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.
