For a refrigerator to run properly, it is essential that fridge thermostats be in working order. If the thermostat is not working properly, the refrigerator might not keep the food cold enough, even though you turn the controls as cold as you can get them.
On the other hand, a poorly working thermostat might cause the fridge to kick on too frequently, keeping the food too cold and wasting electricity. For top economy, home owners need to make sure their fridge thermostats are working correctly.
To check your fridge thermostats, it is helpful to get a refrigerator thermometer. Place one in each refrigerator and periodically check the internal temperature. It should stay between 2 and 6 degrees Celsius, or 36 to 43 degrees Fahrenheit. If you need to adjust the controls to reach this range, do so. If you can’t reach this range, you may need to install an external thermostat, or have it replaced by a repairman.
There are ways to make your refrigerator more efficient in using energy. One tip is to let hot foods cool to room temperature first, then place them in the fridge. If you don’t do this, fridge thermostats are bound to kick on and run the refrigerator more than otherwise necessary.
Another common sense tip is to place the fridge in a cooler area of the home. This means that you do not place it where the sun will be beating down on it, or where the heat from the wood stove will be causing it to work harder than it should.
If you feel like your fridge thermostats might be going out, first check to make sure the gaskets around the doors seal properly. If air is getting into one of your refrigerators, it will make the fridge work less efficiently, and the thermostat will kick on too much, resulting in a waste of electricity.
It is normal for fridge thermostats to cause a refrigerator to run for about half the time during the winter and three fourths of the time during the summer. Keeping the door closed should help keep that figure down. Every time you open the door, you let some cold air out and cause the fridge to have to work harder.
One creative frugal person fitted an old chest freezer with fridge thermostats in order to convert it into a refrigerator. This inventive person figured that the very design of an upright fridge was not very energy efficient. Cold air tends to sink, while hot air rises. A chest design is simply more energy efficient because the cold air will tend to stay inside the chest when the lid is lifted. Just think of the huge refrigerator and freezer units in supermarkets that don’t even have a lid at all.
There are other things you can do to make fridge thermostats work less and the fridge keep your food in better condition.
One thing you may not know is that just like an air conditioner removes humidity from the air, a refrigerator also removes humidity. This means that your food will dry out if it is not wrapped. Eggs do better when they are kept in the cartons. Otherwise they can dry out. Vegetables should be wrapped in plastic even if they are being kept in the crisper drawer. Wrapping food also keeps it from absorbing odors from other foods.
