Before we get into the steps, it’s worth understanding why using the timer is such a smart move. In 2026, energy efficiency isn’t just about saving money—it’s about reducing your carbon footprint and making your home smarter.
The timer function allows you to:
– Cool your room just before you arrive home.
– Turn off the AC automatically after you fall asleep.
– Avoid overcooling empty rooms.
– Reduce wear and tear on the compressor by limiting runtime.
For example, imagine coming home from work on a hot summer afternoon. Instead of walking into a stuffy house and waiting 30 minutes for it to cool down, you set the On Timer to start cooling 20 minutes before you arrive. Your home is perfectly comfortable the moment you walk through the door—and you didn’t waste energy all day.
Similarly, many people leave their AC running all night “just in case,” but that’s inefficient. With the Off Timer, you can set it to turn off at 2 a.m., saving power while you’re deep in sleep and less sensitive to temperature changes.
What You’ll Need Before Starting
Setting the timer on your LG air conditioner is straightforward, but a few things will make the process smoother:
- Original LG remote control: Most timer functions are accessed via the remote. If you’ve lost it, check if your model supports a replacement or smartphone app.
- Fresh batteries: Weak batteries can cause unresponsive buttons or failed commands.
- AC power and operation: Make sure your unit is plugged in and functioning normally.
- Correct time set on the AC: The timer relies on the internal clock. If it’s wrong, your scheduled times won’t match reality.
If your LG model is Wi-Fi enabled (look for “LG ThinQ” compatibility), you’ll also benefit from having the LG ThinQ app installed on your smartphone and your AC connected to your home Wi-Fi network.
Step-by-Step: How to Set the Off Timer on Your LG Air Conditioner
The Off Timer is perfect for turning your AC off automatically after a set period—ideal for nighttime use or when you’re stepping out briefly.
Step 1: Turn On Your Air Conditioner
Press the Power button on your remote to turn on the unit. Wait for it to start cooling or heating, depending on your setting.
Step 2: Locate the Timer Button
Look for the Timer button on your remote. It’s usually labeled clearly and may have a clock icon. On some newer models, it might be part of a menu accessed via the “Function” or “Menu” button.
Step 3: Enter Timer Mode
Press the Timer button once. The display on your remote or AC unit should show “OFF TIMER” or a similar message. Some models will flash the current timer setting or show “–:–” if no timer is set.
Step 4: Set the Delay Time
Use the ▲ (Up) and ▼ (Down) arrows to adjust the time. You can typically set the Off Timer in 30-minute increments, up to 12 hours. For example:
– Press ▲ to set it to 2 hours if you want the AC to turn off after 2 hours.
– If you want it off at a specific clock time (e.g., 11:30 p.m.), make sure your AC’s internal clock is correct (we’ll cover that next).
Step 5: Confirm the Setting
Once you’ve selected the desired time, press the Timer button again to confirm. The display should stop flashing and show the set time. A small timer icon may appear on the AC’s display panel to indicate the Off Timer is active.
Step 6: Test It
Wait and observe. After the set time passes, the AC should automatically turn off. If it doesn’t, double-check your settings or try resetting the remote.
Step-by-Step: How to Set the On Timer on Your LG Air Conditioner
The On Timer lets you schedule your AC to turn on at a specific time—great for coming home to a cool house or waking up in a comfortable bedroom.
Step 1: Ensure the AC Is Off
The On Timer only works when the unit is currently off. If it’s running, turn it off using the Power button.
Step 2: Press the Timer Button
Press the Timer button on your remote. Look for “ON TIMER” to appear on the display.
Step 3: Set the Start Time
Use the arrow buttons to set the time you want the AC to turn on. Again, this is usually in 30-minute intervals. For example:
– If it’s 3:00 p.m. and you want the AC on at 5:30 p.m., set the On Timer to 2.5 hours.
– Alternatively, if your AC’s clock is accurate, you can set it to a specific time like 6:00 a.m.
Step 4: Confirm and Activate
Press the Timer button again to lock in the setting. The On Timer icon should appear, indicating the schedule is active.
Step 5: Wait and Verify
At the scheduled time, your LG air conditioner should power on automatically. Make sure it starts cooling or heating as expected.
How to Set Both On and Off Timers (24-Hour Schedule)
Many LG models allow you to set both timers simultaneously, creating a full daily schedule. This is especially useful for consistent routines.
Step 1: Set the On Timer First
Follow the On Timer steps above to schedule when the AC should turn on.
Step 2: Set the Off Timer
After confirming the On Timer, press the Timer button again to switch to Off Timer mode. Set the desired shut-off time.
Step 3: Confirm Both Settings
Press the Timer button once more to save both timers. The display should show both icons or times.
Example Scenario
Let’s say you leave for work at 8:00 a.m. and return at 6:00 p.m. You can:
– Set the Off Timer to turn the AC off at 8:30 a.m.
– Set the On Timer to turn it back on at 5:40 p.m.
This way, your home stays comfortable when you’re there—and saves energy when you’re not.
Using the LG ThinQ App for Smart Timer Control (2026 Models)
If your LG air conditioner is Wi-Fi enabled and compatible with the LG ThinQ app (available for iOS and Android), you can control timers remotely—no remote needed!
Step 1: Download and Install LG ThinQ
Search for “LG ThinQ” in your app store and install it. Create an account or log in if you already have one.
Step 2: Add Your Air Conditioner
Open the app and tap the “+” icon to add a new device. Follow the on-screen instructions to connect your AC to your Wi-Fi network. You may need to press a pairing button on the unit or remote.
Step 3: Access Timer Settings
Once connected, tap on your AC from the home screen. Look for “Schedule” or “Timer” in the menu.
Step 4: Create a Custom Schedule
You can set multiple On/Off times per day, adjust temperatures, and even create weekly routines. For example:
– Monday–Friday: Cool to 72°F from 5:30 p.m. to 11:00 p.m.
– Weekends: Cool from 9:00 a.m. to 10:00 p.m.
The app also sends notifications when timers activate, so you’re always in control.
Bonus: Voice Control
With LG ThinQ, you can also use voice commands via Google Assistant or Amazon Alexa. Say, “Hey Google, turn on the living room AC at 6 p.m.,” and it’ll schedule it automatically.
How to Check and Set the Correct Time on Your LG AC
For timers to work accurately, your AC’s internal clock must match real time. Here’s how to sync it:
Step 1: Press the Clock Button
On most LG remotes, there’s a Clock button. Press it to enter time-setting mode.
Step 2: Adjust Hours and Minutes
Use the ▲ and ▼ arrows to set the correct hour and minute. Some models let you toggle between 12-hour and 24-hour formats.
Step 3: Confirm the Time
Press the Clock button again to save. The display should stop flashing.
Tip: Sync with Internet Time (Smart Models)
If your AC is connected to Wi-Fi via ThinQ, the clock may sync automatically with internet time servers—no manual adjustment needed.
Troubleshooting Common Timer Issues
Even with clear instructions, things can go wrong. Here’s how to fix the most common problems:
Timer Doesn’t Activate
- Check power: Ensure the AC is plugged in and the outlet has power.
- Replace remote batteries: Weak batteries are a frequent culprit.
- Reset the remote: Remove batteries for 30 seconds, then reinsert.

AC Turns On/Off at the Wrong Time
- Recheck the clock: If the internal time is off, timers will be too.
- Daylight saving time: Remember to adjust the clock when DST changes.
- Power outage: A recent outage may have reset the clock.
Remote Not Responding
- Clean the IR sensor: Dust on the remote or AC sensor can block signals.
- Check distance and angle: Stand within 20 feet and aim directly at the unit.
