What to check first
Can I keep using it?
Food safety first
Do not rely on the refrigerator for perishable food while this warning is active or temperatures are outside a safe range.
- Safe next step
- Check actual compartment temperature, move perishable food to safe cold storage if needed, and use the model manual for any further steps.
- Stop when
- Food is thawing, temperatures are unsafe, the unit is not cooling, or electrical symptoms appear.
Stop for leak or water warnings
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
