Before diving into the “how,” let’s briefly cover the “why.” Temperature scales aren’t just about numbers—they’re about comfort, familiarity, and practicality.
In the United States, Fahrenheit is the standard unit for measuring temperature. Most Americans grow up understanding that 72°F feels comfortable, 90°F is hot, and 32°F is freezing. If you’re used to these benchmarks, seeing “22°C” on your AC display might feel confusing or imprecise.
Fahrenheit offers finer gradations between temperatures. For example, the difference between 70°F and 75°F is more noticeable than between 21°C and 24°C. This can help you fine-tune your comfort level, especially during mild weather when small adjustments make a big difference.
Additionally, if you’re sharing your home with family members or guests who prefer Fahrenheit, switching the display ensures everyone can easily understand and control the temperature.
Finally, some smart home systems or voice assistants (like Alexa or Google Home) may default to Fahrenheit when integrated with your AC. Matching your unit’s display to your preferred scale keeps everything consistent.
What You’ll Need
The beauty of changing your LG air conditioner’s temperature units is that it requires almost nothing. Here’s what you’ll need:
- The original remote control: Most LG ACs use infrared remotes with dedicated buttons for mode, temperature, and settings.
- A working air conditioner: The unit should be plugged in and powered on (even if it’s not actively cooling or heating).
- A few seconds of your time: The entire process takes less than a minute once you know the steps.
You do not need:
- Special tools
- Technical knowledge
- Access to the indoor or outdoor unit
- An internet connection (unless using a smart model with app control)
If your remote is missing or broken, don’t panic. We’ll cover alternatives later in the troubleshooting section.
Step-by-Step: How to Change LG Air Conditioner from C to F
Now for the main event. Below are detailed instructions for the most common LG air conditioner models. While exact button combinations can vary slightly, the core method remains consistent across window units, split systems, and portable ACs.
Method 1: Using the Remote Control (Most Common)
This is the standard method for the majority of LG air conditioners. It works on models like the LG LW8016ER, LG Dual Inverter Window AC, and LG Art Cool Mirror series.
Step 1: Turn on the Air Conditioner
Make sure your AC is plugged in and powered on. You don’t need to be in cooling or heating mode—just ensure the unit is receiving power and the remote can communicate with it.
Step 2: Locate the Remote Control
Find your LG remote. It should have buttons labeled “Power,” “Mode,” “Fan Speed,” “Temp Up,” “Temp Down,” and possibly “Filter” or “Energy Saver.”
Step 3: Press and Hold the Correct Button Combination
This is the key step. The most common method involves holding two buttons simultaneously for 3 to 5 seconds.
- For most LG window and split units: Press and hold the “Mode” button and the “Temp Up” (▲) button at the same time.
- For some portable or newer models: Try holding the “Filter” button and the “Temp Down” (▼) button.
Hold both buttons down for about 3–5 seconds. You’ll know it worked when the temperature display on the remote or indoor unit changes from °C to °F (or vice versa).
Step 4: Confirm the Change
Look at the temperature display. If it now shows “72°F” instead of “22°C,” you’ve successfully switched to Fahrenheit. If not, try the alternate button combination or proceed to troubleshooting.
Method 2: Using the Control Panel (For Units Without Remotes)
Some older or budget LG models may not come with a remote, or the remote may be lost. In these cases, you can often change the temperature units directly on the unit’s control panel.
Step 1: Locate the Control Panel
This is usually on the front of the indoor unit. Look for a small LCD screen and buttons labeled “Mode,” “Temp,” “Fan,” and “Power.”
Step 2: Enter Settings Mode
Press and hold the “Mode” button for 3–5 seconds until the display starts blinking or shows a settings menu.
Step 3: Navigate to Temperature Units
Use the “Temp Up” or “Temp Down” buttons to scroll through options until you see “°C” or “°F.”
Step 4: Select Fahrenheit
Press the “Mode” or “Set” button to confirm your selection. The display should update to show °F.
Step 5: Exit Settings
Wait a few seconds or press “Power” to exit the menu. The unit will return to normal operation with the new temperature scale.
Method 3: Using the LG ThinQ App (Smart Models Only)
If you have a Wi-Fi-enabled LG air conditioner (like the LG Dual Inverter Smart Window AC), you can change the temperature units using the LG ThinQ app.
Step 1: Open the LG ThinQ App
Make sure your phone is connected to the same Wi-Fi network as your AC.
Step 2: Select Your Air Conditioner
Tap on your AC unit from the home screen.
Step 3: Go to Settings
Look for a gear icon or “Settings” option within the AC control panel.
