Direct answer
On the covered Frigidaire refrigerator, H, HI means frigidaire states HI blinking indicates the temperature has been too high in the refrigerator or freezer for over an hour, and that it is usually activated when a door is left open too long. First, check food condition first — over an hour above temperature is a food-safety question.
Definition versus diagnosis

Preserve the failure state
ReversibleCheck food condition first — over an hour above temperature is a food-safety question. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleFrigidaire directs checking the doors are closed and properly sealed. Do not borrow a reset or meaning from a similar code, product or model year.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If H, HI returns, stop repeated resets and use model-specific manufacturer support.
