How to Change LG Air Conditioner from Celsius to Fahrenheit

If you’ve recently purchased an LG air conditioner or moved to a new home with one already installed, you might notice the temperature display is set to Celsius (°C) instead of Fahrenheit (°F). While Celsius is the standard in many parts of the world, Fahrenheit is more familiar to users in the United States and a few other countries. Fortunately, switching your LG air conditioner from Celsius to Fahrenheit is a quick and easy process—no tools or technical skills required.

In this comprehensive guide, you’ll learn exactly how to change the temperature unit on your LG air conditioner, whether it’s a window unit, portable AC, or split system. We’ll walk you through the most common methods using the remote control, explain what to do if your remote isn’t working, and provide troubleshooting tips for stubborn units. By the end, you’ll have your AC displaying temperatures in Fahrenheit and feel confident managing other settings too.

Let’s get started!

Why Change from Celsius to Fahrenheit?

Before diving into the steps, it’s helpful to understand why you might want to make this change. Temperature scales can be confusing, especially if you’re used to one system and suddenly see the other. Here’s a quick breakdown:

– Fahrenheit (°F): Commonly used in the United States. Water freezes at 32°F and boils at 212°F. Room temperature is typically around 68–72°F.
– Celsius (°C): Used in most other countries. Water freezes at 0°C and boils at 100°C. Room temperature is about 20–22°C.

If you’re in the U.S. or another country that uses Fahrenheit, seeing “25°C” on your AC display might not mean much at first glance. Converting that to 77°F makes it instantly understandable. Switching to Fahrenheit ensures you can set your desired comfort level without mental math or confusion.

Additionally, many people find Fahrenheit offers finer gradations for comfort. For example, a 1-degree change in Fahrenheit feels more precise than a 1-degree change in Celsius, which is almost twice as large in terms of actual temperature shift.

Method 1: Using the Remote Control (Most Common)

The easiest and most reliable way to change your LG air conditioner from Celsius to Fahrenheit is by using the remote control. Most LG models—especially newer ones—allow you to toggle between temperature units with a simple button press. Here’s how:

Step 1: Turn On Your Air Conditioner

Make sure your LG air conditioner is powered on. You can do this by pressing the “Power” button on the remote or the unit itself. The display should light up, showing the current temperature and mode (Cool, Heat, Fan, etc.).

Step 2: Locate the “Temp” or “Mode” Button

Look at your remote control. You’ll typically find a button labeled “Temp,” “Temperature,” or sometimes just “Mode.” On some models, this button may also have a small icon like a thermometer or degree symbol (°).

Step 3: Press and Hold the Button

Press and hold the “Temp” or “Mode” button for about 3 to 5 seconds. You should see the temperature unit on the display change from °C to °F (or vice versa). For example, if it was showing “24°C,” it might now show “75°F.”

Tip: On some LG remotes, you may need to press the button repeatedly instead of holding it. Try both methods if the first doesn’t work.

Step 4: Confirm the Change

Once the display switches to Fahrenheit, release the button. The change should be saved automatically. Test it by adjusting the temperature up or down—your new setting should now be in °F.

Example: If you set the AC to 70°F, the display will show “70°F” instead of “21°C.”

Step 5: Test Other Functions

To ensure everything is working correctly, try changing the mode (Cool, Heat, Fan) or adjusting the fan speed. The temperature should remain in Fahrenheit across all settings.

Method 2: Using the Control Panel on the Unit

If your remote control is missing, broken, or not responding, you can still change the temperature unit directly from the air conditioner’s control panel. This method works for window units, portable ACs, and some split systems with physical buttons.

Step 1: Locate the Control Panel

Find the control panel on your LG air conditioner. It’s usually on the front or top of the unit and may have buttons for Power, Mode, Temperature, and Fan Speed.

Step 2: Turn On the Unit

Press the “Power” button to turn on the air conditioner. Wait for the display to activate.

Step 3: Find the Temperature or Mode Button

Look for a button labeled “Temp,” “Temperature,” or “Mode.” On some models, this might be combined with another function, so check your user manual if you’re unsure.

Step 4: Press and Hold the Button

Press and hold the temperature or mode button for 3 to 5 seconds. Watch the display—it should switch from °C to °F.

Note: On certain LG portable or window units, you may need to press a combination of buttons (e.g., “Mode” + “Fan”) to access the temperature unit setting. Refer to your manual for exact steps.

Step 5: Save and Test

Once the display changes to Fahrenheit, release the button. The setting should be saved. Test by adjusting the temperature to confirm it’s now in °F.

Method 3: Using the LG ThinQ App (Smart Models)

If you have a smart LG air conditioner that connects to Wi-Fi, you can control it using the LG ThinQ app on your smartphone. This method is especially useful if you’ve lost your remote or prefer managing settings from your phone.

Step 1: Download and Open the LG ThinQ App

If you haven’t already, download the LG ThinQ app from the App Store (iOS) or Google Play (Android). Open the app and log in to your account.

Step 2: Add Your Air Conditioner

If your AC isn’t already connected, follow the in-app instructions to add it. You’ll typically need to press and hold the “Wi-Fi” or “Connect” button on the unit until it enters pairing mode.

Step 3: Navigate to Settings

Once your AC is connected, tap on it in the app. Look for a “Settings” or “Preferences” option—this is usually represented by a gear icon.

Step 4: Change Temperature Unit

In the settings menu, find the “Temperature Unit” or “Display Unit” option. Tap it and select “Fahrenheit (°F)” from the dropdown or toggle switch.

Step 5: Save and Sync

Tap “Save” or “Apply.” The app will send the command to your air conditioner. Wait a few seconds, then check the display on the unit or in the app to confirm the change.

Tip: The LG ThinQ app also lets you set schedules, monitor energy usage, and receive maintenance alerts—making it a powerful tool for managing your AC.

Troubleshooting Common Issues

Sometimes, changing the temperature unit doesn’t work as expected. Here are some common problems and how to fix them:

Issue 1: The Display Doesn’t Change

If pressing the button doesn’t switch from °C to °F, try the following:

– Check the remote batteries: Weak or dead batteries can prevent commands from being sent. Replace them with fresh ones.
– Ensure you’re pressing the right button: Some remotes have multiple buttons with similar labels. Double-check your user manual.
– Try a power reset: Turn off the AC, unplug it from the wall, wait 30 seconds, then plug it back in and try again.

Issue 2: The Change Reverts After a Few Minutes

If the display switches back to Celsius after a short time, it could be due to a software glitch or power interruption.

– Repeat the process: Try changing the unit again using the same method.