Step 4: Find Temperature Units
Scroll through the settings until you find “Temperature Unit” or “Display Unit.”
Step 5: Switch to Fahrenheit
Toggle the setting from °C to °F. The change should sync instantly with your unit.
Step 6: Confirm on the Unit
Check the display on your AC or remote to ensure the change took effect.
Model-Specific Examples
To make things even clearer, here are instructions for a few popular LG models:
LG LW1216ER (12,000 BTU Window Unit)
- Press and hold “Mode” and “Temp Up” for 3 seconds.
- The display will switch from °C to °F.
- Repeat to switch back.
LG Art Cool Premier (Mini-Split)

- Hold “Filter” and “Temp Down” for 5 seconds.
- Look for the °F symbol on the indoor unit display.
LG LP1419IVSM (Portable AC with Wi-Fi)
- Use the remote: Hold “Mode” and “Temp Up”.
- Or use the ThinQ app: Go to Settings > Temperature Unit > Fahrenheit.
Always refer to your user manual for the most accurate instructions. If you’ve lost your manual, you can download it for free from LG’s official support website by entering your model number.
Practical Tips for a Smooth Experience
Changing the temperature unit is simple, but a few tips can help you avoid frustration:
- Be patient with button holds: Some remotes require a full 5 seconds of holding. Don’t release too early.
- Try both hands: If one button combination doesn’t work, try the alternate (e.g., “Filter” + “Temp Down” instead of “Mode” + “Temp Up”).
- Check the remote batteries: Weak batteries can cause unresponsive buttons. Replace them if needed.
- Ensure line of sight: Point the remote directly at the AC’s sensor when pressing buttons.
- Don’t panic if it doesn’t work the first time: Some units require the AC to be in a specific mode (like “Cool” or “Fan”) before the setting can be changed.
Troubleshooting: What If It Doesn’t Work?
Even with clear instructions, things don’t always go smoothly. Here’s how to fix common issues:
The Display Won’t Change
- Solution: Try the alternate button combination. If “Mode” + “Temp Up” didn’t work, try “Filter” + “Temp Down.”
- Also try: Power cycling the unit. Turn off the AC, unplug it for 30 seconds, then plug it back in and try again.
The Remote Isn’t Working
- Solution: Replace the batteries. Use only high-quality alkaline batteries.
- Alternative: Use the control panel on the unit itself (if available).
- For smart models: Use the LG ThinQ app as a remote substitute.
The AC Doesn’t Have a Remote or Control Panel
- Solution: This is rare, but some very basic models may not support unit changes. In this case, you may need to estimate conversions (e.g., 22°C ≈ 72°F).
- Upgrade tip: Consider purchasing a universal remote compatible with LG ACs.
The Setting Reverts After a Power Outage
- Solution: Some units reset to factory defaults after a power loss. Simply repeat the process to switch back to Fahrenheit.
- Prevention: Use a surge protector or UPS to maintain stable power.
You Can’t Find Your Model Number
- Solution: Check the label on the side or back of the indoor unit. It usually includes the model and serial number.
- Alternative: Look for the manual that came with the unit, or search online using the unit’s physical features (e.g., “LG window AC with blue display”).
Why This Change Matters
You might be thinking, “It’s just a number—why bother?” But small changes like this can significantly improve your daily comfort.
Imagine coming home on a warm evening. You want the room to feel cool but not freezing. If your AC shows “24°C,” you might not know if that’s comfortable or too chilly. But if it shows “75°F,” you instantly recognize it as a pleasant, mild temperature.
Fahrenheit’s finer scale also helps with energy efficiency. Instead of jumping from 70°F to 75°F (a 5-degree leap), you can make smaller adjustments like 72°F or 73°F. This precision can help you find the sweet spot between comfort and energy savings.
Plus, if you’re using a smart thermostat or scheduling your AC, having consistent units across all devices reduces confusion and improves automation.
Final Thoughts
Changing your LG air conditioner from Celsius to Fahrenheit is a small change with a big impact on usability. Whether you’re adjusting for personal preference, household harmony, or smart home integration, the process is quick, free, and requires no special skills.
Remember: the key is knowing the right button combination for your model. Start with “Mode” + “Temp Up,” and if that doesn’t work, try “Filter” + “Temp Down.” For smart models, the LG ThinQ app offers a convenient alternative.
If you run into issues, don’t stress—most problems are easily fixed with a battery change, power cycle, or alternate method. And if all else fails, LG’s customer support team is available to help.
Now that you know how to change LG air conditioner from C to F, you can enjoy a more comfortable, intuitive cooling experience. So grab your remote, press those buttons, and enjoy the perfect temperature—your way.
