How to Troubleshoot a Vicks Comfort Flex Thermometer

The Vicks Comfort Flex Digital thermometer provides fast, 30-second temperature readings with accuracy 1. It consists of an easy to read LCD display, which you can switch from Fahrenheit to Celsius readings, automatic shut-off to prolong the battery life and a storage case and probe covers to protect the thermometer. It’s waterproof so you can easily wash it, and gives a beep signal when it is finished reading your temperature. Using the Vicks Comfort Flex thermometer is simple, but there are a few things you should do to ensure the most accurate reading and to keep your thermometer running smoothly 1.

Turn the unit on and observe the display screen. If you don’t hear a beep or the screen does not flash red, yellow and then green, check the batteries. Typically, a small Vicks icon will flash when the batteries are dead.

Turn the unit over, and behind the display screen is the battery housing. Using a coin in the slot on the back, turn counter clockwise to open and remove old batteries. Replace with new batteries and snap the cover back on. Turn with the coin clockwise to tighten again. Your thermometer should now work.

Determine a normal temperature based on where you take your temperature. When the thermometer is used orally, a normal temperature reading is between 97 and 100 degrees Fahrenheit. A rectal temperature is typically one degree higher than it would be orally, and temperatures taken under the arm are one degree lower.

Record your temperature at two separate times in one day when you’re feeling well if you’re unsure of what your normal temperature should be. The average of the sum of those two temperatures is your normal temperature.

Avoid eating, drinking any liquids, showering, exercising, or smoking for at least 15 minutes before taking your temperature so that the Vicks Comfort Flex thermometer can provide you with the most accurate reading 1.

Retake your temperature if you are getting a display that reads “L” or “Lo.” This means the Vicks Comfort Flex is either in ready mode, which indicates it hasn’t read a temperature yet, or is reading a temperature lower than 90 degrees Fahrenheit.

Check that you’re placing the thermometer correctly in position. Under the arm temperatures should be taken with the thermometer probe end touching the skin under your arm and the unit positioned straight up and down. Lower your arm to the side of your body. If you’re reading your temperature under your tongue, make sure the probe is well under and your tongue is lowered and your mouth closed.

Wait for the unit to beep before removing. If it doesn’t beep, it hasn’t finished reading your temperature yet.

Return the Vicks Comfort Flex thermometer if you’ve tried all of these steps and it still is not working properly 1. The unit has a lifetime warranty as long as the unit has been properly used and the problem isn’t related to misuse or battery failure. Vicks will repair or replace your unit with a new one.
