Bosch Refrigerator Freezer Not Freezing

There are so many reasons to choose a Bosch refrigerator and freezer. The options they make available really can make our life convenient. What can you do, however, when your refrigerator freezer is not working?

The most common reason why a Bosch refrigerator and freezer are not working is that the condenser coils are dirty. If you have coils that are exposed either under or behind the refrigerator, they should be cleaned regularly. Otherwise, they will not release heat and could cause the freezer to stop freezing.

There are also some Bosch refrigerators and freezers that do not have condenser coils that are exposed. They are included inside the walls of the refrigerator. If that is the case, they do not need to be cleaned regularly because they will not be exposed to the outside elements.

Bosch Refrigerator Freezer Not Cooling (How To Fix)

One feature to consider on any refrigerator and anytime you’re having difficulty is resetting the unit. Unfortunately, Bosch does not typically make it possible to do this with a single button, but there are ways to reset the unit easily.

If there is not a reset button included on the unit, which can be verified with the paperwork that came with the refrigerator, you can reset it by unplugging it.

Shutting the power off to the refrigerator is the first step in the process. Either unplug the refrigerator or turn off the circuit breaker to get this started. Make sure that you leave the power off to the refrigerator for at least five minutes.

You may wonder how this is any different than a simple power surge or other issues that cause the refrigerator to restart. In some cases, those quick restarts can actually be the problem.

The reason why you are letting the power off for at least five minutes is that you want the power to fully dissipate from all of the internal components. If you plug the refrigerator in too quickly, then some of the power may continue to be in the components and they will not fully restart.

After plugging in the refrigerator or turning on the circuit breaker, allow the refrigerator to fully restart. After it goes through the process, it should be reset. You can then check to see if the freezer is freezing or not.

Reasons Why Bosch Refrigerator Freezer is Not Freezing

A problem with the coils or needing to be reset are only some of the many different issues that can lead to this problem. Quite simply, if your freezer is not freezing, you’re going to have spoiled food very quickly.

Consider some of these factors that can cause your freezer to stop freezing. They are relatively easy to fix, or you can get a technician to fix them for you.

1. Evaporator Fan Motor

This is a part of the Bosch refrigerator and freezer that is often overlooked. It pulls air from the evaporator coils and pushes it into the freezer to circulate. If the fan is not running, the freezer will not be working.

One of the reasons why many people don’t know about the evaporator fan motor is that it does not operate when the freezer door is open. You can check it, however, by looking for the freezer door switch and manually activating it.

If you activate the manual door switch and the evaporator motor does not come on, you should remove the evaporator motor and check it for continuity with a multimeter. It’s a relatively easy item to replace. Just make sure that you turn the power off before working on any electrical components.

2. Condenser Fan Motor

This is similar to the evaporator fan motor but rather than pulling air from over the evaporator coils and circulating it in the freezer, it pulls air through the condenser and over the condenser coils. If it is not operating, you will not get cold air into the freezer.

You can check the condenser fan motor by accessing it and making sure that the blades are spinning. If it is not running, check to see if there is anything blocking the blades. You can also try spinning the blades with your finger.

If the blades are spinning properly, then you may have a problem with the fan motor bearings. Otherwise, it could be another issue with the fan or the motor.

While you have access to the motor, you may want to replace it and the fan at the same time. If it is not working, it is an issue that needs to be addressed.

Reasons Why Bosch Refrigerator Freezer is Not Cold Enough

Sometimes, the Bosch refrigerator freezer may get cold but it is not going to be cold enough. What are some of the reasons why this may occur?

1. Control Board

There may be times when you have a problem with the main control board and it has to be replaced. This is something that should be done if no other repairs fix the problem. You should check everything out carefully to ensure that it is actually the control board before you go ahead and replace it.

The problem is, if the main control board is faulty, you will not be able to test it with a multimeter to find out. What you can do, however, is to remove the control board and give it a good visual inspection.

Look for any problems with cracking on the control board or if any of the circuitry is burned. If that is the case, then you can try replacing the main control board and see if you get your Bosch refrigerator freezer up and running again.

2. Malfunctioning Thermostat

The thermostat is a very important part of the refrigerator. If it is not operating properly, then the control board is not going to know what the temperature is inside the freezer. There may even be times when the thermostat is telling the control board that the temperature is at an acceptable range when it actually isn’t.

The thermostat is a part of the refrigerator and freezer that is often replaced but it is also one that does not typically need to be replaced. You can check it with a multimeter to see if it is a problem. Replace the thermostat and you may find that your freezer is working again.

3. Faulty Door Switch

As we discussed earlier, the evaporator fan motor is not going to run unless the freezer door is closed. This can be a problem, because your freezer may think that the door is open when it is actually closed if the door switch is not working.

One thing you can do to check this is to try opening the freezer door and manually operating the door switch. If it is the part of the switch that can be operated in that way, then it may show itself to be a problem.

On the other hand, the door switch is a relatively inexpensive piece of equipment and it is also easy to replace. You can go ahead and replace it while you have the opportunity and see if it fixes the problem.

3. Condenser Coils

If the condenser coils are exposed, you should inspect them to make sure that they aren’t overly dirty. If the coils are dirty, you may not get the operation that you need in order to keep the freezer as cold as necessary.

The condenser coils should be cleaned on a regular basis, perhaps every six months or so. That being said, if the condenser coils are inside the unit and not exposed to the outside, they will not need to be cleaned.

Another problem that can sometimes happen with condenser coils is for the temperature to be off and for them to frost over. This is similar to what would happen to your home air conditioning unit. Once the frost starts forming, the cold air will stop blowing.

The way that you can fix this problem is to unplug the refrigerator and leave it unplugged for 24 hours. It can thaw out the condenser coils but then you need to find out why they got frosted over in the first place.

If you are going to leave your refrigerator unplugged for 24 hours, you’re going to lose the food in it. You have to monitor the temperature inside of the unit very carefully and if it gets too warm, the food will have to be thrown out.

4. Start Relay Problems

This little item may not often be spoken of, but it can be a problem that can keep your refrigerator from getting cold enough to freeze the freezer. It is a small relay kit that disconnects the starting capacitor in the motor from the winding circuit.

If the starter relay is going bad, the lights will be dimming, circuit breakers will trip frequently and you will probably hear a loud humming noise from the refrigerator. If that is the case, you can pull the motor and check the starter relay using a multimeter. Replace if necessary.

Anytime you are having a problem with your Bosch refrigerator freezer not freezing, you should check the condenser coils. If you can access them, make sure they are not frosted over and do not need cleaning. Otherwise, reset the refrigerator by unplugging it for five minutes.
