What does the High Temp alarm mean and what should I do?

The High Temp alarm activates when the internal temperature of the refrigerator rises and stays above the safe temperature zone for a period of time, displaying 'HI' on the corresponding compartment display with an alarm sounding every 10 seconds. The refrigerator will automatically try to cool down to improve the condition. If the temperature has not cooled after some time and the warning reappears, call 1-800-374-4432. (Page 18)
