Fridge Compressor Repair or Replacement — Honest Cost Guide for Dhaka Homeowners
What’s Inside
When a technician tells you your fridge compressor has a problem, the first thought that hits most people is: “How much is this going to cost me?” The second thought is usually: “Should I repair it or just buy a new fridge?”
I understand the anxiety. The compressor is the most expensive single component in your refrigerator, and making the wrong decision can cost you thousands of taka unnecessarily. At Ripon Refrigeration Works Ltd., we have replaced and repaired hundreds of compressors across Dhaka since 2015. This guide will give you the honest numbers and a clear framework to make the right call.
How a Fridge Compressor Actually Works
Think of the compressor as a pump. It takes low-pressure refrigerant gas from the evaporator (inside the fridge), compresses it into high-pressure hot gas, and sends it to the condenser (outside the fridge) where the heat is released. This cycle runs continuously while the fridge is plugged in — typically the compressor runs for about 30-40% of the time in normal conditions.
The compressor itself is a sealed unit. You cannot open it and fix internal parts. What technicians CAN do is repair the components connected to the compressor (relay, capacitor, wiring) or replace the entire compressor unit with a new one.
Symptoms That Point to Compressor Trouble
Not every cooling problem is a compressor problem. Before jumping to conclusions, check if you have these specific symptoms:
- Clicking sound every 2-3 minutes from the back — This is the most common sign. The relay is trying to start the compressor, failing, and retrying. The compressor itself might be fine — the relay could just be burned out.
- Compressor is completely silent and warm to touch — The compressor is not running at all. Could be a relay issue, capacitor failure, or a dead compressor winding.
- Compressor runs but fridge does not cool at all — The compressor is mechanically running but not pumping refrigerant. This usually means internal compressor failure.
- Loud humming or vibration from the compressor — Abnormal noise often indicates worn internal bearings or mounts. It might still work for now but is on borrowed time.
- Burning smell near the back of the fridge — Usually means the relay or start capacitor has burned out. Turn off the fridge immediately and call a technician.
Important: Many of these symptoms can also be caused by other issues like gas leakage or thermostat failure. Do not assume it is the compressor until a technician has properly diagnosed it with a multimeter and pressure gauge. We provide expert fridge compressor diagnosis in Dhaka at your doorstep.
Compressor Problems That ARE Repairable (Without Replacing the Compressor)
1. Burnt Relay Switch
The PTC relay is a small component attached to the side of the compressor. Its job is to provide the initial high-current boost to start the compressor, then disconnect. When it fails (which is very common in Dhaka due to voltage fluctuations), the compressor cannot start.
Cost: 500-1,200 BDT including labor
2. Failed Start Capacitor
The capacitor works alongside the relay to provide the starting torque. When it weakens or fails, the compressor hums but does not start, or starts very slowly.
Cost: 400-900 BDT including labor
3. Loose or Corroded Electrical Connections
In humid Dhaka conditions, the terminal connections on the compressor can corrode over years. This causes intermittent operation — the fridge sometimes works, sometimes does not.
Cost: 300-600 BDT including labor
4. Gas Starvation Due to Leak (Not a Compressor Problem)
Many people are told their compressor is bad when the real issue is a gas leak. Low refrigerant causes the compressor to overheat and shut off on thermal protection. Once gas is refilled, the compressor works fine again. If you are facing this, check our fridge gas refill service details.
Cost: 2,500-5,000 BDT (gas leak repair + refill)
When Replacement Is the Only Option
The compressor itself needs replacement when:
- Internal winding is open or shorted (confirmed by multimeter resistance test)
- Compressor mechanically locked — internal parts are seized and it will not turn at all
- Compressor valves are damaged — it runs but cannot build pressure
- Internal bearing failure causing excessive noise and vibration
Compressor replacement is a major job. It involves cutting the refrigerant lines, removing the old compressor, welding in the new one, replacing the filter drier, pulling vacuum, and recharging gas. This takes 3-5 hours and should only be done by experienced technicians.
