still cold (tells you if the problem is airflow or the cooling system itself)
7. Make sure nothing is blocking the air vents inside the fridge compartment
8. Ensure there is at least 3-4 inches of clearance behind the fridge

If none of these resolve the issue, the problem is almost certainly in the sealed system (gas leak, compressor failure) or the electronic control board — both require professional diagnosis.

When to Stop DIY and Call a Professional

I have seen homeowners cause thousands of taka in additional damage by trying to fix things themselves. Call a technician immediately if you notice:

• Oil stains near the compressor or under the fridge (indicates a refrigerant leak)
• Burning smell coming from the back of the fridge
• The compressor is hot to the touch but not running
• Frost building up heavily on the back wall of the fridge section (not the freezer)
• Water pooling under the fridge that keeps coming back
• Sparking or unusual electrical sounds

Delaying professional repair when these signs appear usually turns a simple fix into an expensive one. A relay replacement that costs 800-1200 taka today can become a full compressor replacement costing 8,000-15,000 taka if you wait too long.

Fridge Cooling Repair Cost Breakdown in Dhaka (2025)

These are approximate ranges based on our service data. Actual costs depend on your fridge brand, model, and part availability. We always provide a price estimate before starting any repair — no surprises.

Which Fridge Brands Face Cooling Issues Most in Bangladesh

Based on the repair data from our workshop, here is a honest breakdown of what we see most often:

• Walton — Very high sales volume means we see many Walton fridges. Common issues include gas leakage from evaporator coil joints and thermostat failures in older models. Parts are easily available and affordable.
• Singer — Similar pattern to Walton. Direct cool models tend to develop gas leaks after 5-7 years. Frost-free models occasionally have defrost timer issues.
• Samsung — Build quality is good, but when things go wrong, parts are expensive and sometimes hard to find in Dhaka. Compressor relay failures are common in models from 2016-2020.
• LG — Generally reliable. The main issue we see is compressor failure in heavily used units (restaurants, small shops). Smart inverter compressors are harder to repair and usually need full replacement.
• Whirlpool — Frost-free models sometimes develop evaporator fan issues. Gas leakage is less common compared to local brands.

Prevention Tips to Avoid Future Cooling Problems

• Get your fridge serviced at least once a year — our appliance repair services include thorough cleaning and inspection
• Never overload the fridge — blocking air vents is the fastest way to kill cooling efficiency
• Keep 4-6 inches gap behind the fridge for proper heat dissipation
• Use a voltage stabilizer if your area has frequent fluctuations — this alone can add years to your compressor’s life
• Do not put hot food directly into the fridge; let it cool to room temperature first
• Clean the door gasket weekly with a damp cloth to prevent mold and maintain the seal
• If you live in an area with frequent load shedding, consider a small UPS for the fridge to prevent on-off cycling

Frequently Asked Questions

Do you provide same-day fridge repair in Dhaka?+

Will my fridge cool properly after gas refill?+

Yes, but only if the leak has been properly repaired first. Simply adding gas without fixing the leak will give you temporary cooling for a few weeks before the problem returns. We always locate and weld the leak point before charging fresh gas.
