Bosch Refrigerator Not Cooling? 10 Easy Fixes To Try

Are you having a hard time getting your Bosch refrigerator to cool down? Then take a look at 10 reasons why this happens and what you can do to repair your white good.

The most common reasons for a Bosch fridge to stop cooling are that the plug socket or fuse doesn’t work, the condenser coils need cleaning, it needs repositioning, it’s overloaded, and its door gaskets need cleaning. 

But how can you work out which of these problems is wreaking havoc with your fridge? Take a look at the following section of this article. There we will discuss the reasons why your refrigerator isn’t cooling and what you should do to fix it.

10 Ways to Fix a Bosch Refrigerator That Isn’t Cooling Properly

Bosch fridges are known to have cooling issues from a variety of common issues. In general, try a quick reset by pulling the plug for 5 minutes. If that doesn’t work, the lack of cooling might be due to being set up incorrectly, or due to a faulty component.

Let’s cover each of them, one by one.

#1 Check Your Plug Socket

Let’s get cracking with some of the more straightforward things to fix that should get your Bosch refrigerator cooling again. Here’s how you should begin:

  1. Check that your power cord is intact and that you have plugged your refrigerator in properly. Does the power cord show signs of damage? Then you will need to replace it. 
  2. Test the power socket with another electrical appliance. You can use any appliance such as a kettle or hairdryer for this task. If the power socket does not work, you will have to get an electrician to repair it. In the meantime, move the fridge to a working power source.

#2 Ensure the Fuse Works

Another super simple job to do is to ensure that your fuse in the plug works. If it doesn’t your fridge will not stay cool. Here are two ways that you check this:

  1. Take the fuse out of your Bosch refrigerator’s plug and put it into another appliance
  2. Remove the fuse from your Bosch refrigerator’s power plug. Put a new fuse in its place. 
    1. NOTE: You should only use 13 amp fuses in your Bosch fridge’s power plug

#3 Adjust Your Temperature

If your home is anything like mine, the fridge is one of the most frequently used appliances in the house (after the TV of course). The kids are in and out of it all day and it is constantly being opened, closed, and brushed past. With all of that, it would be so easy to knock and alter the temperature control. This could be the reason why your Bosch refrigerator is too warm.

To fix this issue, simply set your refrigerator to the right temperature. Here’s what you need to know:

  • You should set your fridge to 4°C (40°F)
  • You should set your freezer to -18°C (0°F)

#4 Clean the Condenser Coils

The condenser coils on the back of your Bosch fridge need to be kept clean. When they are covered in dust and dirt, it forces the fridge to work harder. When the coils are very dirty, it may be difficult for your fridge to stay cool. 

So what should you do to fix this problem? Cleaning the dust and dirt off of the condenser coils is key. Here are two ways that you can do that:

  1. Use a vacuum brush head tool to clean over and in between the coils. A brush head with bristles will work best for this.
  2. Use a dusting cloth to wipe the dust and dirt away from the condenser coils
    1. NOTE: To keep your fridge in the best working order, you should complete this job periodically

#5 Avoid Sunlight and Heat

Your Bosch refrigerator will also have a tough time keeping cool if it has a lot of heat surrounding it. If your fridge is in direct sunlight or next to a hot appliance, it will find it harder to remain cold. This is especially the case during the warm, summer months. Here’s what you can do to keep your Bosch refrigerator from overheating:

  • Keep it out of direct sunlight
  • Keep it away from hot appliances such as ovens or even radiators

#6 Keep It Away From the Wall

Like all of us, your Bosch refrigerator needs a little room to breathe. It likes its own space. That’s why, if it is nestled against a wall or other appliances, it may struggle to stay cool. This is how you should position your fridge:

  • Keep it at least 1 inch from the wall behind it
  • Keep it at least 1 inch from other appliances on either side of it

#7 Do Not Overload It

None of us like being overworked, and your Bosch refrigerator feels exactly the same. When you overload it, you disrupt the airflow inside the appliance. Overstocking your fridge could also cause you to block the air vent. 

Here are some tips that will help you to keep your fridge clear:

  • Stock your fridge ⅔ full
  • Revise the contents of your fridge weekly and remove anything that has passed its use-by date

#8 Clean the Door Gaskets

Your Bosch refrigerator doors are the barrier between the warm environment outside and the fresh and cool air inside. If your door gaskets are loose, they will begin to let in warm air. If the door gaskets are dirty, they will also begin to filtrate warm air into your fridge. 

When warm air filtrates inside your fridge it will be forced to work harder. Most modern fridges can put up with this. But if you have a slightly older Bosch fridge it might struggle to stay as cool as you would like it to.

To stop this from happening, do the following:

  1. Replace loose gaskets
  2. Clean dirty gaskets

#9 Replace the Faulty Start Capacitor

The capacitor gives a ‘boost’ of power to the compressor when you start it up. If the capacitor is faulty, the compressor may not start. To check the operation of the start capacitor, test it with a multi meter. If there is no continuity in the reading, you will need to replace it.

#10 Replace the Faulty Temperature Control Board

If the temperature control board is faulty, it won’t be sending voltage to the cooling system. 

Before you consider replacing the whole board, check all of the most commonly defective components first, this will save you time and money as boards can be easily misdiagnosed.  Either test the board yourself if you’re skilled in electronics, or contact your nearest Bosch retailer to do this for you.
