Why Do Side by Side Refrigerators Develop Problems?

Most refrigerator problems don't happen overnight. In many cases, they develop gradually because of everyday use, environmental conditions, or a lack of regular maintenance.

Understanding the common causes can help you prevent expensive repairs and keep your refrigerator operating efficiently for years.

Poor Maintenance

Dust, grease, and food residue can build up over time. Dirty condenser coils, clogged drain lines, and worn door seals force the refrigerator to work harder, reducing cooling efficiency and increasing electricity consumption.

Incorrect Temperature Settings

Many homeowners accidentally change the temperature without realizing it. A setting that's too warm can cause food to spoil, while one that's too cold may freeze fruits, vegetables, and dairy products.

Frequent Door Opening

Every time the refrigerator door is opened, warm air enters the cabinet. During Pakistan's hot summer months, frequent door opening makes the compressor run longer to maintain the desired temperature.

Overloading the Refrigerator

Packing shelves too tightly blocks airflow inside the refrigerator. Without proper air circulation, cooling becomes uneven, creating warm spots in some areas while freezing food in others.

Power Fluctuations

Voltage fluctuations and unexpected power outages can affect electronic components, especially in inverter refrigerators. Repeated power issues may eventually lead to sensor or control board faults.

Normal Wear and Tear

Components such as fans, door gaskets, thermostats, and compressors naturally wear out over time. Regular inspection helps detect these problems before they become serious.

Why Is My Side by Side Refrigerator Not Cooling Properly?

One of the most common complaints from refrigerator owners is poor cooling performance. If drinks aren't cold, vegetables lose freshness quickly, or frozen food begins to soften, your refrigerator isn't maintaining the correct temperature.

Before assuming there's a major fault, it's worth checking a few common causes.

Signs Your Refrigerator Isn't Cooling Properly

Watch for these warning signs:

• Food spoils sooner than expected.

• The refrigerator compartment feels warm.

• Weak or no cold airflow from the vents.

• Ice cream becomes soft.

• The compressor runs longer than usual.

• Ice cubes take longer to freeze.

Dirty Condenser Coils

Condenser coils release heat generated during the cooling process. When they're covered with dust and pet hair, heat cannot escape efficiently, forcing the refrigerator to work harder while reducing cooling performance.

Solution: 

Clean the condenser coils every six to twelve months using a soft brush or vacuum cleaner.

Incorrect Temperature Settings

Sometimes the simplest explanation is the correct one. If someone accidentally changes the temperature setting, your refrigerator may struggle to keep food fresh.

For most households, the refrigerator compartment should be set between 3°C and 5°C, while the freezer should remain around -18°C.

Blocked Air Vents

Cold air circulates through vents located inside the refrigerator. When large containers or tightly packed groceries block these vents, airflow becomes restricted.

Solution: 

Rearrange food items and leave enough space for air to circulate freely.

Damaged Door Gasket

The rubber gasket around the refrigerator door creates an airtight seal. If it's cracked, dirty, or loose, warm air continuously enters the refrigerator.

As a result, the compressor runs more often, cooling becomes inconsistent, and electricity usage increases.

Faulty Evaporator Fan

The evaporator fan distributes cold air throughout the refrigerator compartment.

If the fan stops working, one section of the refrigerator may remain cold while another becomes noticeably warmer.

A faulty fan usually requires replacement by a technician.

Compressor Problems

The compressor is the heart of the refrigerator's cooling system.

If it struggles to start, runs continuously without cooling, or stops working completely, professional diagnosis is recommended because compressor repairs require specialized equipment.

How to Fix Cooling Problems

Before calling a technician, try these simple troubleshooting steps:

• Check the temperature settings.

• Clean the condenser coils.

• Ensure the air vents aren't blocked.

• Inspect the door gasket for damage.

• Avoid overloading the refrigerator.

• Leave enough clearance behind the refrigerator for proper ventilation.

• Confirm that the refrigerator door closes completely after each use.

