Before going back to the countryside for Tet or any long holiday, it is best to make an ice cube tray with a coin placed on it and put it in the refrigerator. This can help you accurately measure whether there is a power outage during your absence, how long it lasted, and how much the food was affected.
In particular, if the coin is still on the surface of the ice tray after the holiday, it means that the refrigerator is still functioning normally, without any sudden power outage, and the food can be used normally.
If the coin is suspended in the middle of the tray, your refrigerator has experienced a brief power outage and stopped working for a short time. The ice has not had time to completely melt before the refrigerator restarted, so the coin is suspended in the middle. In this case, the food may not be spoiled, but it is still better to check thoroughly before use.
If the coin is at the bottom of the tray, it indicates that the refrigerator has experienced a long power outage and stopped working. In this case, the food may have spoiled, and you should avoid using it to prevent harm to your health.
Note that when doing this, you should use a transparent glass or plastic cup to make the ice. Do not use ceramic cups because it is difficult to observe the coin in that case.
In addition to using a coin, you can replace it with a small piece of metal.
Other notes when cleaning the refrigerator before going back to the countryside for Tet
– Clean the refrigerator:
Before the Tet holiday, you should clean and wipe the refrigerator, remove spoiled and expired food to prevent decay, mold growth, and unpleasant odor in the refrigerator.
– Do not unplug the refrigerator:
Many people worry that the refrigerator will consume too much electricity during long holidays like Tet, so they unplug the refrigerator. However, this does not save much cost and can reduce the functionality of the refrigerator or even cause damage.
The reason is that when the refrigerator is unplugged for a long time, the condenser and evaporator system may oxidize due to lack of drying, causing the refrigerator to lose cooling, coil damage, and reduced lifespan.
To save electricity for the refrigerator, instead of unplugging it, you can lower the temperature of the refrigerator to the lowest level. For refrigerators that do not store food, when it reaches the required temperature, the refrigerator will automatically shut off.
If you plan to be away for more than 15 days during Tet, it is advisable to unplug the refrigerator to prevent gas leaks, electrical system malfunctions, etc., in the event of a sudden power outage. After unplugging the refrigerator, remove all the food to prevent spoilage, odor, and the growth of harmful bacteria. Additionally, you should also clean and dry the refrigerator to prevent water and dirt accumulation, which can lead to odor or damage.
