The refrigerator is one of the main "consumers" of electricity in every home. A simple trick with a banknote will help optimize the costs that result from using a refrigerator.
It turns out that you can use a banknote to determine how much electricity a refrigerator “eats.”
How the banknote lifehack works
If the refrigerator door is not closed tightly, the appliance will consume more electricity to maintain the required temperature inside.
This may happen due to a worn rubber seal around the perimeter of the door.
It is precisely to check the wear of the rubber that you will need a banknote.
Place it between the door and the shelf, close the refrigerator and try to get the bill out. If the bill comes out easily and without effort, this indicates that the rubber is worn out.
How to reduce energy consumption
To return the seal to its original condition, wash it with warm water and soap, then place it under a stream of warm air from a hair dryer.
This will make the elastic more flexible and will better follow the contours of the refrigerator.
