Frigidaire Refrigerator H1 error code

High temperature alarm. The refrigerator or freezer has stayed too warm for over an hour, and the control is warning you.

Also shown as: H1, HI, H

Last updated: October 6, 2026

Quick answer: Frigidaire refrigerator error code H1: high temperature alarm. The most common cause is door left open or not sealing. Try this first — close the doors and wait. If that does not clear it, clean the condenser coils. If the code persists, call a qualified technician.

What causes the H1 error?

  • Door left open or not sealing
  • Large amount of warm food loaded at once
  • Dirty condenser coils reducing cooling
  • Extended power outage
  • Failing cooling system (compressor or refrigerant issue)

How to fix Frigidaire H1 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Close the doors and wait
    Make sure both doors are fully closed and nothing is blocking them. Check that the gaskets seal all around. Then leave the doors shut for several hours so temperatures can recover.
  2. Clean the condenser coils
    Unplug the refrigerator, pull it out, and vacuum the condenser coils (underneath or behind, depending on model). Dirty coils are a leading cause of weak cooling. Plug it back in afterward.
    Safety warning: Always unplug the refrigerator before cleaning coils or touching the rear components.
  3. Test the door seals
    Close the door on a dollar bill at several points around the gasket. If the bill slides out easily, the seal is weak and warm air is leaking in. Clean the gaskets and replace them if they are torn or flattened.
  4. Call a technician if temperatures will not recover
    If H1 persists for many hours with closed doors and clean coils, the sealed cooling system may be failing. That is not DIY territory.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • H1 stays on for many hours with doors closed and coils clean
  • The compressor never runs or runs constantly without cooling
  • You hear hissing or see oily residue (possible refrigerant leak)
  • The sealed cooling system needs professional service

Frequently asked questions

Is H1 an error code or just an alarm?

H1 is a warning, not a part failure. It means temperatures stayed too high for over an hour. Find and fix the cause, and the alarm clears as temperatures recover.

Is my food safe with H1 showing?

Move perishables to a cooler with ice. Food in the fresh-food section above 40 degrees for more than 2 hours should be discarded.

How do I silence the H1 alarm?

Press the alarm reset or mute button if your model has one, then fix the cause. The alarm returns if temperatures stay high.
