How to Read a Refrigerator Thermometer?

August 29, 2020 By Miranda Jackson Leave a Comment

Refrigerator thermometers are digital temperature monitoring devices powered by a lithium battery. Although most modern refrigerators are equipped with a built-in thermometer, these are usually analog or dial meters and do not always display the correct internal temperature and correction, refrigerator, freezer, or vegetable compartments. Homeowners and restaurateurs use refrigerator thermometers to monitor the performance of their lockers to adjust the temperature to save energy and preserve food.

How to read a refrigerator thermometer

Instructions

  1. Turn the refrigerator thermometer to the “On” position. Set the refrigerator thermometer to read Fahrenheit or Celsius by manipulating the switch on the refrigerator thermometer.
  2. Place two refrigerator thermometers in the refrigerator next to each other. Allow 30 to 60 minutes to pass, and then take the two-meter reading noting the temperature display.
  3. Compare the displayed temperatures with each other, at the same time as reading the temperature on the built-in analog or digital thermometer to establish a baseline.
  4. Read the refrigerator thermometers in increments of one-hour intervals for a period of four to five hours to see if the internal temperature is consistent. Adjust the refrigerator temperature controller so that the weather is below 40 degrees Fahrenheit.

How to check Refrigerator temperatures

Check the refrigerator temperature when you have had too many glasses of like hot milk or a bottle of beer. If you are tired of food that is not quite cold to your liking, it may be time to check to make sure your fridge is cooling correctly. For best results, observe refrigerator temperatures over a few days.

Things you need

  • Refrigerator thermometer
  • Glass
  • Water

Instructions

  1. Get a fridge/freezer thermometer device to use to test temperatures.
  2. Place the thermometer in a glass of water. Put the water glass on the middle shelf of the refrigerator. Leave the glass of water alone for 5 to 8 hours.
  3. Check the temperature. If it is not between 38 and 40 degrees F, set the refrigerator temperature to be cold or warm.
  4. Let the glass rest for another 5 to 8 hours and recheck the glass.
  5. Remove the thermometer from the glass of water as soon as the correct temperature is reached. Leave the thermometer in the refrigerator.
  6. Check the thermometer now and then to make sure it is at least 40 degrees F or below.
  7. Move the thermometer to different places in the refrigerator, from time to time, to check that the air temperature in all parts of the unit is below 40 degrees F.

Tips and Warnings

If your refrigerator runs continuously cold, the factory setting may not work correctly. Try turning the chiller adjuster up. If the refrigerator does not trip, it may be defective.

If your temperatures do not stay consistent, your refrigerator may be low on refrigerant or getting too old to handle the temperature changes of the environment around it.
