Electrolux Refrigerator Not Cooling? Key Parts to Check (Complete Detailed Guide)
When an Electrolux refrigerator stops cooling, the disruption is immediate. Food spoils, interior temperatures rise, and you’re left wondering whether the appliance needs a simple adjustment or a major repair. Fortunately, most cooling problems can be traced to a specific set of causes. Understanding how the refrigerator’s cooling system works and the role of each component allows you to diagnose the problem more confidently.
This guide explains every key part involved in cooling, why the refrigerator stops cooling, and what each symptom means. The explanations are intentionally detailed, so homeowners can understand not only what to check but also why these parts matter.
Understanding How Cooling Works in an Electrolux Refrigerator
Before inspecting parts, it is useful to understand the basic cooling cycle. A refrigerator doesn’t “produce” cold air; instead, it removes heat. Electrolux refrigerators rely on a closed-loop system consisting of a compressor, coils, fans, sensors, and a control board. When any component fails, the cooling system becomes unstable.
1. How the Compressor Drives the Cooling System
The compressor is the heart of the system. It pressurises the refrigerant and pushes it through the condenser coils. When the compressor is functioning correctly, it maintains steady pressure so the refrigerant can travel throughout the refrigerator.
A weak or failing compressor cannot generate enough pressure, causing the fridge to lose cooling gradually. Sometimes, a compressor struggles to start because of a faulty start relay rather than its own failure. Because the compressor is part of the sealed system, diagnosing it properly is crucial.
2. How Refrigerant Absorbs and Releases Heat
Refrigerant circulates through two sets of coils:
- Condenser coils release heat to the outside environment.
- Evaporator coils absorb heat from inside the refrigerator and freezer.
3. The Role of Airflow in Cooling Both Compartments
Refrigerators rely on constant airflow, achieved through fans and vents. The freezer is typically the source of cold air, and the refrigerator section depends on air being drawn from the freezer through an air damper.
Any obstruction, whether due to frost, blocked vents, or fan failure, can cause noticeable temperature differences between compartments.
Initial Checks Before Inspecting Internal Components
Before opening panels or testing internal parts, it’s important to start with simple, external checks. Many refrigerator cooling issues are caused by settings, airflow restrictions, or power-related problems rather than failed components. Performing these basic inspections can save time, prevent unnecessary repairs, and often restore normal operation quickly. Only after these checks are completed should internal components be examined.
1. Checking Temperature Settings
Incorrect temperature settings frequently cause cooling problems. The refrigerator section should be set between 37–40°F, and the freezer should sit between 0–5°F. If the settings are too high, the compressor will not run often enough. If the settings are too low, ice buildup may occur, blocking airflow and preventing cooling in the refrigerator section.
2. Ensuring the Refrigerator Has Power
Sometimes, partial power loss leads to the refrigerator lights turning on while cooling components remain off. Check the plug, outlet, and breaker panel. Unstable voltage or a loose plug can interrupt the cooling cycle. Once power is restored, the compressor may take several minutes to restart.
3. Examining the Door Gaskets for Air Leaks
Door gaskets must create an airtight seal. If they become cracked, dirty, or loose, warm air enters the refrigerator. This forces the compressor to work harder while the interior temperature rises. Carefully run your fingers along the seal and look for gaps. If the gasket doesn’t grip the frame tightly, cold air escapes and cooling problems occur.
4. Checking for Blocked Air Vents
Electrolux refrigerators rely on free airflow between the freezer and refrigerator compartments. Large items pressed against vents prevent cold air from circulating. When airflow is disrupted, the freezer may remain cold while the refrigerator warms. Organising items to keep vents clear often restores normal temperature.
5. Resetting the Refrigerator’s Control System
Unplugging the refrigerator for ten to fifteen minutes resets the control board. This can correct minor software errors or sensor misreadings that stop cooling. After reconnecting power, allow several hours for temperatures to stabilise.
Detailed Component Checks When the Refrigerator Still Doesn’t Cool
1. Condenser Coils: How Dirty Coils Cause Cooling Failure
Condenser coils play a major role in heat removal. When refrigerant travels through these coils, it releases heat absorbed from inside the refrigerator. If the coils are covered with dust, pet hair, or grease, they cannot release this heat effectively. As heat accumulates, the refrigerant cannot cool properly, and the refrigerator begins to warm.
Dirty coils force the compressor to run longer and harder, often leading to premature wear. You can usually locate the coils either on the back of the fridge or beneath it. Cleaning them regularly helps maintain efficient cooling and reduces energy consumption. When coils are extremely dirty, cooling problems become immediate and severe.
2. Condenser Fan: Why Airflow Around the Compressor Matters
Placed near the condenser coils is the condenser fan. Its purpose is to move air across the coils and help release heat from the compressor. When the fan stops working, heat accumulates rapidly. Even if the coils are clean, a non-functioning fan prevents proper heat exchange.
A failing condenser fan often results in both the refrigerator and freezer warming simultaneously. The back of the refrigerator may feel unusually hot. Sometimes, the fan becomes clogged with debris, but in many cases, the motor itself fails. If the refrigerator’s compressor is running yet the fan remains still, immediate repair is required to prevent overheating.
