What To Know
- Dust and debris can accumulate on the coils, blocking airflow and causing the compressor to work harder, resulting in a humming noise.
- By following the troubleshooting steps outlined in this guide, you can identify the source of the humming in your Whirlpool refrigerator and take appropriate measures to resolve the issue.
- If the humming noise is coming from the compressor itself and it is running excessively, the compressor may need to be replaced.
If you’ve noticed an unusual humming noise coming from your Whirlpool refrigerator, you’re not alone. This is a common issue that can be caused by various factors. In this blog post, we’ll dive deep into the reasons why your Whirlpool refrigerator may be humming and provide step-by-step troubleshooting tips to help you resolve the issue effectively.
Identifying the Source of the Humming
Before you start troubleshooting, it’s important to identify the source of the humming. Here are some common components that may cause humming in a Whirlpool refrigerator:
- Compressor: The compressor is the heart of the refrigerator, responsible for circulating the refrigerant and maintaining the desired temperature. A faulty or worn-out compressor can produce a humming noise.
- Evaporator Fan: The evaporator fan circulates the cold air inside the refrigerator. A blocked or malfunctioning evaporator fan can cause a humming sound.
- Condenser Fan: The condenser fan is located at the back of the refrigerator and helps dissipate heat. A faulty condenser fan can also produce a humming noise.
- Thermostat: The thermostat controls the temperature of the refrigerator. A malfunctioning thermostat can cause the compressor to run excessively, resulting in a humming noise.
Troubleshooting Steps
1. Check the Power Source
Ensure that the refrigerator is properly plugged into a working power outlet. A loose or faulty electrical connection can cause humming.
2. Inspect the Condenser Coils
The condenser coils are located at the back of the refrigerator. Dust and debris can accumulate on the coils, blocking airflow and causing the compressor to work harder, resulting in a humming noise. Clean the coils with a vacuum cleaner or a brush.
3. Clean the Evaporator Fan
The evaporator fan is located inside the freezer compartment. Remove the freezer drawer and inspect the fan blades. If they are blocked by ice or frost, remove the ice and clean the fan blades with a soft brush.
4. Check the Compressor
The compressor is located at the bottom of the refrigerator. If it is making a humming noise, try to locate the source of the noise. If the noise is coming from the compressor itself, it may need to be replaced.
5. Inspect the Thermostat
The thermostat is located inside the refrigerator. If it is malfunctioning, it can cause the compressor to run excessively, resulting in a humming noise. You can test the thermostat by turning the temperature dial to a higher setting and listening for the compressor to turn off. If the compressor does not turn off, the thermostat may need to be replaced.
6. Check for Loose Components
Loose components, such as screws or bolts, can vibrate and cause humming. Inspect the refrigerator for any loose parts and tighten them as necessary.
7. Call for Professional Help
If you have tried the above troubleshooting steps but the humming noise persists, it is recommended to call a qualified appliance repair technician. They can diagnose the issue accurately and perform the necessary repairs.
Other Possible Causes
In addition to the common components mentioned above, other factors can also contribute to humming in a Whirlpool refrigerator:
- Defrosting cycle: The defrost cycle can produce a humming noise as the ice melts.
- Water line: A loose or damaged water line can vibrate and cause a humming noise.
- Ice maker: A malfunctioning ice maker can produce a humming noise.
Final Note: Resolving the Humming Issue
By following the troubleshooting steps outlined in this guide, you can identify the source of the humming in your Whirlpool refrigerator and take appropriate measures to resolve the issue. If the humming persists after trying the troubleshooting steps, it is advisable to consult with a qualified appliance repair technician for further assistance.
