Noisy Refrigerator & Not Cooling? Expert Fixes Inside
The refrigerator is one of the most important appliances in the home. It’s frustrating when it starts making loud noises and stops working properly. If your refrigerator isn’t cooling and is also making strange noises, it likely has a problem and needs repair. In this article, we’ll examine the most common problems that can cause refrigerator noises and prevent it from cooling correctly, how to try to fix them yourself, and when it’s necessary to contact a professional repair service.
Refrigerator making noises and not cooling properly.
Is your refrigerator making noise and not cooling? Common causes, troubleshooting, and professional solutions.
1. Dirty or Blocked Condenser Coils
Dust and dirt can gradually accumulate on the condenser coils, blocking airflow and causing the refrigerator to work harder than necessary to cool properly. This can lead to overheating, poor cooling performance, and even strange noises, such as humming or rattling.
Solution:
– Locate the condenser coils (they are usually found at the back or bottom of the refrigerator).
– Using a vacuum cleaner or a coil cleaning brush, carefully remove the dust and dirt every 6 to 12 months.
2. Defective Evaporator or Condenser Fan Motor
Refrigerators use fans to circulate air and control the temperature. If the evaporator fan (in the freezer) or the condenser fan (near the compressor) is malfunctioning, you may hear loud noises such as clicking, humming, or squeaking. A faulty fan can also cause uneven cooling or prevent the refrigerator from cooling properly.
Solution:
– Open the freezer and listen for any change in the sound with the door open. If the noise stops, the problem is likely the evaporator fan.
– If the noise is coming from the back of the refrigerator, use a vacuum cleaner to carefully clean the condenser fan and remove any dust or debris that may be obstructing it.
– You will likely need a professional technician to repair or replace the part.
3. Compressor Issues:
The compressor is the engine of your refrigerator, responsible for keeping it cold. If you hear a loud buzzing or knocking noise, this indicates a faulty compressor. If your refrigerator is warm while the compressor is running, the cause could be a low refrigerant level or another major mechanical failure.
Solution:
– You might hear clicking sounds, which indicate a faulty start relay (the part that starts the compressor).
– Have a technician inspect the compressor if it is overheating or not functioning properly.
– A broken compressor will usually need to be replaced by a professional.
4. Defective Start Relay or Capacitor
A clicking sound and insufficient cooling in your refrigerator usually indicate a failure in the start relay or capacitor. These parts help the compressor start, and if they malfunction, the refrigerator will not cool properly.
Solution:
– If you unplug the refrigerator and hear a rattling sound, you can listen to the start relay to check if it’s burned out.
– If it is defective (as sometimes happens), a new relay will restore the refrigerator to normal operation.
5. Malfunctioning Defrost System
A refrigerator has a defrost system to prevent ice buildup. If the defrost heater, thermostat, or timer fails, the refrigerator will continue to make noises and won’t cool properly, as excessive frost buildup blocks the airflow.
Solution:
– First, unplug the refrigerator and check if the start relay shows any signs of burning or is making strange noises.
– Check for frost buildup inside the freezer.
– If there is a thick layer of ice, the defrost system may not be working correctly.
– If any of the components of the defrost system are faulty, a technician can diagnose the problem and replace the defective part.
6. Water Valve or Ice Maker Problems:
If your refrigerator has a water dispenser or ice maker, a faulty water valve can produce a buzzing or similar noise. A clogged water line can also cause the ice maker to malfunction or leak.
Solution:
-Inspect the water supply connection and check the supply valve for any obstructions.
-If it’s dirty, clean or replace the water filter.