If cooling doesn't improve after these checks, the problem may involve the compressor, refrigerant, fan motor, or electronic control system.

When Should You Call a Technician?

Contact a refrigerator technician if:

• The refrigerator remains warm after basic troubleshooting.

• The compressor isn't running normally.

• The evaporator fan has stopped working.

• You hear repeated clicking sounds from the back of the refrigerator.

• The appliance displays an error code related to cooling.

Ignoring cooling problems can result in spoiled food and may cause additional damage to expensive components.

Why Is My Side by Side Refrigerator Freezing Food?

While poor cooling is a common complaint, freezing fresh food inside the refrigerator compartment is another issue many homeowners experience.

If vegetables turn into ice, milk develops ice crystals, or drinks become partially frozen, the refrigerator is likely operating below the recommended temperature or distributing cold air unevenly.

Fortunately, most freezing problems can be corrected without replacing the refrigerator.

Temperature Is Set Too Low

One of the most common reasons food freezes is an overly cold temperature setting.

Lower temperatures don't necessarily keep food fresher. Instead, they can damage fruits, vegetables, eggs, and dairy products.

Solution: 

Adjust the refrigerator temperature to 3°C–5°C and monitor it for the next 24 hours.

Food Is Blocking the Air Vents

Cold air enters through vents inside the refrigerator compartment.

When milk cartons, juice bottles, or large containers are placed directly in front of these vents, cold air is concentrated in one area, causing nearby food to freeze.

Solution: 

Leave space around the vents to allow cold air to circulate evenly.

Faulty Thermostat or Temperature Sensor

If the thermostat or temperature sensor sends incorrect readings to the control board, the compressor may continue cooling longer than necessary.

This often results in frozen food despite normal temperature settings.

A technician can test and replace faulty sensors if needed.

Air Damper Problems

The air damper regulates the amount of cold air moving from the freezer into the refrigerator compartment.

If it becomes stuck in the open position, too much cold air enters the fresh food section.

This usually requires inspection and replacement of the damper assembly.

Overfilling the Refrigerator

An overloaded refrigerator restricts airflow, creating cold spots where certain foods freeze while others remain at the correct temperature.

Organize groceries neatly and avoid blocking shelves or air passages.

Quick Solutions

If your refrigerator is freezing food, try these simple fixes:

• Increase the refrigerator temperature slightly.

• Keep fruits and vegetables away from cold air vents.

• Rearrange food to improve airflow.

• Avoid overloading shelves.

• Check that the thermostat is working correctly.

• Monitor the temperature for 24 hours after making adjustments.

If food continues freezing despite these steps, the refrigerator may have a faulty thermostat, air damper, or temperature sensor that requires professional repair.

Why Is Water Leaking from My Side by Side Refrigerator?

Finding water on the kitchen floor can be frustrating, but it doesn't always mean your refrigerator has a serious fault. In many cases, the leak is caused by a clogged drain, a loose water connection, or excess condensation that can be fixed with a few simple checks.

Before calling a technician, inspect the following areas to identify the source of the leak.

Clogged Defrost Drain

During the automatic defrost cycle, melted frost flows through a drain hole into a collection tray beneath the refrigerator.

If the drain becomes blocked by food particles or ice, the water has nowhere to go and begins collecting inside the refrigerator or leaking onto the floor.

Solution: 

Flush the drain with warm water and remove any visible blockage.

Loose or Damaged Water Filter

Many side by side refrigerators include a built-in water filter for the dispenser and ice maker.

If the filter isn't installed correctly or has reached the end of its service life, small leaks may develop around the filter housing.

Solution: 

Remove and reinstall the filter properly. Replace it if it's damaged or overdue for replacement.

Cracked Water Supply Line

A damaged water line supplying the ice maker or water dispenser can slowly leak behind or underneath the refrigerator.

Check the water line for visible cracks, loose fittings, or signs of moisture.

