Why does the alarm on my Bosch freezer go off several times an hour when the temperature is at -20°C?

Question

Accepted Answer

If the alarm on your Bosch freezer goes off several times an hour while the displayed temperature is stable at -20°C, several causes may explain this malfunction:

1. Check the freezer door

Make sure the door is properly closed and that the seal is in good condition.
A poorly closed door or a worn seal can allow warm air to enter, triggering the alarm.

2. Air circulation and freezer load

Do not overload the freezer to allow for proper cold air circulation.
Avoid placing hot food inside that may temporarily raise the internal temperature.

3. Check the internal fan

The fan ensures the circulation of cold air in the freezer.
A blocked or faulty fan can lead to poor cold distribution and trigger the alarm.

4. Presence of frost or ice

An excessive buildup of frost can disrupt the operation of the freezer.
Defrost if necessary to optimize performance.

5. Temperature settings and sensors

Check that the temperature is set according to the manufacturer's recommendations.
A faulty or poorly calibrated temperature sensor can cause false alerts.

If after these checks the alarm continues to go off for no apparent reason, it is possible that a technical issue requires the intervention of a qualified professional.

In summary, the alarm may go off despite a correctly displayed temperature due to a poorly closed door, poor air circulation, a faulty fan, frost buildup, or a sensor issue. Check these points to resolve the problem.
