Frigidaire Refrigerator H / HI Error Code

Frigidaire says H, HI, or High Temp means a compartment exceeded its high-temperature threshold, commonly after a door issue or cooling interruption.

Applies to French-door and other Frigidaire refrigerators with high-temperature alerts

What the appliance detected

Detected condition

The refrigerator or freezer temperature is above the documented alert threshold.

What may contribute

Possible causes

  • A refrigerator or freezer door may have been open or not sealing.
  • Recent setting changes, loading, or a power event may affect temperature recovery.
  • A persistent alert can indicate the refrigerator needs service diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and model

    • Photograph or write down the exact alert, word, or code before clearing it.
    • Confirm the full model number and Frigidaire owner manual because displays and controls vary by refrigerator family.

  2. Use only documented external checks

    • Close doors fully and check for items blocking the gasket or door.
    • Confirm the model-recommended temperature settings and allow safe stabilization.
    • Use the model-documented clear-alert action if the alert is ready to clear.

  3. Stop before internal work

    • If the alert remains after documented checks, request service.
    • Do not open sealed-system, compressor, fan, sensor, wiring, dispenser-motor, or control areas.

Actions not recommended

  • Do not perform refrigerant, compressor, or sealed-system work.
  • Do not test live voltage or open internal electrical areas.
  • Do not replace sensors, boards, fans, valves, or dispenser parts based only on the display.

When to stop and request service

  • The alert continues after doors, settings, and power are addressed.
  • Compartment temperatures remain unsafe.
  • Cooling, gasket, sealed-system, or internal electrical diagnosis would be needed.
