How to Turn Off Timer on Lg Air Conditioner

Turning off the timer on your LG air conditioner is simple once you know the right steps. Whether you’re using a remote control or accessing settings directly on the unit, this guide walks you through every method clearly and safely.

Key Takeaways

• Understand the timer function: The timer on LG air conditioners allows you to schedule when the unit turns on or off automatically, helping save energy and improve comfort.
• Use the remote control for most models: The majority of LG AC units can have their timers disabled using buttons on the remote, especially the “Timer” or “Cancel” options.

How to Turn Off Timer on LG Air Conditioner: A Complete 2026 Guide

If you’ve ever woken up to a freezing room because your LG air conditioner turned on at 3 a.m., or found yourself sweating because it shut off too early, you’re not alone. The timer function on LG air conditioners is a powerful feature designed to help you save energy and maintain comfort—but sometimes, it works a little too well. Whether you accidentally set a timer, forgot how to cancel it, or just want more control over when your AC runs, knowing how to turn off the timer is essential.

In this comprehensive guide, updated for 2026, we’ll walk you through every method to disable the timer on your LG air conditioner—whether you’re using a standard remote, a smart model with app integration, or a unit with only manual controls. You’ll learn step-by-step instructions, practical tips, troubleshooting advice, and even how to prevent future timer mishaps. By the end, you’ll have full control over your cooling schedule—no surprises, no confusion.

Let’s dive in.

What Is the Timer Function on an LG Air Conditioner?

Before we get into the “how,” it’s important to understand the “what.” The timer function on LG air conditioners allows you to program when the unit turns on or off automatically. This can be incredibly useful—for example, setting the AC to turn on 30 minutes before you get home so your house is cool when you arrive, or scheduling it to shut off after you fall asleep to save electricity.

There are typically two types of timers:

• On Timer: Schedules the air conditioner to turn on at a specific time.
• Off Timer: Schedules the unit to turn off after a set period or at a certain time.

Some advanced models even allow dual timers—both on and off—so you can create a full cooling schedule. However, if you don’t need this feature or accidentally activated it, it can be frustrating. That’s why knowing how to turn it off quickly is so valuable.

Why You Might Want to Turn Off the Timer

There are several common reasons users want to disable the timer:

• Accidental activation: It’s easy to press the wrong button on the remote and unintentionally set a timer.
• Changing routines: Your schedule may have shifted, making the old timer setting irrelevant.
• Energy concerns: If the AC turns on when no one’s home, it wastes power and increases bills.
• Comfort issues: The unit may shut off in the middle of the night, leaving you uncomfortable.
• Guest use: When visitors use the AC, they might not know how to manage the timer.

Whatever your reason, turning off the timer restores manual control and gives you peace of mind.

How to Turn Off Timer Using the Remote Control

The most common and convenient way to turn off the timer on an LG air conditioner is through the remote control. This method works for the majority of LG window, split, and portable units manufactured in the last decade—including 2026 models.

Step 1: Locate the Timer Button

Look at your LG remote. You’ll typically find a button labeled “Timer,” “Timer Off,” or something similar. It may have a clock icon next to it. On some remotes, this button is used to both set and cancel the timer.

Step 2: Press the Timer Button

Press the “Timer” button once. This usually brings up the current timer settings on the AC’s display panel. If a timer is active, you’ll see a time or countdown displayed.

Step 3: Cancel the Timer

To turn off the timer:

• Press and hold the “Timer” button for 3–5 seconds until the timer display disappears.
• Alternatively, press the “Cancel” or “Clear” button if your remote has one.
• On some models, pressing the “Timer” button repeatedly cycles through options—keep pressing until “Off” or “—:—” appears.

Step 4: Confirm the Timer Is Off

Check the display on your air conditioner. If the timer is successfully turned off, the timer icon (usually a clock or bell symbol) should no longer be lit. The unit will now operate based on manual settings only.

Example: Turning Off Timer on an LG Dual Inverter Window AC (2026 Model)

Let’s say you have an LG Dual Inverter Window Air Conditioner, model LW1822IVSM (a popular 2026 release). Here’s how you’d turn off the timer:

1. Point the remote at the AC unit.
2. Press the “Timer” button—you’ll see “Timer On” or a scheduled time appear on the display.
3. Press and hold the “Timer” button for 4 seconds.
4. The display will show “—:—” and the timer icon will disappear.
5. The AC will now run continuously based on your temperature and fan settings.

How to Turn Off Timer Using the AC Control Panel

Not all LG air conditioners come with a remote—especially older window units or basic portable models. If you don’t have a remote or it’s not working, you can still turn off the timer using the control panel on the unit itself.

Step 1: Locate the Control Panel

Find the control panel on the front or top of your air conditioner. It usually has buttons for power, mode, temperature, fan speed, and timer.

Step 2: Access the Timer Menu

Press the “Timer” or “Function” button. On some models, you may need to press and hold it for a few seconds to enter the timer settings.

Step 3: Navigate to Timer Off

Use the “+” or “-” buttons (or arrow keys) to scroll through timer options. Look for “Timer Off,” “Cancel,” or a blank time setting.

