Title: Bosch Refrigerator B21Cl80Sns/01 Not Cooling

Have you ever experienced the frustration of opening your Bosch refrigerator, only to find that it’s not cooling? It’s a common issue that many people face, and it can be quite perplexing. In this article, we will delve into the possible reasons why your Bosch refrigerator model B21Cl80Sns/01 is not cooling and explore some troubleshooting steps to help you resolve the problem. So, grab a cold drink (from a working fridge, of course!) and let’s get started!

1. Understanding the Importance of a Cooling Refrigerator

Imagine a refrigerator as the heart of your kitchen, keeping your food fresh and safe to consume. It’s like a reliable companion that diligently maintains the optimal temperature to preserve your groceries. When it stops cooling, it can disrupt your daily routine and potentially lead to food spoilage. But fear not! Let’s uncover the potential culprits behind this cooling malfunction.

2. Check the Power Supply

Before diving into complex troubleshooting, it’s always a good idea to start with the basics. Ensure that your refrigerator is properly plugged into a functioning power outlet. Sometimes, a loose connection or a tripped circuit breaker can be the root cause of the cooling issue. Give the power supply a quick check to rule out any simple fixes.

3. Assess the Temperature Settings

Next, let’s take a look at the temperature settings on your Bosch refrigerator. It’s possible that the temperature control dial or digital display has been inadvertently adjusted, causing the cooling problem. Make sure that the temperature is set to the recommended level for refrigeration. Consult your user manual for specific instructions on adjusting the temperature settings for your model.

4. Clean the Condenser Coils

Over time, the condenser coils in your refrigerator can accumulate dust, debris, and pet hair, hindering the cooling process. To address this, locate the condenser coils (usually at the back or beneath the fridge) and gently clean them using a vacuum cleaner or a soft brush. Removing this buildup can significantly improve the cooling efficiency of your Bosch refrigerator.

5. Check the Evaporator Fan

The evaporator fan plays a crucial role in circulating cool air throughout the refrigerator. If it’s not working correctly, it can result in inadequate cooling. Open the freezer compartment and listen for the sound of the fan running. If you don’t hear anything, it may be a sign of a faulty fan motor. In such cases, contacting a professional technician for repair or replacement is recommended.

6. Inspect the Door Seals

Faulty door seals can lead to cool air leakage, causing your Bosch refrigerator to work harder to maintain the desired temperature. To check the integrity of the door seals, close the fridge door on a piece of paper or a dollar bill. If you can easily pull out the paper or bill without resistance, it’s an indication that the seals need to be replaced. Damaged door seals can be replaced with new ones readily available from appliance stores.

7. Examine the Air Vents

Blocked air vents can disrupt the airflow inside the refrigerator, resulting in uneven cooling or no cooling at all. Take a moment to inspect the air vents in both the freezer and refrigerator compartments. If you notice any obstructions like food items or ice buildup, clear them away to restore proper airflow. This simple step can often solve cooling issues.

8. Check the Defrost System

Bosch refrigerators are equipped with an automatic defrost system that prevents ice buildup on the evaporator coils. If this system malfunctions, it can lead to cooling problems. Check if the defrost heater, defrost thermostat, or defrost timer is faulty. If you suspect any issues with the defrost system, it’s advisable to seek professional assistance for diagnosis and repair.

9. Assess the Compressor

The compressor is the heart of your refrigerator’s cooling system. If it fails, your fridge won’t be able to cool effectively. Listen for any unusual noises coming from the compressor, such as clicking or buzzing sounds. Additionally, check if the compressor is vibrating or warm to the touch. These signs may indicate a malfunctioning compressor, and it’s best to consult a professional technician for further evaluation.

10. Call for Professional Help

If you have diligently followed the troubleshooting steps mentioned above and your Bosch refrigerator B21Cl80Sns/01 is still not cooling, it’s time to reach out to a qualified technician. They have the expertise and tools to diagnose and fix complex issues that may require specialized knowledge. It’s always better to be safe than sorry when it comes to your refrigerator’s cooling system.


A Bosch refrigerator not cooling can be a frustrating problem, but with a systematic approach to troubleshooting, you can often identify and resolve the issue. Start by checking the power supply and temperature settings, then move on to cleaning the condenser coils, inspecting the evaporator fan, examining the door seals, and clearing any blocked air vents. If these steps don’t solve the problem, it may be necessary to assess the defrost system or compressor. Remember, when in doubt, it’s best to seek professional assistance to ensure the longevity and optimal performance of your Bosch refrigerator. Stay cool and enjoy your fresh groceries!
