A refrigerator that is not cooling is not necessarily a major failure. In most cases, the issue is related to airflow or the defrost system rather than a critical component.
Compressor failures, often seen as the most serious, account for about 10% of cases. Even when there is no cooling at all, the cause can still be linked to a simpler component.
In many situations, especially for appliances under 10 years old, a fridge repair is possible and worth considering.
At Service 2000, our technicians respond every day across the Montreal and Quebec City regions. With experience, certain symptoms become recognizable patterns that quickly point to a diagnosis. Before concluding there is a breakdown, here is how to read the situation clearly and systematically.
Key Takeaways
- A fridge that isn’t cooling isn’t always a major breakdown: airflow and defrost issues are often the cause.
- If the freezer works but the fridge is warm, cold air usually isn’t circulating properly.
- Frost buildup, a blocked fan, or a faulty thermostat are common causes.
- Compressor failures represent a minority of cases, at around 10%.
- For a refrigerator under 10 years old, repair is often worth considering before replacement.
- If the temperature keeps rising, the motor is struggling, or unusual noises appear, a prompt diagnosis is recommended.
What Are the Most Common Causes When a Fridge Stops Cooling?
These internal statistics help better understand what is actually happening in real-world situations.
About 30%¹ of cases are associated with the presence of water, such as a fridge leaking or dripping underneath. This is not directly a cooling issue, but rather a sign that the defrost system or drain is not functioning properly. Over time, this ends up affecting the circulation of cold air.
In nearly 28% of situations, the freezer continues to work but the fridge becomes warm. This is a very common scenario. Cold air is being produced, but it is no longer circulating to the right section, often due to a ventilation issue or ice buildup.
Around 23% of cases involve a complete loss of cooling, both in the fridge and the freezer. This usually points to a more global system failure that requires a more in-depth intervention.
Conversely, about 14% of situations involve excessive cooling, where food freezes in the refrigerator section. This type of issue is often linked to poor temperature regulation.
Other more occasional cases, such as unusual noise, excessive ice, or irregular operation, complete the picture. While less frequent individually, they are still important to consider.
Finally, issues related to the compressor represent a minority of cases, around 10%. Most interventions are instead related to airflow, defrosting, or temperature control. In many situations, especially for appliances under 10 years old, repair is a worthwhile and effective option.
¹ Based on more than 10,000 service calls carried out by Service 2000 technicians between 2021 and 2025, clear patterns emerge when a refrigerator stops cooling.
What Should You Check First When Your Refrigerator Stops Cooling?
1. Check the Power Supply
A loose plug, a tripped breaker, or an electrical fluctuation can stop the cooling entirely. It is a basic check, but it resolves more cases than one might expect.
2. Check the Thermostat Setting
An incorrect setting can easily be mistaken for a breakdown. The thermostat may have been adjusted without anyone noticing. Returning it to a normal setting and waiting a few hours can help confirm whether this is the issue.
For food safety reasons, a refrigerator should be kept at 4°C (40°F) or below, according to the Government of Canada.
3. Check Whether the Air Vents Are Blocked
Cold air is produced in the freezer and then circulated into the fridge. If food is blocking the vents, airflow becomes restricted. This is a common cause of a warm fridge with a functioning freezer.
4. Check the Door Seals
Worn or damaged gaskets allow warm air to enter continuously. The refrigerator works harder but cannot maintain a stable temperature. This issue is often visible to the naked eye.
It is also worth noting: a faulty door seal allows moisture to enter, which condenses and frosts over on the evaporator. Over time, this buildup can block airflow and undermine the defrost system.
5. Check for Frost Buildup
Excessive ice accumulation blocks airflow and reduces cooling performance. If frost is visible, especially at the back of the freezer or along the walls, it may explain the loss of efficiency.
Important: defrosting manually may give the impression the problem is solved. But if the underlying cause, a defective defrost system, is not addressed, the frost will return, and so will the problem.