3. Evaporator Fan: Essential for Circulating Cold Air Inside the Refrigerator
Inside the freezer compartment is the evaporator fan. This fan circulates cold air across the evaporator coils and distributes it through the refrigerator and freezer. If the evaporator fan stops, the freezer may stay cold near the coils, but the refrigerator section will warm significantly.
Unusual sounds such as squealing, grinding, or rattling often indicate that the evaporator fan motor is beginning to fail. In some cases, frost buildup prevents the fan blades from spinning. Since the fan is responsible for moving cold air out of the freezer, a non-operational evaporator fan frequently results in a situation where the freezer is functional but the refrigerator is not.
4. Evaporator Coils: How Frost Buildup Stops Cooling Completely
Evaporator coils absorb heat from the refrigerator. These coils become extremely cold during operation and naturally collect small amounts of frost. The defrost system melts this frost at regular intervals. When the defrost system stops working, frost accumulates rapidly and forms thick layers of ice.
This ice blocks airflow, restricts the evaporator fan, and prevents cold air from reaching the refrigerator section. You may notice ice forming inside the freezer or hear a fan hitting ice. While unplugging the refrigerator and allowing the ice to melt temporarily restores airflow, the frost will return unless the faulty defrost component is replaced. This component may be the defrost heater, thermostat, or the control board managing defrost cycles.
5. Air Damper: Regulating the Flow of Cold Air Into the Refrigerator
The air damper controls how much cold air enters the refrigerator from the freezer. It opens when the refrigerator needs cooling and closes when the desired temperature is reached. If the damper becomes stuck closed, the refrigerator will not receive enough cold air, even if the freezer remains cold. Conversely, if it becomes stuck open, the refrigerator may become excessively cold.
A malfunctioning air damper often causes inconsistent temperatures in the refrigerator section. You may also hear a clicking sound as the damper motor attempts to move but cannot complete the motion. Inspecting the damper provides insight into whether it is functioning properly or restricting airflow.
6. Thermistor: The Temperature Sensor That Controls Cooling Cycles
A thermistor continuously measures temperature and sends this information to the control board. If the thermistor sends inaccurate readings either too warm or too cold the control board will make incorrect decisions about when to run the compressor and fans.
A faulty thermistor can cause unpredictable temperature fluctuations. The refrigerator may cool excessively at some times and not cool enough at others. If all mechanical components appear functional, the thermistor should be inspected next. Diagnosing a thermistor requires checking electrical resistance at specific temperatures.
7. Start Relay: Why the Compressor Sometimes Fails to Start
The compressor cannot start on its own. It needs the start relay to provide a jolt of electricity that initiates the cooling cycle. When the start relay fails, the compressor either does not start or starts briefly and then shuts off. A classic symptom of relay failure is repeated clicking from the back of the refrigerator.
Replacing a start relay is simpler and less costly than replacing a compressor. Many cooling issues mistakenly attributed to compressor failure turn out to be relay problems.
8. Compressor: Understanding When the Most Critical Component Fails
The compressor pressurises refrigerant and circulates it through the system. If it fails, the refrigerator will lose cooling entirely. A failing compressor may make humming sounds, become excessively hot, or fail to run even with a new relay. Because the compressor is part of the sealed system, only trained technicians with proper certifications can diagnose and replace it.
If the refrigerator is older than ten years, compressor replacement may not be cost-effective. Understanding the age and condition of the appliance helps determine the best approach.
9. Refrigerant Leak: A Serious Issue That Cannot Be Ignored
A refrigerant leak slowly reduces cooling capacity. Unlike mechanical failures, a leak usually causes gradual temperature loss rather than sudden failure. The evaporator coils may develop an uneven frost pattern, and the compressor may run continuously without achieving the correct temperature.
Refrigerant leaks require specialised equipment and cannot be repaired by homeowners. A certified technician must identify the leak, repair the tubing, and recharge the system.
When You Should Call a Professional Technician
It is time to call a technician when:
- The compressor does not run despite replacing the start relay.
- The evaporator coils show an uneven frost pattern.
- Frost returns quickly after manual defrosting.
- There is no airflow despite functional fans.
- You suspect refrigerant loss or sealed system issues.
Why OEM Parts Matter When Repairing an Electrolux Refrigerator
When repairing an Electrolux refrigerator, choosing OEM (Original Equipment Manufacturer) parts is essential for long-term performance and reliability. OEM components are designed specifically for Electrolux models, ensuring they match the exact specifications, fit, and functionality of the original parts. Unlike generic replacements that may vary in size, material, or electrical compatibility, OEM parts integrate seamlessly with the appliance’s cooling system and control board. This reduces the risk of improper installation, repeated breakdowns, or voided warranties. Using OEM replacements ensures consistent cooling performance, maintains safety standards, and extends the lifespan of your refrigerator, making them the most dependable choice for any repair.
Preventive Maintenance to Avoid Cooling Problems
Maintaining your Electrolux refrigerator reduces the likelihood of failure. Cleaning condenser coils every six to twelve months, ensuring door gaskets remain flexible and intact, keeping internal vents clear, and avoiding overloading shelves all help ensure consistent cooling.
An Electrolux refrigerator that stops cooling can be diagnosed through a systematic examination of basic functions, airflow, and key components. Most issues begin with dirty coils, obstructed airflow, or minor part failures rather than major sealed system problems. Understanding how each component works allows you to identify the cause quickly and decide whether the repair is manageable or requires a technician.
