Why Does My Bosch Fridge Freeze Food

Your Bosch fridge may be freezing your food because of the following reasons:

i. The temperature of your fridge is too low.

ii. There isn’t enough food in the fridge.

iii. A component of your fridge may be faulty.

Below is a list of Bosch fridge components that, when faulty, can make your fridge freeze your food…

1. Thermistor

The work of the thermistor, which is a sensor in the refrigerator, is to read the air temperature of the fridge and send this reading to your fridge’s control board. According to the reading, the control board regulates the evaporator fan and compressor.

A faulty thermistor may read the air temperature inaccurately or may not function at all. Due to this, the control board will not normally regulate the evaporator fan and compressor. And they may run more frequently than they should and then cause the fridge’s temperature to be too cold.

2. Temperature Control Thermostat

This directs power to the evaporator fan and compressor. If your fridge’s temperature control thermostat becomes faulty, it may result in the entire system running longer than it should. This will make the fridge too cold and begin to freeze.

3. Damper

The damper allows cold air to enter the refrigerator. It opens and closes periodically to regulate the amount of cold air that goes into the fridge. If the damper gets broken, it may stay open and cold air will pour into the fridge nonstop.

This will make the fridge too cold, and your food may begin to freeze. You must open the fridge and locate the damper in the top part of the fresh food section. Inspect it to see if it is stuck open; that should explain the excess cold air freezing the food. If that is the case, replace the damper or have a technician do the job.

4. Temperature Control Board

The temperature control board provides the voltage that the cooling system needs to run. So, a faulty control board may send voltage to the fan motors and compressor continuously, making the fridge too cold to the point of freezing food.

However, control boards hardly fail, and they are easy to misdiagnose. Therefore, you must check other components that are more likely to fail before touching or replacing the control board.

You must also check the condenser coils. If they are significantly dirty, the dirt insulates the coils and prevents them from dissipating heat from the fridge. Consequently, the compressor runs all the time to maintain a cool temperature. Cleaning the coils every six months or every year is crucial to prevent this from happening. So, use a vacuum cleaner to remove the dirt from the coils and release the trapped heat.

How to Check If the Components Are Faulty

Each component that may be responsible for making the fridge freeze foods has to be checked. You have to do this so that the problem can be isolated and solved. We will therefore discuss how to check these components for faults…

1. Thermistor

To check if the thermistor is faulty, you will need a multimeter. Since the thermistor reads the fridge’s temperature, its resistance should be the same as the fridge’s temperature.

While checking the thermistor’s resistance with the multimeter, change the temperature of the fridge. If the thermistor resistance does not change as the fridge’s temperature, then it is bad and needs replacing.

2. Temperature control thermostat

Turn the thermostat from the lowest point to the highest. Listen closely for a click, if you hear a click, the thermostat is not bad. However, if you do not hear a click, then the thermostat is defective and needs to be changed.

3. Damper

Check your manual to find out where your fridge’s damper is located, open up the compartment. Look to see if the damper is jammed open.

4. Temperature control board/Main control board

These are often not easily diagnosed and are rarely the problem. We, therefore, advise you to check the above-mentioned components first. If none of the other parts are faulty, then you may consider replacing the control or main board.

At the end of your inspection, the faulty component will have to be replaced. We advise that you call a repair technician for this.

How to Stop a Bosch Fridge from Freezing Food

If your Bosch fridge is freezing food, you first have to identify the problem. To do this, you have to try out the solutions to the first two problems we mentioned.

The first step to stop your fridge from freezing your food is to check and adjust the temperature. The best temperature for a fridge is 38 to 42°F. So if your fridge is below this, adjust it to this level. Be careful not to increase the temperature beyond that as it may cause your food to become too warm and begin to breed bacteria.

If your Bosch fridge keeps freezing food after you set the temperature to the ideal degree, you have to stock up your fridge.

You may wonder how the quantity of food in the fridge determines if your food gets frozen or not. It’s easy, if your fridge is properly stocked, the cold air that is vented into the fridge will be evenly absorbed. But, with a near-empty fridge, the cold air goes to the cavity’s bottom and ultimately freezes your food.

Also, check the door seal to ensure it creates a tight seal around the fridge door. If the seal is weak, it will cause the fridge to lose cold air while warm air replaces it. Since th warm air is usually laden with moisture, it is quick to condense in the cold interior and form frost. As the frost builds, it freezes food and may even prevent proper cooling, especially if it blocks the vents.

Therefore, test the seal with a dollar bill; close the door on the dollar bill and try pulling it out. If you can pull it out, the door seal is weak and yu should replace it.

If the problem is not solved after trying these solutions, then you may have a faulty component. Follow the steps above to troubleshoot and repair or replace the parts.
