Status light
During the hours of daylight the green status light on the front of the cabinet should flash steadily
to indicate that the refrigerator is working correctly.
Important: The light does not give an indication that the correct vaccine storage temperature has
been reached. That is best found out by inspecting the fridge temperature display or measuring
the temperature directly.
The following table gives an indication of what the green light means and what actions should be
taken depending on its status.
