Error codeH or HI
ApplianceRefrigerator
When H or HI blinks
The temperature reading flashes HI and a tone sounds. Frigidaire uses this alert when the refrigerator or the freezer has been warmer than it should be for more than one hour. A door left standing open for a long time is the usual trigger.
Steps in order
Push each door fully shut and make sure the seal sits flat.
On many models a reset follows: pull the plug for 30 seconds, then plug it in again.
If the plug is out of reach, switch the breaker at the fuse box off and on instead. That also resets everything else wired to the same circuit.
Look up your model in the use and care guide for its own details.
The separate door ajar tone
A door that stays open longer than 5 minutes makes the door ajar tone sound. Shutting the door stops it.

PF: a power outage, which may set off the high temperature alarm too
When the alert returns even though the doors close properly, Frigidaire refrigerator repair is available around San Francisco and the Bay Area at (415) 319-6371. Have ready which compartment feels warm, the model number and the reset you used.
Model compatibility: Frigidaire reuses codes across series and model years, so H or HI may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
H or HI means the refrigerator or freezer stayed too warm for more than one hour.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
