A clever trick to try is placing a coin in a glass of ice water and leaving it in the fridge. Specifically, if after a break, the coin remains at the surface of the ice, it indicates that the fridge has been functioning normally and has not suffered a power outage, meaning your food is safe to consume.
If the coin is suspended in the middle of the glass, it suggests that your fridge experienced a brief power outage and stopped working for a short period. The ice didn’t fully melt, and the fridge resumed functioning, hence the coin’s position. In this case, the food may still be safe, but it’s advisable to inspect it thoroughly before consumption.
Should the coin settle at the bottom of the glass, it indicates a prolonged power outage, and your food is likely spoiled. It’s best to discard such food to prevent any health risks.
A helpful tip for this method is to use a transparent glass or plastic container to make ice. Avoid using ceramic or opaque containers, as they hinder the observation of the coin.
Instead of a coin, you can also use a small piece of metal for this test.
Additional Pre-Holiday Fridge Tips:
– Clean your fridge thoroughly:
Before the holiday break, ensure you clean your fridge, removing any spoiled or expired food to prevent rot, mold, and unpleasant odors.
– Avoid unplugging the fridge:
While it may be tempting to unplug the fridge during an extended holiday like the Lunar New Year to save energy and prevent fire hazards, doing so may not yield significant savings and could impair the fridge’s functionality or even damage it.
When the fridge is unplugged for an extended period, the evaporator and condenser may oxidize due to a lack of drying, resulting in reduced cooling efficiency, leaks, and a shorter lifespan.
To save energy, instead of unplugging the fridge, adjust the temperature to its lowest setting. For an empty fridge, once the desired temperature is reached, it will automatically turn off.
If you’re away for more than 15 days, consider unplugging the fridge to prevent issues like sudden power outages, gas leaks, or electrical faults. After unplugging, remove all food items to prevent spoilage and bacterial growth. Also, ensure the fridge is thoroughly cleaned and dried to prevent musty odors and potential damage.