6. Check the Condenser Ventilation
The condenser and ventilation grilles, located at the back or underneath the refrigerator, can accumulate dust over time. Buildup reduces cooling efficiency. It is recommended to clean these exterior vents regularly and to ensure that airflow around the condenser and compressor is not obstructed.
What Signs Indicate a Real Refrigerator Breakdown?
The Motor Is Running, But the Fridge Is Not Cooling
This is a frequent scenario. The system is operating, but can no longer produce or distribute cold air effectively. The issue is typically internal (airflow, defrost function, or a component such as the motor or the compressor).
In practice, this type of symptom almost never resolves on its own.
The Fridge Is Making Noise or Seems to Be Struggling
Unusual noise often signals that a component is working abnormally. It could be a fan blocked by ice, or a system forcing itself to maintain temperature.
On models with a mechanical relay, a repetitive clicking sound can sometimes be heard when the relay overheats and stops functioning properly.
When noise increases at the same time as cooling drops, that is rarely a good sign.
The Refrigerator Is Cooling, But Not Enough
A fridge that partially cools is often in the early stages of decline. Airflow or temperature regulation is becoming ineffective, and the situation tends to worsen. It can also point to an early refrigerant leak, which limits the system’s ability to exchange heat properly even when the compressor is still running.
At that point, acting quickly often prevents a complete breakdown.
When Should You Call an Appliance Repair Technician in Quebec?
If the basic checks resolve nothing after a few hours, it is better to act.
Concretely, it is time to call when:
- the motor runs continuously without result
- the fridge becomes warm despite a cold freezer
- unusual noises appear
- the temperature continues to rise
- food begins to be at risk
In these situations, waiting generally resolves nothing and may worsen the breakdown.

Repair or Replace a Fridge That Stopped Cooling?
The Age of the Refrigerator
As a general rule, a refrigerator under 10 years old is usually well worth repairing. Beyond that, the decision depends more on its overall condition.
The Type of Failure
Some repairs are straightforward and long-lasting. Others involve major components. The key question is always whether the repair will hold over time.
When Repair Is Still Worth It
If the appliance is in good condition overall and the failure is specific, repairing it is often the better choice. Consumer Reports notes that a refrigerator under 10 years old is generally more economical to repair than to replace.

What Should You Prepare Before Calling to Get Your Fridge Repaired in Quebec?
Before calling, it helps to have:
- the model number of the appliance
- a clear description of the problem
- when the issue first appeared
- observed symptoms (noise, temperature, ice, etc.)
The more precise the information, the more efficiently the technician can act from the very first visit.
FAQ – My Fridge Stopped Cooling
Why is my fridge not cooling but the freezer works?
This is one of the most common patterns. Cold air is being produced but is no longer reaching the fridge compartment. In the field, this is often linked to an airflow or defrost issue.
Why is my fridge not cooling but the motor is running?
The system is attempting to operate but can no longer do so effectively. An internal component is typically at fault. This may involve the motor itself, the compressor, or another element of the cooling circuit.
Why is my fridge making noise and not cooling?
Unusual noise combined with a loss of cooling often means a part is malfunctioning or under strain. Together, these symptoms almost always call for a technician.
What should I do if my fridge is not cooling enough?
Start by checking the settings and the airflow. If the problem persists, it is rarely just a minor adjustment.
Does unplugging a refrigerator reset it?
It can resolve a minor electronic glitch, but it will not fix a mechanical problem or a cooling system failure.
How do I know if the thermostat is faulty?
If the fridge does not respond to setting changes or maintains an inconsistent temperature, the thermostat may be defective.
How do I know if the compressor is the problem?
If there is no cooling at all and the compressor does not start or makes an abnormal noise, it may be the cause. This is a more complex repair to assess.
Is it worth repairing an older fridge?
When the appliance shows significant wear or is nearing the end of its lifespan, replacement may be the more practical option. But every situation deserves its own evaluation.
