How To Check Fridge Temperature Without Thermometer? 2 Best Methods!

Does your fridge have no thermistor and control board, so you want to know how to check fridge temperature without thermometer? Because some of these items are uncommon in our houses, we’ll have to devise some life hacks to perform specific tasks. And concerning your fridge’s temperature, we have two methods for you.

Before starting with the main topic, have you noticed that your food spoiled instantly and that the fridge isn’t cold enough? But you wouldn’t know what caused it since your fridge doesn’t have a display board. So, you checked if it’s plugged on or there’s a power outage. However, the light inside the fridge is on.

What could be the cause of temperature change? You wouldn’t even notice that the temperature rose since you have no temperature sensor. But don’t worry because we’ll have every problem addressed after this article. Stay tuned!


Methods To Check The Fridge Temperature Without Thermometer

In these methods, we’re going to utilize materials that are available in our household. So, it doesn’t matter if you have a standard fridge or an advanced one. Or you don’t have a thermometer as long as you pay attention to the temperature of your fridge.

Now, here are the methods we gathered on how to check fridge temperature without thermometer:


Method #1. Water as an alternative thermometer

Water could not give you accurate temperature readings. But why did we include this in our methods? Even though it’s not that accurate, you can observe how the water reacts after removing it from the fridge. If you love science, think of this as an experiment.


Step #1. Fill up your container

So, you can either use a cup or bowl. If you want to observe the results quickly, for example, 1-2 hours, you should choose a smaller container. Most methods record their fridge temperature using this, but they usually place a thermometer in the cup of water.

However, because not everyone has a thermometer, we can just put the water inside and check it later.

Use room temperature water so that we wouldn’t alter the results. You can also place one cup in the freezer and the other one in the fridge.


Step #2. Wait

You can leave it for 1-2 hours, except if you placed a larger container. That is because it will take time for the water to absorb the temperature inside the fridge. At this moment, you can examine your fridge if any slight differences might cause temperature issues.

For example, you can adjust its placement by moving it a couple of inches away from the wall. Ensure if the compressor executes proper ventilation and remove any debris that prevents airflow. Also, check if there are unusual sounds and smells.


Step #3. Take out your water

Gently take out the container and don’t spill the water. It might result in an unpleasant smell if not drained. Then, you can dip your fingers and check the current temperature. And observe the water for a couple of seconds if there are any changes. You know, simple science.

If the temperature inside the fridge stays the same, it’s at room temperature, which implies it’s neither chilly nor hot. Still, food spoils at this temperature. If condensation appears in the container, it means that the water and fridge are cold. This method could not give you accurate results, but it can show any temperature issues.


Method #2. Use your senses

We can use this method to check if the fridge is not working efficiently. If we suspect this situation, the first thing we need to check is the signs of overheating. For example, your fridge might not be cooling because of improper ventilation and airflow.

Like the previous method, this procedure could not give you accurate results, but it can work and make you take immediate action. However, this method requires your knowledge of the warmth on the sides of your fridge.

You should know how hot the sides are and that you’re familiar with them. So the first step is to compare the current warmth of the fridge’s sides to the temperature yesterday or the other day. Is it too hot today? Or has nothing changed?

These questions will address your goal, and you might be able to prevent further overheating. For example, hotter sides mean that something might strain the cooling activity of the fridge. Or the heat from the discharge lines has no way out.

Now that got over the methods on how you can check your fridge temperature. You might as well read about the reasons why your fridge is making noise when the door is closed. Regardless, always make sure that the thermostat in your refrigerator is at its ideal point, or your food will go bad quickly.


It’s A Wrap

And that is how to check fridge temperature without thermometer. With the results you gathered, you can now adjust your fridge’s temperature through the thermostat inside the unit. But take note that the mini-experiment we did is not accurate.

Even though the methods above could give you convenience and allow you to monitor your fridge despite the lack of equipment, we suggest you upgrade to a newer fridge model.

You will eventually need some additional features such as a display board to monitor it regularly. Plus, modern refrigerators consume less energy than older ones. We hope you gained knowledge from this post. All the best!
