Error codeH / HI
ApplianceRefrigerator
Quick answer
H or HI on a Frigidaire refrigerator means a compartment has been too warm for over an hour. Check door closure and seals.
Model compatibility: Frigidaire has used more than one control platform, so H / HI may mean something different on another appliance or generation. Confirm this against your model documentation and record your full model number before acting.
Plain language
What this code means
High temperature: refrigerator or freezer too warm for over an hour, with a blinking temperature and a tone.
Reading a blinking HI
Frigidaire refrigerators display H or HI when the temperature inside the refrigerator or freezer has stayed too high for over one hour. The temperature figure blinks and a tone is heard. Most often the cause is a door that was left open for a long time.
Quick list
Confirm each door is closed all the way and the seal sits properly.
To reset, depending on the model, unplug the refrigerator for 30 seconds and plug it in again.
When the plug is out of reach, the breaker at the fuse box can be flipped instead. Everything on that circuit resets with it.
Check the use and care guide for details on your model.
Leaving a door open for over 5 minutes sets off the door ajar tone, which stops when the door is closed.
Nearby codes
PF: power outage or surge, may bring on a high temp alarm
OP: open thermistor for the fresh-food or freezer side
SH: shorted thermistor for the fresh-food or freezer side