Step 4: Confirm and Exit

Once you’ve selected “Off,” press the “Set” or “OK” button to confirm. The timer icon on the display should disappear.

Tip: Use the Power Button Trick

If the timer won’t turn off through the menu, try this quick fix:

• Turn off the AC using the power button.
• Wait 10 seconds.
• Turn it back on.

This often resets temporary settings, including the timer.

How to Turn Off Timer on LG Smart Air Conditioners (2026 Models)

In 2026, many LG air conditioners are “smart” models that connect to Wi-Fi and can be controlled via the LG ThinQ app. These units—such as the LG Art Cool Mirror or LG Dual Inverter Smart Window AC—offer advanced timer features, including scheduling through your smartphone.

Step 1: Open the LG ThinQ App

Make sure your phone is connected to the same Wi-Fi network as your AC. Open the LG ThinQ app (available on iOS and Android).

Step 2: Select Your Air Conditioner

Tap on your AC unit from the home screen. You’ll see current settings like temperature, mode, and timer status.

Step 3: Access the Timer Settings

Look for a “Schedule” or “Timer” tab. Tap it to view active timers.

Step 4: Turn Off or Delete the Timer

You’ll see a list of scheduled on/off times. To turn off a timer:

• Tap the toggle switch next to the active timer to disable it.
• Or, swipe left on the timer entry and select “Delete.”

Step 5: Confirm Changes

The app will sync with your AC. Check the unit’s display to ensure the timer icon is gone.

Bonus: Disable All Schedules

To prevent future issues, go to “Settings” > “Automation” and turn off “Auto Schedule” or “Smart Timer.” This ensures no timers activate without your knowledge.

How to Turn Off Timer on Portable LG Air Conditioners

Portable LG air conditioners, like the LG LP1419IVSM, often have simpler controls but still include timer functions. Here’s how to disable the timer on these units.

Step 1: Check the Remote or Control Panel

Most portable models come with a remote. If not, use the buttons on the unit.

Step 2: Press the Timer Button

Press the “Timer” button once. The display will show the current timer setting (e.g., “2H” for 2 hours).

Step 3: Cancel the Timer

Press the “Timer” button again until the display shows “0H” or the timer icon turns off. On some models, you may need to press and hold the button.

Step 4: Verify

The AC should now run continuously. If the timer reactivates, try removing the remote batteries for 30 seconds to reset the signal.

Troubleshooting: What to Do If the Timer Won’t Turn Off

Sometimes, despite following the steps, the timer refuses to disable. Here are common issues and fixes.

Issue 1: Remote Not Responding

• Check the batteries: Weak batteries can cause signal issues. Replace them with fresh AAA or AA batteries.
• Clean the remote: Dust or moisture can block the infrared sensor. Wipe it with a dry cloth.
• Ensure line of sight: Point the remote directly at the AC’s receiver (usually on the front panel).

Issue 2: Timer Keeps Reactivating

This could be due to:

• Accidental button presses: Place the remote in a safe spot or use a remote lock feature if available.
• Smart schedule enabled: Check the LG ThinQ app for recurring schedules and disable them.
• Firmware glitch: Update your AC’s firmware via the app or LG’s support website.

Issue 3: Display Shows Timer but Unit Isn’t Following It

This suggests a software or sensor issue. Try:

• Power cycling: Turn off the AC at the wall outlet, wait 1 minute, then turn it back on.
• Factory reset: Consult your user manual for reset instructions (usually involves holding multiple buttons).

Issue 4: No Timer Button on Remote or Unit

Some basic models don’t have a timer function. If you’re seeing a timer icon, it might be a different feature (like sleep mode). Check your model number in the LG support database to confirm.

Preventing Accidental Timer Activation

Now that you know how to turn off the timer, here’s how to stop it from happening again.

Use Remote Lock

Many LG remotes have a “Lock” or “Child Lock” feature. Activate it to prevent accidental button presses. Look for a lock icon or hold the “Mode” and “Fan” buttons together for 3 seconds.

Disable Smart Schedules

In the LG ThinQ app, go to your AC settings and turn off “Auto Schedule” or “Smart Timer.” This stops the app from creating timers based on your habits.

Educate Household Members

Make sure everyone in your home knows how the timer works—and how to turn it off. A quick demo can prevent midnight AC surprises.

Label the Remote

Use a small sticker or label to mark the “Timer” button. This helps avoid confusion, especially for guests or children.

When to Contact LG Support

If you’ve tried all the steps and the timer still won’t turn off, there may be a hardware or software issue. Contact LG Customer Support if:

• The display is frozen or unresponsive.
• The remote doesn’t work even with new batteries.
• The AC turns on/off at random times despite no timer being set.
• You suspect a firmware bug in your 2026 model.

You can reach LG support via:

• Phone: 1-800-243-0000 (U.S.)
• Live chat on lg.com
• LG ThinQ app support section

Have your model number and serial number ready—they’re usually on a sticker inside the front panel or on the back.
