Quick answer: A temperature alarm means the appliance detected a condition outside its expected range; the cause can be temporary or indicate a fault.
Temporary reasons for an alarm
A door held open, a large load of warm food, a recent power interruption or extended cleaning can temporarily raise temperature.
When the alarm needs service
If the alarm returns after the doors stay closed, the cabinet remains warm, or the compressor/fans behave abnormally, a sensor, airflow, control or refrigeration fault may be present.
Protect the contents
Keep the doors closed, record the displayed temperature and move temperature-sensitive items if the cabinet cannot maintain a safe range.