Ice Maker Leak

A faulty ice maker or overflowing ice tray can allow water to escape into the freezer compartment before dripping onto the floor.

Inspect the ice maker for damaged components or excessive ice buildup.

Excess Condensation

During humid weather, especially in summer, moisture may collect around the refrigerator door if it's opened frequently or doesn't seal properly.

While a small amount of condensation is normal, excessive moisture usually indicates warm air is entering the refrigerator.

Step-by-Step Inspection

If your refrigerator is leaking water, follow these checks:

• Inspect the drain hole for blockages.

• Check the water filter installation.

• Examine the water supply line for leaks.

• Look behind the refrigerator for signs of moisture.

• Inspect the door gasket for gaps.

• Confirm the refrigerator is standing level.

DIY Fixes

Many leaks can be resolved without professional repairs.

• Clean the defrost drain regularly.

• Replace damaged water filters.

• Tighten loose water connections.

• Replace cracked water hoses.

• Clean and inspect the door gasket.

• Avoid leaving the refrigerator door open for long periods.

If water continues leaking after these steps, the problem may involve an internal water valve or another component that requires professional service.

Why Is My Side by Side Refrigerator Making Noise?

A refrigerator is never completely silent. Fans, compressors, and the automatic defrost system all produce sounds during normal operation.

The key is knowing which sounds are expected and which could indicate a developing problem.

Humming

A gentle humming sound is usually produced by the compressor while it's cooling the refrigerator.

Normal: Yes.

Buzzing

A brief buzzing noise may occur when the compressor starts or when the ice maker fills with water.

If the buzzing becomes unusually loud or continuous, it could indicate a compressor or electrical issue.

Clicking

Occasional clicking is often caused by the thermostat or control board switching the compressor on and off.

Repeated clicking without the compressor starting may point to a faulty start relay or compressor.

Rattling

Loose shelves, bottles, or containers can create rattling sounds when the compressor is running.

Pull the refrigerator slightly away from the wall and ensure nothing is vibrating against the cabinet.

Fan Noise

The evaporator and condenser fans circulate air throughout the refrigerator.

If the fan blades become obstructed by ice or debris, you may hear scraping or grinding sounds.

Compressor Noise

Compressors naturally make more noise during hot weather because they operate for longer periods.

However, loud knocking or metallic sounds should be inspected by a technician.

Which Noises Are Normal?

These sounds are usually part of normal operation:

• Light humming

• Soft clicking

• Gentle airflow

• Occasional buzzing

• Water dripping during the defrost cycle

Which Noises Require Attention?

Arrange an inspection if you hear:

• Loud grinding

• Repeated clicking without cooling

• High-pitched squealing

• Knocking sounds

• Continuous rattling after checking loose items

Why Is the Ice Maker Not Working?

An automatic ice maker is one of the most convenient features of a side by side refrigerator. When it suddenly stops producing ice, the cause is often easier to fix than many homeowners expect.

Common Causes

Water Supply Problems

If the water supply valve is closed or the household water pressure is too low, the ice maker won't receive enough water to produce ice.

Frozen Fill Tube

The water tube supplying the ice maker can freeze, preventing water from reaching the ice tray.

Carefully thawing the tube usually restores normal operation.

Dirty Water Filter

A clogged water filter restricts water flow and reduces ice production.

Most manufacturers recommend replacing the filter every six months.

Low Water Pressure

Insufficient water pressure prevents the ice maker from filling correctly.

If both the water dispenser and ice maker are affected, the home's water supply should also be checked.

Faulty Ice Maker Assembly

If all other components are working correctly, the ice maker itself may have developed an electrical or mechanical fault.

Professional diagnosis is recommended.

Troubleshooting Checklist

Before requesting repairs:

• Confirm the water supply valve is fully open.

• Check the water filter.

• Inspect the fill tube for ice.

• Ensure the ice maker is switched on.

• Empty old ice from the storage bin.

• Restart the refrigerator if necessary.

Why Is My Side by Side Refrigerator Running Continuously?

