Marcus Hayes Key Takeaways
- Airflow blockage is the most common cause of cooling failure in Asko units.
- A dirty condenser coil forces the compressor to run constantly and overheat.
- Temperature sensor faults can cause the fridge to stop cooling entirely.
- Compressor failure requires certified professional service due to high voltage.
The Bottom Line
Most Asko cooling issues stem from blocked airflow or a dirty condenser. Check these simple items first. If the problem persists, a certified technician must diagnose sensor or compressor faults.
Why Asko Refrigerators Stop Cooling
When your Asko refrigerator starts running warm, it feels like an emergency. You have perishables inside, and the temperature is climbing. In my experience, the cause is rarely a broken compressor right away. It is usually something simpler that you can check without opening the panel.
ASKO designs its appliances for efficiency and longevity. That means the cooling system is precise. If one small thing goes wrong, the whole system struggles. You need to look at airflow, the condenser, and the sensors.
Before you worry about a major repair, do these five checks. They take about fifteen minutes. If none of them solve the problem, it is time to call a professional. Trying to fix a sealed refrigerant system yourself is dangerous and can void your warranty.
1. Check for Blocked Airflow
This is the number one issue I see. Asko fridges use a multi-flow cooling system. Air circulates through vents in the back or sides of the fridge. If you pack the shelves too tightly, you block that air.
Walk up to your fridge. Look at the back wall.
Are your bottles or containers touching it? If so, the cold air cannot circulate. The compressor runs harder to compensate, but the shelves stay warm.
Move things around. Leave space between items and the back wall. Also, check the freezer vents.
If ice has built up and blocked them, the air cannot move from the freezer to the fridge. If you see ice buildup, turn the unit off for a few hours to let it melt. This is a safe DIY step. Just unplug the unit first to be safe.
2. Inspect the Condenser Coils
The condenser coils are the black or metal grids behind or under your fridge. They release heat from the system. If they get dusty, they cannot release heat. The compressor has to work much harder.
Here is the thing: if the compressor runs constantly and never stops, it is often because the coils are dirty. The unit is trying to cool down, but it cannot dump the heat. This leads to overheating and eventual failure.
You can check this easily. Look behind the fridge. If the coils are covered in thick dust or pet hair, that is your problem.
A technician can clean these thoroughly, but you can also use a vacuum hose to remove loose dust if you are careful. Do not bend the fins. If the coils are deep behind a panel, leave that to a pro. It is safer and they have the right tools.
3. Look for Temperature Sensor Issues
Modern Asko fridges have temperature sensors. These small parts tell the control board how cold the unit is.
If a sensor fails, it sends the wrong signal. The board might think the fridge is cold when it is actually warm. Or it might think it is too cold and stop cooling when it needs to cool down.
You might notice the fridge is warm, but the freezer is fine. Or both are warm, but the compressor is not running. That points to a sensor or control board issue.
You cannot fix a sensor yourself. It requires opening the interior panel and testing the electrical resistance. That is a job for a certified tech.
If you have ruled out airflow and dirt, this is likely the next suspect. A technician will use a multimeter to check the sensor values. If it is out of range, they will replace it.
4. Listen to the Compressor
The compressor is the heart of the fridge. It pumps the refrigerant.
It is usually at the bottom back of the unit. It should hum quietly. If you hear a loud click, a buzz, or silence, something is wrong.
If the compressor is not running at all, the fridge will not cool. This could be a start relay failure or a bad compressor. If it is running but the fridge is still warm, the refrigerant might be low.
Low refrigerant is a sealed system issue. Only an EPA-certified technician can handle refrigerant. Do not try to open the lines. It is dangerous and illegal to vent refrigerant without certification.
If the compressor is making unusual noises or not starting, stop using the fridge. Unplug it. Call a professional. Continuing to run a faulty compressor can cause a complete failure that is much more expensive to fix.
When to Call a Technician
You should call a professional if:
- The fridge is still warm after checking airflow and cleaning accessible coils.
- You hear strange noises from the compressor.
- The compressor is not running.
- You suspect a refrigerant leak (oil spots near the bottom back, or the fridge is very warm but the freezer is okay).
- You are not comfortable removing panels or testing electrical components.
Using an independent tech does not void your warranty under the Magnuson-Moss Warranty Act. The manufacturer would have to prove that the repair caused the problem. But using a certified technician ensures the work is done correctly and safely.
Asko appliances are built to last. Many of our customers have units that are over 20 years old. Getting the right diagnosis is key to keeping your appliance running for years to come. A quick diagnostic visit can save you from a major breakdown later.
Preventative Maintenance Tips
To avoid cooling problems, do these things every few months:
- Check the seals: If the door seal is torn or not sticking, cold air escapes. Wipe it with a warm damp cloth. If it is damaged, replace it.
- Keep it level: The fridge should be slightly tilted backward. This helps the doors close properly and prevents air leaks.
- Don't overpack: Leave space for air to flow. Use baskets or organizers to keep items away from the back wall.
- Clean the coils: Vacuum the condenser coils every six months if you can access them. If they are behind a panel, have a tech clean them annually.
These small habits save money and keep your food safe.
How Much Does Asko Refrigerator Repair Cost?
Costs vary by the specific problem and the age of the unit. Here is a general breakdown:
| Issue | Typical Cost Range | DIY Possible? |
|---|---|---|
| Blocked Airflow | Free | Yes |
| Dirty Condenser Coils | ~$75 - $150 | Yes (if accessible) |
| Temperature Sensor | ~$200 - $350 | No |
| Compressor Start Relay | ~$150 - $250 | No |
| Compressor Replacement | ~$600 - $1000+ | No |
These are estimates. Get a written quote before any major repair. Sometimes, if the fridge is very old, it might not be worth repairing. A technician can advise you on that.
Frequently Asked Questions
Why is my Asko fridge warm but the freezer is cold?
This is usually an airflow problem. The air from the freezer is not moving into the fridge section. Check the vents in the freezer.
If they are blocked by ice or food, clear them. If that does not work, the fan motor or damper might be stuck. That requires a professional.
Can I clean the condenser coils myself?
Yes, if they are accessible from the back or under the fridge without removing a panel. Use a vacuum or a coil brush. If the coils are behind a rear panel, it is safer to have a technician do it. You might damage the fins or the refrigerant lines.
How long do Asko refrigerators last?
With proper maintenance, Asko refrigerators often last 15 to 20 years or more. Many units are still running after 25 years. Regular cleaning and airflow checks help extend their life.
Is it worth repairing an old Asko fridge?
Often, yes. Asko appliances use high-quality parts that are still available.
If the repair cost is less than half the cost of a new unit, it is usually worth it. But if the compressor failed and the unit is over 15 years old, you might want to consider replacing it. Ask your technician for their advice.
What should I do if the fridge makes a loud clicking sound?
Turn it off and unplug it. The clicking is likely the compressor trying to start and failing. Continuing to run it can damage the compressor. Call a technician to check the start relay or the compressor itself.
