Quick Assessment

Answer to continue safely

Is it safe to keep using?

Maybe. If the alarm was triggered by an open door, closing it should resolve the issue. If the compressor is not running, food safety may be compromised — check temperatures with a thermometer.

Can I reset the code?

Yes. Press the alarm reset button on the control panel. If the temperature returns to normal, the alarm will clear. Power cycling by unplugging for 5 minutes can also reset.

When to stop immediately?

Stop if you notice: If refrigerator temperature stays above 40°F for more than 2 hours, If the compressor does not restart after power cycling.

Symptoms You May Notice

HI displayed on control panel

The temperature display shows HI or flashes a high-temp warning.

Food feels warm

Items in the refrigerator or freezer feel warmer than expected.

Audible alarm sounding

A beeping or continuous alarm alerts you to the temperature rise.

Possible Causes

1

Door left open

The refrigerator or freezer door was left ajar, allowing warm air to enter.

DIY Possible
2

Condenser coils dirty

Dust buildup on the condenser coils reduces heat dissipation, raising internal temperatures.

DIY Possible
3

Compressor or sealed system failure

The compressor is not running or a refrigerant leak has occurred.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Check doors are fully closed

    Ensure both the refrigerator and freezer doors are completely closed and the seals are making full contact.

    Run your hand along the door gasket to feel for air leaks.

  2. 2

    Clean condenser coils

    Unplug the refrigerator, locate the condenser coils (usually at the bottom or back), and vacuum dust and debris.

    Clean condenser coils every 6 months to prevent cooling issues.

    Tools required
  3. 3

    Check compressor operation

    Listen near the bottom rear of the unit for the compressor running. If silent, power cycle by unplugging for 5 minutes.

    A clicking sound followed by silence may indicate a failing start relay.

When to Call a Professional

Contact a qualified technician if:

  • Compressor does not start after power cycle and relay replacement
  • Refrigerant leak suspected (oily residue near coils)
  • Temperature remains high despite clean coils and closed doors
