Side By Side Refrigerator Not Cooling

Introduction

A refrigerator that’s not cooling properly is a major problem. It can lead to spoiled food, wasted money, and a lot of frustration. If your side-by-side refrigerator isn’t maintaining the proper temperature, it’s important to address the issue quickly to prevent food spoilage. This guide will walk you through common causes and troubleshooting steps to help you diagnose and fix the problem yourself.

Common Causes of side by side refrigerator not cooling

Here are some of the most common reasons why your side-by-side refrigerator might not be cooling:

Dirty Condenser Coils: Dust and debris on the condenser coils restrict airflow, making the refrigerator work harder and less efficiently.
Blocked Vents: Items blocking the vents inside the refrigerator and freezer can prevent proper air circulation.
Faulty Door Seals: Worn or damaged door seals allow warm air to enter, causing the refrigerator to struggle to maintain a cool temperature.
Overloaded Refrigerator: Packing too much food inside can restrict airflow and prevent even cooling.
Incorrect Temperature Settings: Make sure the temperature settings are properly adjusted.
Frost Buildup in the Freezer: Excessive frost can block airflow from the freezer to the refrigerator compartment.
Faulty Start Relay: Start relay helps the compressor to start and run. If it’s faulty, the compressor may not start, and the refrigerator will not cool.
Damper Problems: The damper controls how much cold air flows from the freezer to the refrigerator. If it’s stuck closed, the refrigerator won’t cool.
Compressor Issues: The compressor is the heart of the cooling system. If it’s failing, the refrigerator won’t cool properly.
Evaporator Fan Motor Failure: This fan circulates cold air within the freezer and to the refrigerator section. If it fails, airflow will be reduced or stopped.

Symptoms Checklist

Use this checklist to accurately identify the problem:

The refrigerator compartment feels warm.
The freezer compartment is working normally.
The freezer compartment is also warmer than usual.
You hear the refrigerator running, but it’s not cooling.
You don’t hear the refrigerator running at all.
There’s excessive frost buildup in the freezer.
The refrigerator is making unusual noises.
The door seals appear damaged or cracked.
The motor sound coming from the back is unusually loud.

How to Fix side by side refrigerator not cooling Step-by-Step Guide

Follow these steps to troubleshoot your refrigerator:

Check the Temperature Settings: Make sure the temperature settings for both the refrigerator and freezer are set correctly. Consult your owner’s manual for the recommended settings.
Clean the Condenser Coils: Unplug the refrigerator. Locate the condenser coils (usually on the back or bottom of the unit). Use a vacuum cleaner with a brush attachment to remove dust and debris.
Check for Blocked Vents: Ensure that the vents inside the refrigerator and freezer are not blocked by food items. Rearrange items to allow for proper airflow.
Inspect the Door Seals: Check the door seals for any damage, cracks, or gaps. Clean the seals with warm, soapy water and a soft cloth. You can also try applying a thin layer of petroleum jelly to the seals to improve their seal.
Defrost the Refrigerator: If there’s excessive frost buildup in the freezer, manually defrost the refrigerator. Unplug it and leave the doors open for several hours until the frost melts. You can place towels inside to absorb the water.
Check the Evaporator Fan: Open the freezer door and listen for the evaporator fan running. If you don’t hear it, the fan motor may be faulty. Visually inspect the fan for any obstructions.
Listen to the Compressor: The compressor is located at the back of the refrigerator. Listen to see if it’s running. If it is, but the refrigerator isn’t cooling, the compressor might be failing. If it’s not running, check the start relay.
Check the Start Relay: Locate the start relay on or near the compressor (usually a small black box). Unplug the refrigerator. Carefully remove the relay and shake it. If it rattles, it might be faulty and may need replacing (though we aren’t recommending that as the first step).
Inspect the Damper: The damper controls the airflow between the freezer and refrigerator compartments. Locate the damper (usually in the refrigerator compartment near the top). Make sure it’s opening and closing properly. If it’s stuck, it might need to be manually adjusted or replaced.
Check the Overload Protector: Another component associated with the compressor, sometimes located next to start relay. Make sure it’s in good condition.
Avoid Overpacking: Make sure the refrigerator isn’t overloaded with food. Overpacking can restrict airflow.
Check the Power Outlet: Ensure the refrigerator is properly plugged into a working outlet. Test the outlet with another appliance.
Reset the Refrigerator: Unplug the refrigerator for 10-15 minutes, then plug it back in. This can sometimes reset the system and resolve minor issues.
Check Ice Maker Settings: If you have an ice maker, ensure it is turned on and functioning correctly. Problems with the ice maker can sometimes affect overall refrigerator cooling.

Fix the Issue Without Buying Parts

Before you consider replacing any parts, try these free methods:

Refrigerator Reset: As mentioned above, unplugging the refrigerator for 10-15 minutes can often resolve minor glitches.
Thorough Cleaning: A clean refrigerator operates more efficiently. Clean spills promptly and wipe down interior surfaces regularly.
Temperature Recalibration: Some refrigerators have a recalibration function. Consult your owner’s manual for instructions.
Regular Maintenance: Clean the condenser coils every 6 months and inspect the door seals regularly to prevent future problems.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and your refrigerator still isn’t cooling, the compressor or evaporator coil might be the culprit. Replacing these parts can be expensive, potentially costing between $300 and $700, depending on the refrigerator model and the cost of labor. If your refrigerator is old (over 10 years), it might be more cost-effective to replace the entire unit. Common failing parts include: Compressor, Start Relay, Evaporator Fan Motor, Damper Control.

Safety Warning

Always unplug the refrigerator before performing any maintenance or repairs.
Avoid working on electrical components if you’re not comfortable or experienced.
Be careful when handling tools to avoid injury.
Keep the area around the refrigerator dry to prevent electrical shock.
If you’re unsure about any step, consult a qualified appliance repair technician.

Tools You May Need

Screwdrivers (Phillips and flathead)
Vacuum cleaner with a brush attachment
Soft cloth
Warm, soapy water
Multimeter (optional, for testing electrical components)

FAQ

Here are some frequently asked questions about refrigerators that aren’t cooling:

Q: Why is my freezer cold, but my refrigerator is warm?
A: This is often caused by a blocked damper or a faulty damper motor.
Q: How often should I clean the condenser coils?
A: It’s recommended to clean the condenser coils every 6 months.
Q: What temperature should I set my refrigerator to?
A: The ideal refrigerator temperature is between 37F (3C) and 40F (4C).
Q: What does it mean if my refrigerator is making a clicking sound?
A: A clicking sound could indicate a problem with the start relay or the compressor.
Q: Is it normal for the sides of my refrigerator to feel warm?
A: Yes, it’s normal for the sides of the refrigerator to feel warm, as this is where the condenser coils are located.

Conclusion

Troubleshooting a side-by-side refrigerator that’s not cooling can seem daunting, but by following these steps, you can often diagnose and fix the problem yourself. Remember to prioritize safety and consult your owner’s manual for specific instructions. If you’ve exhausted all troubleshooting options and the issue persists, it might be time to call a qualified appliance repair technician.
