How to fix fridge compressor
Is your fridge compressor giving you trouble? You’re not alone. Many appliance owners in Durban face this issue. A faulty compressor can lead to spoiled food and rising electricity bills. But fear not! In this blog post, we’ll guide you through the steps to fix your fridge compressor.
-
1. Power Up
- Check if the fridge is plugged in securely and test the outlet with another appliance or a voltage tester.
- Check the breaker box for any tripped breakers or blown fuses.
-
2. Condenser Coil Cleaning
- The condenser fan helps dissipate heat and if it's not working correctly, the compressor could be overheating.
- Inspect the fan blades and replace the motor if necessary.

3. Condenser Fan Check-Up
- The condenser fan helps dissipate heat and if it's not working correctly,
- the compressor could be overheating.
Inspect the fan blades and replace the motor if necessary.

4. Evaporator Fan Inspection
Inside your freezer, the evaporator fan circulates cold air. If it's malfunctioning, this can impact your compressor. Check the fan blades for obstructions and ensure they spin freely. You will need to replace the motor if its faulty

5. Hit the Reset Button
Sometimes, a simple reset can work wonders. Unplug your fridge for 5-10 minutes to allow the control board to reset. This can often resolve minor glitches or issues caused by power surges.
-
6. Start Relay Scrutiny
The start relay, usually attached to the compressor, gives it the initial "push" to start. Remove it and give it a shake. If you hear a rattle, it's likely faulty and needs replacing. You can also use a multimeter to test it for continuity.

7. Overload Protector Assessment
this little device protects your compressor from overheating. If it's tripped, the compressor won't start. Find it near the start relay and test it with a multimeter for continuity. No continuity? Time for a new one.
-
8. Compressor examination
Use a multimeter to check the compressor windings for continuity, referring to the wiring diagram. If the readings are off, you might be facing a compressor replacement.
-
9. check for refrigeration leak
Refrigerant leaks can cause cooling inefficiency and strain the compressor. Carefully examine the refrigerant lines for any signs of damage, oil, or frost. Specialized leak detection kits can provide more accurate results. Remember: Handling refrigerants requires certification. If you suspect a leak, call a professional.
-
10. Thermostat Troubleshooting
The thermostat tells the compressor when to turn on and off. A faulty thermostat can lead to constant running or no running at all. Locate it (usually inside the fridge) and test it with a multimeter for continuity at different temperature settings. If it's not working correctly, it needs to be replaced.

2. how do I reset a fridge compressor?
- Unplug the Fridge: Disconnect it from the power source.
- Wait: Leave it unplugged for 5 to 10 minutes.
- Plug It Back In: Reconnect the power.
- Adjust Temperature Settings: Set your desired temperature.
- Monitor the Compressor: Ensure it starts running and check if the fridge cools down properly.
-
3. why cant I fix a fridge compressor myself?
it can be risky for plenty of reasons
- Complexity: Compressors involve intricate mechanics and require knowledge of refrigeration principles to diagnose and repair effectively.
- .Safety Hazards: Handling high-voltage electricity and refrigerants poses risks, including electric shock and environmental harm.
- Specialized Tools: Repair often requires specific tools that most homeowners may not have.
- Warranty Issues: DIY repairs can void your fridge’s warranty, which typically requires authorized service.
-
4. should a fridge compressor be hot?
A fridge compressor can feel warm during operation, which is normal, but it shouldn’t be excessively hot. Here are key points:
1.Normal Temperature: Compressors generate heat while running, so warmth is expected.
2.Excessive Heat: If it feels uncomfortably hot, it may indicate issues like insufficient airflow, a blocked condenser, or a failing component.
3.Cooling Off: After turning off, the compressor should cool down quickly; prolonged heat can signal malfunction.
