No, it is not safe to put hot water in an empty refrigerator. Putting hot or warm water into an empty fridge can lead to several issues and potentially damage the appliance:
Food Safety Concerns: Placing hot water in a fridge can raise the internal temperature of the refrigerator. This increase in temperature can promote the growth of bacteria and other microorganisms, which can lead to food spoilage and pose a risk to food safety.
Appliance Damage: Rapidly changing the temperature inside the refrigerator can cause stress on its components, especially the cooling system. Sudden temperature fluctuations may lead to compressor damage or other cooling system issues, potentially resulting in costly repairs.
If you need to cool down food or beverages quickly, it's better to let them cool at room temperature for a while before transferring them to the refrigerator. This approach helps avoid extreme temperature changes inside the fridge.
Additionally, it's essential to keep your refrigerator at the proper temperature setting (usually between 34°F to 40°F or 1°C to 4°C) to ensure food stays fresh and safe to eat. Always check the manufacturer's guidelines for your specific refrigerator model and follow their recommended practices to maintain its efficiency and prolong its lifespan.
