Here's how to find the right setting for *your* dorm refrigerator:
* Check the manual: Your refrigerator's manual should specify the temperature range and how the thermostat controls it. This is the best place to start.
* Use a refrigerator thermometer: The most accurate way to determine the temperature is to place a refrigerator thermometer inside. Adjust the thermostat until the thermometer reads within the 35-38°F range. These thermometers are inexpensive and readily available at most grocery stores or online.
* Start in the middle: If you don't have a manual or thermometer, begin by setting the thermostat to the middle setting. Monitor the temperature with your hand – it should feel noticeably cool, but not freezing. Adjust from there.
* Observe your food: If your food is spoiling faster than usual, your refrigerator is too warm. If ice crystals are forming on your food, it's too cold.
Important Considerations:
* Type of refrigerator: Mini-fridges and dorm refrigerators often have less precise temperature controls than larger models. Don't expect pinpoint accuracy.
* Location: The ambient temperature of your dorm room can affect the refrigerator's performance. A hotter room will require a colder setting.
* Frequency of opening: Frequent opening and closing will cause temperature fluctuations. Try to minimize this.
* Load: A full refrigerator will maintain a colder temperature than an empty one.
In short, finding the correct setting is an iterative process. Use a thermometer for accuracy, and adjust the thermostat based on your observations.
