Liebherr Wine Fridge Not Cooling Troubleshooting Guide
Before we dive into the possible causes and solutions, it’s important to note that wine fridges, like any other appliance, require regular maintenance to function effectively. Keeping your wine fridge clean, checking its components periodically, and addressing issues as soon as they arise will go a long way in ensuring its longevity and performance.
Now, let’s go over the potential reasons why your wine fridge is warm and what you can do to remedy the situation.
Faulty Thermostat
Another possible reason for your Liebherr wine fridge not cooling properly could be a faulty thermostat. The thermostat is responsible for regulating the temperature inside the fridge. If it’s not functioning correctly, the wine fridge won’t maintain the desired temperature.
To check if your thermostat is working correctly, you can use a thermometer to measure the temperature inside your wine fridge. If the temperature reading doesn’t match the thermostat setting, you might need to replace the thermostat. It’s best to consult your wine fridge’s manual for instructions on replacing the thermostat or contact a professional technician for assistance.

Dirty Condenser Coils
How do you fix a wine fridge that is not cooling? The most common fault in wine fridges is dirty condenser coils. The condenser is responsible for removing heat which cools the air inside your fridge. When the coils are dirty, they can’t dissipate heat effectively, resulting in your Liebherr wine fridge not cooling properly.
To resolve this issue, unplug your wine fridge and locate the condenser coils, typically found at the back or bottom of the unit. Carefully clean them with a soft brush and vacuum hose attachment, taking care not to damage the coils. After cleaning, plug your wine fridge back in and monitor its performance to see if the cooling issue has been resolved.
Blocked Air Vents and Fan Issues
Wondering “why is my Liebherr wine fridge fan not working?” It may be blocked air vents at fault. Debris and clogging in the air vents can lead to a Liebherr wine fridge not cooling properly. Blocked air vents can restrict airflow inside the fridge, making it difficult for the unit to maintain a consistent temperature. If the air vent isn’t clogged but no air is coming out, the fan might be stuck or broken. If the fan isn’t spinning, make sure it’s not stuck or blocked, and get it repaired or replaced if not.
To fix this issue, inspect the air vents in your wine fridge for any obstructions or debris. If you find any blockages, carefully remove them to allow for proper airflow. Make sure not to overfill your wine fridge, as this can also lead to blocked air vents and reduced cooling efficiency. If you notice the fan isn’t spinning, check that it isn’t blocked, if it’s not blocked it may need to be repaired or replaced.
Broken Evaporator
Why is my wine cooler running but not cooling? Ice buildup can damage your evaporator, another possible cause of your wine fridge not getting cold. To prevent damage, make sure your evaporator fan is free from ice particles and dust. If your evaporator is broken, it can be replaced, but you’ll need to ensure that the ice has fully melted before reinstalling a new fan. You may also notice a water leaking from fridge problem if this is the issue.

To speed up the melting process, place your wine cooler in a location with warm airflow. However, remember that plugging your wine cooler back in when there are still water particles inside can become a safety hazard and cause further electrical problems.
Issues With the Main Circuit System
Sometimes, a Liebherr wine fridge not cooling can be attributed to issues with the main circuit system. Electrical problems, such as damaged wiring or a faulty control board, can affect the fridge’s ability to cool effectively.
If you suspect that your wine fridge’s main circuit system might be the issue, you can first try resetting it. How do you reset a wine cooler? Some models can be reset by unplugging them for at least 5 minutes, give that a try and see if it solves the issue. If not, it’s best to contact a professional technician for assistance. Repairing or replacing electrical components can be dangerous if you don’t have the necessary skills and experience.
There are several reasons why your wine fridge won’t cool effectively. By identifying the cause and taking the appropriate steps to resolve the issue, you can get your wine fridge back to optimal performance in no time. Remember, if you’re ever unsure about tackling a repair yourself, it’s always best to call a professional like the fridge repair team at Kerenza Appliance.
