Kenmore Refrigerator Making Loud Humming Noise

Introduction

A loud humming noise coming from your Kenmore refrigerator can be quite unsettling. While refrigerators are designed to make some noise, an unusually loud hum often indicates a problem that needs attention. This noise can be disruptive, especially if your kitchen is near living areas or bedrooms. More importantly, ignoring the noise could lead to reduced cooling efficiency or even a complete breakdown of your refrigerator. Therefore, it’s crucial to identify the source of the humming and address it promptly.

Common Causes of kenmore refrigerator making loud humming noise

Several factors can cause a Kenmore refrigerator to produce a loud humming noise. Here are some of the most common:. For more related activities, check out our Lg Refrigerator Water And Ice Dispenser Not Working.

• Condenser Fan Motor: This motor cools the condenser coils. If it’s failing or obstructed, it can hum loudly.
• Evaporator Fan Motor: Located inside the freezer, this fan circulates cold air. A failing motor can create a humming sound.
• Compressor: The compressor is the heart of the refrigerator, and a worn or failing compressor can produce a loud hum.
• Defrost Timer: This timer controls the defrost cycle, and a malfunctioning timer can cause a humming noise.
• Start Relay: This component helps start the compressor. A faulty start relay can lead to humming.
• Water Inlet Valve: If your refrigerator has an ice maker or water dispenser, a faulty water inlet valve can hum.
• Ice Maker: A stuck or malfunctioning ice maker can generate unusual noises, including humming.
• Dirty Condenser Coils: Dust and debris on the condenser coils can cause the refrigerator to work harder, leading to increased noise.
• Loose Components: Sometimes, components like the drain pan or tubing can vibrate against the refrigerator frame, causing a humming sound.

Symptoms Checklist

Use this checklist to help pinpoint the issue:

• Humming noise is constant.
• Humming noise is intermittent.
• Humming noise changes in pitch or volume.
• Refrigerator is not cooling properly.
• Freezer is not freezing properly.
• Ice maker is not working.
• Water dispenser is not working.
• Humming noise seems to be coming from the back of the refrigerator.
• Humming noise seems to be coming from inside the freezer.

How to Fix kenmore refrigerator making loud humming noise Step-by-Step Guide

Follow these steps to troubleshoot the humming noise:

1. Unplug the Refrigerator: Always disconnect the refrigerator from the power outlet before starting any troubleshooting or repairs.
2. Clean the Condenser Coils: Locate the condenser coils (usually on the back or bottom of the refrigerator). Use a vacuum cleaner with a brush attachment to remove dust and debris.
3. Inspect the Condenser Fan: Locate the condenser fan (usually near the compressor at the back of the refrigerator). Check for any obstructions like debris or ice. Ensure the fan blades spin freely. If obstructed, clear the blockage.
4. Inspect the Evaporator Fan: Open the freezer and locate the evaporator fan (usually behind a panel). Check for ice buildup or obstructions. If there is ice, manually defrost the freezer.
5. Listen to the Compressor: The compressor is located at the back of the refrigerator, near the bottom. Place your ear close to it and listen for the humming. Note the volume and consistency of the noise.
6. Check the Drain Pan: The drain pan catches water from the defrost cycle. Ensure it’s properly positioned and not vibrating against any other components.
7. Inspect the Water Inlet Valve (if applicable): Locate the water inlet valve (usually at the back of the refrigerator). Check for any leaks or signs of damage. Turn off the water supply to the refrigerator and inspect the valve.
8. Test the Start Relay (if comfortable): The start relay is usually attached to the compressor. This requires caution. After unplugging the refrigerator, visually inspect the start relay for any signs of burning or damage.
9. Check the Ice Maker (if applicable): Turn off the ice maker and listen to see if the humming stops. If it does, the ice maker may be the source of the noise.
10. Ensure Proper Leveling: Make sure the refrigerator is level. Use a level tool on the top of the refrigerator and adjust the leveling feet until it is level.
11. Check for Loose Components: Inspect the refrigerator for any loose panels, screws, or tubing that could be vibrating. Tighten or secure any loose parts.

Fix the Issue Without Buying Parts

Many times, the humming noise can be resolved without purchasing new parts:

• Refrigerator Reset: Unplug the refrigerator for 5-10 minutes and then plug it back in. This can sometimes reset the system and resolve minor issues.
• Deep Cleaning: Thoroughly clean the interior of the refrigerator, including all shelves and drawers. This can help eliminate any food particles or debris that might be contributing to the noise.
• Defrosting: Manually defrost the freezer to remove any ice buildup that could be affecting the fan or other components.
• Routine Maintenance: Regularly clean the condenser coils and check for any obstructions to ensure optimal performance and reduce noise.

When Replacement Might Be Necessary

If the humming noise persists after trying the troubleshooting steps, certain components might need replacement:

• Compressor: Compressor replacement is a major repair, and the cost can range from $400 to $800, including labor.
• Fan Motors: Condenser or evaporator fan motor replacement can cost between $100 and $300, including labor.
• Start Relay: A start relay replacement is a relatively inexpensive repair, costing between $50 and $150, including labor.

Safety Warning

Always prioritize safety when working with electrical appliances:

• Unplug the refrigerator from the power outlet before performing any maintenance or repairs.
• Avoid working on electrical components with wet hands or while standing on a wet floor.
• If you are uncomfortable working with electrical components, consult a qualified appliance repair technician.
