Bosch Refrigerator Alarm Going Off – How to Fix

You may hear your Bosch refrigerator alarm going off from time to time. This is normal, especially when there is a power failure or you accidentally leave the door open. If you hear the refrigerator alarm going off all the time, it is crucial to check the door.

The likeliest reason is that the door gasket has worn out. But before checking the gasket, ensure nothing sticks out of the refrigerator to keep the door from closing tightly. You may have to rearrange the contents to make it easier for the door to close. 

Do the same for the shelves and racks. Additionally, check the door bins to ensure you have not overstocked them. The door may have difficulty closing if the door is weighed down. In other words, it may affect the hinges and may even cause them to become slack and break over time.

If nothing is sticking out, you may want to check the door gasket. Over time, it gets dirty with food crumbs and spills. And as the dirt builds, it becomes increasingly difficult for the door to seal tightly. Apart from dirt, age or poor usage can cause the gasket to become too weak. So, if it is not dirt, it may be that the gasket is simply worn out.

If you suspect a faulty gasket on your refrigerator is causing the alarm to go off all the time, try cleaning it. Use warm soapy water to remove the dirt and grime on it as thoroughly as possible. If a soft cloth is not strong enough to clean it, use an old soft-bristled toothbrush. It should reach the crevices and folds of the rubber seal to remove stubborn stains.

When the Temperature Is too High

Sometimes, the slightly open door may cause the temperature to rise, which makes the beeping worse. The reason is that the door and temperature are not in good order, triggering the appliance to alert you.

First, check the temperature setting to ensure it is correct. Sometimes, an accidental change can increase the internal temperature and trigger the alarm. If that is the case, simply adjust the setting and give the refrigerator 24 hours to adapt to the new setting. But if the setting is correct, ensure the door closes and seals tightly.

Also, check the door hinge to see if it is broken or slack. That will affect the door frame and let warm air into the refrigerator, compromising the internal temperature. You will need new hinges if the old ones are damaged or weak.

1. Check for Power Interruptions

Sometimes, power interruptions cause the refrigerator’s temperature alarm to go off. You may be unaware of the power failure, but the alarm alerts you to it, especially when the interruption lasts too long. As the internal temperature begins to rise, the temperature alarm beeps to inform you so that you can fix it.

2. Check the Thermistor

Another possible cause is that the temperature sensor is faulty. The sensor, also known as the thermistor, detects the temperature to know when the cooling system needs to run to produce cool air. Therefore, the temperature alarm does not go off unless the sensor informs it of the temperature issue.

However, if the sensor becomes defective, it may incorrectly detect the temperature as warm when it is not. Consequently, it will inform the alarm, which goes off and beeps continuously. If the temperature is correct, the door is tightly sealed, and there is no recent power failure, it is crucial to test the sensor.

Locate the thermistor in your Bosch refrigerator model using the user guide. Remove it from the appliance and use a multimeter to test its resistance. If the sensor shows no continuity when tested, it is best to replace it.

3. Check the Main Control Board

If all else fails, the control board may be malfunctioning. Since the board governs the entire refrigerator function, it can determine how the alarm works. The audible feature is typically on the control board, so it may sound when the board malfunctions.

If that is the case, there is usually no way to repair the board is to replace it. But before doing that, it is best to have a trained technician check it. Control boards are easy to misdiagnose; because of this, users easily throw good control boards out. However, replace the main control board if it appears to be damaged. Contact the Bosch Service Center for further assistance.

Note: These steps also apply if the alarm problem is with your Bosch freezer. Ensure you shut the door and allow the temperature to drop until it is food-safe. The alarm usually stops beeping and flashing by itself. They also apply to all Bosch refrigerator and freezer models.

How to Disable the Open Door Alarm on a Bosch Refrigerator

There is no way to disable the open-door alarm on any Bosch refrigerator. The brand does not design its refrigerators in such a way that you can disable the door or temperature alarm because the alarm is a safety measure.

You can temporarily turn the alarm off by pressing the alarm button on the control panel. Depending on the model, the alarm button may stand alone or may be marked Alarm/Lock. Follow the instructions on the refrigerator’s dedicated user manual or online manual to determine how to turn the alarm off. But typically, you press the button and hold it for about three seconds.

If you want to stop the alarm from beeping, it may mean cutting the speaker off from the main control board. But while this may solve the beeping problem, it may damage other things. So, you have the option of temporarily shutting the alarm off or permanently cutting off the speaker from the control board.

If unsure of where to find it, use the manual for the refrigerator to find the button. Follow the instructions in the manual to press and hold the button to activate the alarm.

You or someone else may accidentally turn off the alarm, which may trigger the Alarm Off to display. This is usually nothing to worry about unless it keeps displaying an alarm-off signal. If resetting the alarm does not solve the problem, reset the entire refrigerator and see what happens.

Disconnect it from the electric power for about five to ten minutes to reset it. During that time, keep the refrigerator door closed and untouched. Afterward, turn it on again and check the display. Such a reset should correct minor errors and faults; otherwise, have a professional check your appliance and make necessary repairs.
