Bosch Refrigerator Not Cooling. When you open your refrigerator door and it’s not cold enough, you might assume something is wrong with the power source.
While this can cause your refrigerator to run hot, remember that you have access to controls that allow you to modify the temperature inside.
The problem might be something as easy as setting a slightly higher temperature than normal so that your food remains at an ideal state of coolness.
Fixing a Bosch refrigerator may be much simpler than some people anticipate; we provide our readers with quick tips for diagnosing and fixing common problems in order for them to make the process go by more smoothly.
Bosch Refrigerator Not Cooling
If your refrigerator is not working properly, you might have to clean the condenser coils. Cleaning the coils can fix a lot of issues with refrigerators.
First of all, ensure that the filters are not clogged and then check to see if there is more dust or dirt on top. Clear out any dust and you’ll need to spend about one hour cleaning the condenser coils.
In this article, we discuss some problems with Bosch refrigerators when they don’t cool.
Fan For Evaporator
An evaporator fan, also known as a cooling evaporator fan, is like a propeller-like device used inside your refrigerator or freezer.
It’s meant to help circulate the cold air inside and prevent temperature fluctuations that might cause the perishable food you store in the refrigerator to spoil quickly.
A faulty evaporator fan might not be able to do its job properly, causing your refrigerator or freezer compartments to remain warm instead of staying cool.
To fix this problem, you must first remove the mounting clip that holds the fan in place by using pliers to pull it out firmly. Then dismantle the fan by removing its fan blades and wire harness from the old part before installing them onto the new one.
Replacing The Door Gasket
The rubber gasket on your refrigerator door creates a seal that prohibits cold air from escaping and warm air from entering.
However, if this seal is dirty or damaged, the refrigerator door won’t close properly and you’ll notice that your Bosch refrigerator is warm.
If you have determined that the gasket is deteriorating quickly, you can test its integrity in order to determine whether or not it should be replaced.
Put a dollar bill halfway into the door. Pulling the bill out with resistance indicates that the gasket is still working properly. Trust us when we say that this is going to cause problems in the long run even though it seems like a quick fix now.
Defective Main Control Board
The main control board might be defective, but this is almost never the case. It’s much more likely there are other components that have gone bad instead.
To narrow down which component is most likely to be responsible for the fault, first make sure all of the other components haven’t been damaged or broken by testing them individually.
If none of these components cause the problem then it may be time to replace the main control board as a last resort.
Error In Thermistor
In a refrigerator, the thermistor is like one of those fancy light switches that you find on top of the door.
It sends temperature readings to the control board, which tells everything from the compressor to the evaporator fan – what it needs to do and when.
If you notice your refrigerator isn’t cooling too well, it could be that your thermistor has gone bad. To determine if your model needs a new one, use a multimeter to check its resistance.
The reading should change as you adjust room temperature. If the thermistor doesn’t have continuity or resistance, then it may be faulty and needs replacing.
Control Board For Temperature
The temperature control board is the unit that sends a signal to make sure the cooling refrigerator is working appropriately, if this control board isn’t sending a signal then it can’t do its job.
When you get the temperature control board you’ll need to test it by measuring the voltage at the input and output wires with a voltmeter.
If there’s no signal, then your temperature control board won’t work properly. It’s important to note that misdiagnosing what’s wrong with your cooling device often happens before replacing a faulty temperature control board so make sure you fully check for other problems.
Relay Start Cause
The start relay works in conjunction with the start winding to begin the compressor- located in the evaporator coil. If the start relay is defective, this may prevent your refrigerator from getting cold enough in certain settings.
The fix is to determine if there’s continuity between the run and start terminal sockets of the relay by testing it with a multimeter.
If there isn’t continuity, then your new part will be a replacement for your old one. In addition, if you are experiencing a burnt odor from the relay, you will want to replace it as well.
Fan Motor For Condenser
The condenser fan sucks air through the condenser coils and over the compressor. If the condenser fan doesn’t work, your fridge won’t cool properly.
To find out if the fan is broken, check underneath it to see if any of its blades are blocked. Next, take its blades and try spinning them by hand if they don’t spin easily, the motor needs replacing.
If everything looks ok underneath, use a multimeter to check whether it can handle electricity. If it can’t pass an electric current, replace the fan motor.