It's normal for a Side by Side Refrigerator to run more often during hot weather or after you've added a large amount of fresh food. However, if the compressor runs almost all day without stopping, it may indicate an issue that's affecting cooling efficiency and increasing electricity consumption.

Identifying the cause early can help prevent unnecessary wear on the compressor and reduce your energy bills.

Common Reasons

Hot Summer Temperatures

During Pakistan's summer, ambient temperatures can exceed 40°C. In these conditions, the refrigerator naturally runs for longer periods to maintain the set temperature.

This is normal as long as the refrigerator is cooling properly.

Frequent Door Opening

Every time the refrigerator door is opened, warm air enters the cabinet. The compressor must then work harder to restore the desired temperature.

Try to keep the door closed as much as possible, especially during hot weather.

Dirty Condenser Coils

Dust-covered condenser coils cannot release heat efficiently. As a result, the compressor runs continuously while cooling performance gradually decreases.

Cleaning the coils every six to twelve months helps improve efficiency.

Worn Door Gasket

A damaged or loose door seal allows warm air to enter continuously.

This forces the refrigerator to cool the cabinet repeatedly, causing the compressor to run for longer than necessary.

Inspect the gasket for cracks, gaps, or dirt buildup.

Poor Ventilation

A refrigerator requires enough space around the back and sides to release heat.

If it's installed too close to a wall or inside a tightly enclosed cabinet, airflow becomes restricted.

Leave the manufacturer's recommended clearance around the appliance.

Defrost System Problems

Modern refrigerators automatically remove frost from the evaporator.

If the defrost heater or sensor fails, ice builds up around the evaporator coils, making the compressor work harder to maintain cooling.

When Is Continuous Running Normal?

Continuous operation is generally normal when:

• The refrigerator has just been installed.

• A large quantity of warm food has been added.

• The room temperature is very high.

• The doors are opened frequently.

If the refrigerator runs continuously even during cooler weather and cooling performance starts to decline, it should be inspected by a technician.

Why Does My Refrigerator Smell Bad?

Unpleasant odours don't always come from spoiled food. Moisture, bacteria, blocked drains, and food spills can all create persistent smells inside the refrigerator.

Regular cleaning keeps food fresh and prevents unpleasant odours from developing.

Common Causes

Expired Food

Forgotten leftovers, spoiled vegetables, and expired dairy products are among the most common sources of bad smells.

Check stored food regularly and remove expired items promptly.

Spilled Liquids

Milk, juice, sauces, and other liquids can seep beneath shelves and drawers if they aren't cleaned immediately.

These spills encourage bacterial growth over time.

Blocked Drain

A clogged defrost drain may collect stagnant water, creating unpleasant odours.

Cleaning the drain periodically helps prevent this issue.

Dirty Shelves and Drawers

Food residue trapped beneath shelves or inside vegetable drawers gradually produces unpleasant smells.

Clean removable parts with warm water and mild detergent.

Mold Growth

Excess moisture inside the refrigerator can encourage mold growth, particularly around door seals and hidden corners.

Dry the interior thoroughly after cleaning.

Natural Ways to Remove Odours

Instead of using strong chemical cleaners, you can naturally freshen the refrigerator by:

• Cleaning the interior regularly.

• Removing expired food immediately.

• Wiping spills as soon as they occur.

• Placing an open box of baking soda inside the refrigerator.

• Keeping the drain hole clean.

• Allowing air to circulate by avoiding overcrowded shelves.

Common Side by Side Refrigerator Error Codes

Many modern refrigerators include a self-diagnostic system that displays an error code whenever it detects a problem.

These codes help identify faults before they become more serious.

Some common examples include:

• Fan Error – Indicates a problem with the evaporator or condenser fan.

• Defrost Error – Suggests the automatic defrost system isn't operating correctly.

• Temperature Sensor Error – The refrigerator is receiving incorrect temperature readings.

• Communication Error – Electronic components are unable to communicate properly.