Warning: Some low-cost technicians in Dhaka use “refurbished” or “reconditioned” compressors without telling you. These have a very high failure rate (often within 6 months). Always insist on a brand-new compressor with warranty. Ripon Refrigeration Works Ltd. only uses genuine new compressors.
Detailed Cost Breakdown (2025 Dhaka Rates)
| Job | Parts Cost | Labor | Total (BDT) |
|---|---|---|---|
| Relay replacement | 300-800 | 200-400 | 500-1,200 |
| Start capacitor replacement | 200-500 | 200-400 | 400-900 |
| Relay + capacitor (both) | 500-1,200 | 300-500 | 800-1,700 |
| Gas leak fix + refill | 1,500-3,000 | 1,000-2,000 | 2,500-5,000 |
| Compressor replacement (small 1/6 HP) | 5,000-8,000 | 2,500-4,000 | 7,500-12,000 |
| Compressor replacement (medium 1/5 HP) | 6,000-10,000 | 2,500-4,000 | 8,500-14,000 |
| Compressor replacement (large 1/4 HP+) | 8,000-15,000 | 3,000-5,000 | 11,000-20,000 |
Compressor Costs by Fridge Brand in Bangladesh
Compressor availability and pricing varies significantly by brand:
| Brand | Compressor Availability | Replacement Range (BDT) |
|---|---|---|
| Walton | Readily available | 7,000-12,000 |
| Singer | Readily available | 7,000-11,000 |
| Samsung | Available but pricier | 10,000-18,000 |
| LG (standard) | Available | 9,000-15,000 |
| LG (inverter) | Hard to find, expensive | 15,000-25,000 |
| Whirlpool | Moderate availability | 8,000-14,000 |
| Hitachi | Limited, may need import | 12,000-20,000 |
LG inverter compressors are particularly problematic — they are expensive, hard to source, and require specialized handling. If you own an LG inverter fridge, regular fridge repair and maintenance in Dhaka becomes even more important to protect this expensive component.
Repair vs Replace — The Decision Framework
Here is the honest framework I give my customers:
✅ Repair the compressor if:
The fridge is less than 8 years old, the body and insulation are in good condition, the brand still has parts availability, and the compressor replacement cost is less than 50% of a new fridge price.
❌ Replace the fridge if:
The fridge is more than 10 years old, the body has rust or insulation damage, it is a low-end brand with poor parts availability, the compressor cost exceeds 60% of new fridge price, or you have already spent significant money on previous repairs.
⚠️ Gray area — get honest advice:
Fridge is 8-10 years old, otherwise in decent condition. This is where a trustworthy technician’s opinion matters. At Ripon Refrigeration Works Ltd., we always tell customers honestly when we think replacement makes more sense, even if it means losing a repair job.

The compressor unit itself is sealed and cannot be opened for internal repair. However, the relay, capacitor, and wiring connected to it CAN be repaired, and these are the actual culprits in roughly 60% of “compressor problem” cases. True internal compressor failure requires full replacement.
Typically 3-5 hours for a standard fridge. The process involves cutting pipes, removing the old compressor, welding the new one, replacing the filter drier, pulling vacuum to remove moisture and air, and charging refrigerant gas. Rushing this job causes future problems.
Yes. Ripon Refrigeration Works Ltd. provides a 1-year warranty on new compressor installations. This covers both the compressor unit and the labor. If the same compressor fails within the warranty period due to manufacturing defect, we replace it at no additional cost.
We do not recommend it. Reconditioned compressors have unknown wear history and failure rates as high as 40-50% within the first year. The short-term savings (3,000-5,000 BDT less) are not worth the risk of paying for a second replacement soon after.
Turn off the fridge and unplug it immediately. Continued clicking attempts can overheat the relay further and potentially damage the compressor winding. Call a technician — in most cases this is just a relay replacement (500-1,200 BDT), but continuing to run it can turn it into a compressor replacement (8,000-18,000 BDT).
Yes, and this is one of the leading causes in Dhaka. Low voltage causes high current draw that burns the relay and capacitor. Voltage spikes during power restoration can damage compressor windings. A good voltage stabilizer is the best protection.
