If your Bosch freezer is not doing its job properly, it truly can end up causing a calamity in the kitchen.
Luckily, you’ve come to the right place to get help fixing your beloved Bosch appliance.
In the following article, we’ll take you through a few simple ways to fix a Bosch freezer that’s no longer working the way it should.
Safety warning: Remember to always unplug your freezer from its power source before beginning any repair work. Failure to do so may result in injury from electric shock or damage to your appliance.
Next, you’ll want to check the evaporator coils of your freezer to see if they’re dirty or covered in frost.
If there is any frost or ice accumulated on them, then you need to thaw them out by defrosting your freezer.
In general, it’s a good idea to defrost the freezer whenever there’s a buildup of ice which exceeds 7mm in thickness. Some freezer’s will have an automatic defrost system, but if yours doesn’t then you’ll need to defrost it manually.
Evaporator coils covered in frost will not be able to accomplish their task of releasing cold air for the fan to circulate around the freezer. The effect of this is that the freezer will fail to get adequately cold.
The first most common culprit of a freezer not freezing effectively, is debris build-up on the condenser coils, which are usually located either behind or under the appliance.
Have a look to see if they’re dirty. If they are, use a vacuum or a cloth to get them clean. We usually recommend that you clean them at least every 6 months to ensure your freezer functions properly.
The role of the condenser coils is to dissipate heat which passes through them before condensing it. If they are dirty, then they won’t be able to complete this task and consequently, the freezer won’t be able to cool.
If you’re a savvy handyman or handywoman, there’s no harm in testing your freezer’s components for continuity.
However, if you don’t have the tools or knowledge of how to do this, it’s best to leave this types of tests and diagnosis toa trained appliance professional.
The evaporator motor in your freezer is there to circulate cool air in the freezer.
To find out whether or not this component is faulty, you’ll need to first unplug your appliance, then locate the evaporator fan and attempt to turn the fan blade manually. You should be able to rotate the fan without any resistance.
If it puts up some resistance, then it is defective and will need to be replaced.
Also, if you notice the motor is making an unusual noise during operation, this is also a sign that it likely needs to be replaced.
Likewise, a condenser fan motor contributes to the active cooling process of your freezer as it draws cold air through the condenser and keeps the inside of the appliance chilled.
After locating your condenser fan, try turning the blades of the fan by hand.
Once again, if they don’t turn easily, then it is likely that the motor bearings are worn out and will need to be replaced.

By feeding temperature readings to the control board, the thermostat informs the fan motors and the compressor whether or not to run and cool down the unit.
If the thermostat is faulty and unable to do this, then the fans nor the compressor will not function correctly and the freezer will fail to cool, or it might cool down too much.
To check if your thermostat is working properly, you might try setting the thermostat and then using a working thermometer to see if the temperatures match up. If not, it’s a good sign that either the unit’s temperature sensor or the thermostat are defective.
The defrost heater assembly and control board determine how often the freezer will run the defrost cycle.
If any of these components fails, then the freezer will not be able to carry out the defrost cycle causing frost to continue to build up and obstruct the evaporator coils.
This, as we’ve already established, makes it difficult for the freezer to remove heat.
The defrost timer switches on the defrost heater at various points during the day in order to melt any accumulated frost off of the evaporator coils.
If the defrost timer is not working, then the defrost heater will fail to turn on when needed.
This means frost will accumulate on the evaporator coils and prevent them from working.
With that being said, if any of your defrost heater assembly’s components are not working properly, you’ll likely run into some issues with your appliance.
But to determine whether or not this assembly is working, as well as which components are at fault, you’ll need to use a multimeter to test for continuity.
If you’ve tried all these troubleshooting tips and you’re still having no luck getting your freezer to cooperate, don’t hesitate to contact Denver Appliance Repair.
