LG Refrigerator – Temperature Too Cold. What’s The Cause? How To Fix It?

A fridge is supposed to be cold. Otherwise, it’s not doing its job. However, there can always be too much of a good thing, like when an LG refrigerator drops its temperature too low. You’ve come to the right place if you’re facing that issue with your appliance.

An LG refrigerator temperature is too cold, most likely because it’s set too low in the first place. Ideally, your fridge should be set to around 37 degrees Fahrenheit. Besides that, a faulty temperature control thermostat or thermistor can cause the refrigerator to cool excessively. Lastly, check that your ice maker compartment is closed, as its freezing air could be the root cause.

This guide will walk you through the most likely reasons your LG fridge temperature is too cold. More importantly, you’ll also discover why it’s happening and what you can do about it.

Why Is My LG Refrigerator Getting Too Cold?

When your fridge is getting too cold and freezing your food, that means you’re dealing with one of the following:

Temperature Set Too Low

About this: Your refrigerator gives you plenty of freedom when choosing its compartment temperature. On top of that, you can also adjust different temperatures for the refrigerator and freezer compartments.

Ideally, your fridge should be set at 37 degrees Fahrenheit. However, you can set it anywhere between 33 and 46 degrees depending on your local climate, the room temperature around your fridge, and the kinds of items you plan on storing inside.

What’s happening: When troubleshooting a fridge that’s getting too cold, you must always start with the most straightforward problems and solutions. In this case, your fridge is probably cooling down too much because you’ve set its temperature too low.

When that happens, the fridge will provide more cooling than you require. As a result, your food items will not only become cold, but some might even freeze. 

That can also lead to other issues like frost and ice buildups inside the compartment, especially around the air vents and fans.

How to correct it: Again, 37 degrees is an ideal fridge temperature setting for most people. However, you can adjust that number up and down as needed to create an ideal environment for your food items.

When experimenting with different temperature settings, always adjust it one degree at a time. Then, give the fridge 24 hours to stabilize its compartment temperature according to the new settings.

Faulty Temperature Control Thermostat

About this: After you input your temperature settings, a component called the temperature control thermostat takes over. Its job is to send signals to the fridge’s main control board, telling it what the set temperature is.

Once the control board receives those signals, it can control the cooling system to cool the appliance down to your chosen temperature.

What’s happening: When a fridge gets too cold, there’s a likelihood that the temperature control thermostat is sending the wrong signals. So, while you might choose a moderately cold temperature like 37 degrees, the faulty thermostat could mistakenly signal the board that you’ve set it much lower instead.

As a result, the fridge and its cooling system will continue to work towards a temperature that’s too cold compared to what you’ve chosen on the control panel.

How to correct it: Temperature control thermostats are not fixable. So, you’ll have first to test to ensure that the thermostat has failed.

A simple multimeter test for electrical continuity can do that.

Once you’re sure it’s the source of your fridge problem, you must replace it with a new one.

Thermistor Or Room Temperature Sensor

About this: Aside from thermostats, your LG refrigerator also has a thermistor or a room temperature sensor. However, unlike thermostats, these components do not control your fridge’s cooling processes.

Instead, they monitor the temperature inside your fridge compartments to ensure they’re at the correct levels. For example, they’ll trigger alarms and indicators if the fridge becomes too warm.

More importantly, they’ll measure the temperature to ensure that your fridge is as cold as you set it.

What’s happening: When the thermistor or temperature sensor fails, the main control board (i.e. the brain of your fridge) will mistakenly think that the refrigerator is a lot warmer than it is.

Due to that, the main control board will control the cooling system to make the fridge compartment colder.

Ultimately, your LG refrigerator temperature becomes too cold to store your food items correctly.

How to correct it: This problem will continue until you replace the thermistor or room temperature sensor. That means disconnecting and removing the existing component so you can install the new one in its place.

Once you do that, your fridge will accurately understand its current temperature and can cool the compartment down to your set temperature (and not make it colder).

Ice Maker Compartment Is Open

About this: Many LG refrigerator models come with an ice maker in the refrigerator compartment. The ice maker must reach freezing temperatures to fill the ice bucket.

Despite sharing the same pace, the ice maker is separated from the rest of the compartment and doesn’t share the same air. So, the temperatures of these two parts are different.

The refrigerator compartment is cold enough to preserve food, but the ice maker is freezing to make ice.

What’s happening: Remember: the ice maker shares the same space as the refrigerator compartment but is kept separate with a door. That door ensures that both parts do not share the same air.

However, if the ice maker compartment door is left open, that becomes a problem. The freezing air will make the fridge compartment much colder than it should be.

That’s why your refrigerator temperature becomes too cold and causes issues like freezing your food and drinks.

How to correct it: Thankfully, this problem is straightforward to fix. First, you must always ensure that the ice maker compartment is closed. That way, the freezing air is separated from the chilled atmosphere of your fridge compartment.

If you can’t do that for whatever reason, you should turn off the ice maker. Doing so will prevent your fridge from becoming too cold while you get the ice maker repaired.

Frequently Asked Question (FAQs)

Got a few more questions on your mind? These answers are sure to help.

Is 40 Degrees A Safe Temperature For A Refrigerator?

Yes, but only barely. Your LG fridge must always be 40 degrees Fahrenheit or lower to store your food safely. Any temperatures higher than that will encourage the growth of bacteria and make your food unsafe to eat.

How Do I Organize Food In My LG French Door Refrigerator?

You should organize your food items so that there is enough space for air to travel around them. That way, you will maximize airflow and allow cold air to reach all corners of the refrigerator compartment.

How Long Do You Have To Wait To Put Food In A New LG Refrigerator?

When you install a new LG refrigerator in your home, you should wait at least 2-3 hours before putting food in. That time allows the fridge to cool itself down somewhat and make it safer for the items you’ll load into it.

How Do I Turn Off The Ice Maker In My LG Refrigerator?

Depending on your fridge model, you can turn the ice maker off by either pressing its button on the control panel or flipping the power switch on the ice maker unit. If you’re unsure, refer to your user manual to see what steps apply to your model.
