How to Reset Your LG Refrigerator to Factory Settings

When and Why to Reset Your LG Refrigerator

A factory reset returns your LG refrigerator to its original settings—the temperature, ice maker status, water dispenser settings, and any custom modes you've adjusted. You'll want to reset when the refrigerator isn't responding to button presses, when settings keep changing on their own, after a power outage that left the display frozen, or when you're troubleshooting an error code that won't clear.

A reset is not the same as unplugging the unit. Unplugging clears temporary glitches but doesn't restore the control board to factory defaults. A true reset wipes the memory of all your changes and brings every setting back to what LG programmed at the factory.

Most resets take less than a minute and require nothing but your hands and the control panel. Some models have a dedicated reset button; others use a button combination. The exact method depends on your model number, which you'll find on a sticker inside the refrigerator compartment or on the back wall.

Key Takeaways

• Locate your LG model number on the interior wall or back of the unit before you start, because reset methods vary by model.
• Most LG refrigerators reset by holding the Ice Plus and Freezer buttons together for three to five seconds until the display flashes or beeps.
• After a reset, the refrigerator returns to 37°F for the fridge and 0°F for the freezer, and you'll need to adjust temperature again if those aren't your preferred settings.
• If the display still shows an error code after reset, the problem is likely a sensor or control board fault that requires service.

Finding Your Model Number and Manual

Your LG model number is printed on a white or silver sticker, usually on the interior wall of the refrigerator compartment (look on the side wall or top), or on the back exterior of the unit. It starts with letters like "LRMVS" or "LRFVS" followed by numbers. Write this number down or take a photo—you'll need it to find the exact reset procedure for your specific refrigerator.

Once you have the model number, go to LG's support website and search for your model. Download the Owner's Manual PDF. The manual contains the reset instructions specific to your control panel. If you can't find the manual online, call LG Customer Service at 1-800-243-0000 and provide your model number; they can walk you through the reset or email you the manual.

The reason this matters: LG has made dozens of control panel designs over the years. Some have a dedicated Reset button. Others use button combinations. A few older models require you to hold a specific button for 10 seconds. Using the wrong method won't harm the refrigerator, but it won't reset it either.

The Most Common Reset Method

On the majority of LG refrigerators made in the last ten years, the reset works like this: locate the Ice Plus button and the Freezer button on your control panel. Press and hold both buttons at the same time for three to five seconds. You'll see the display flash, hear a beep, or watch the lights blink—this signals the reset is working.

Release the buttons and wait 10 seconds. The display may go blank briefly, then return to normal. The refrigerator is now reset to factory settings. The temperature will show 37°F for the fridge compartment and 0°F for the freezer. If you prefer different temperatures, adjust them now using the temperature buttons.

If nothing happens after holding the buttons for five seconds, try these variations: some models require you to hold for 10 seconds instead, or to press the buttons in a different order (Freezer first, then Ice Plus). Check your manual for the exact timing. If you still see no response, the control panel may not be receiving power, or the buttons themselves may be stuck.

Alternative Reset Methods by Control Panel Type

Some LG models have a dedicated Reset button, usually located on the far left or right of the control panel, sometimes labeled "Reset" or "Rst". Press and hold this button for three to five seconds until the display resets. This is the simplest method and leaves no room for confusion.

Older LG refrigerators or models with simpler displays may require you to hold down a single button—often the Power Cool or Power Freeze button—for 10 to 15 seconds. The display will flash or the lights will dim, signaling the reset. Release the button and wait for the display to stabilize.

If your refrigerator has a touchscreen display rather than physical buttons, the reset may be buried in a menu. Press the Menu or Settings button, navigate to "Reset" or "Factory Reset" using the arrow buttons, and confirm. Touchscreen models vary widely, so your manual is essential here. If you've lost the manual and can't find it online, LG support can email it to you within one business day.

What Happens After the Reset

Immediately after a successful reset, your refrigerator will return to these factory defaults: fridge temperature at 37°F, freezer at 0°F, ice maker on (if your model has one), water dispenser on, and any custom modes or schedules cleared. If you had set the fridge to 34°F or the freezer to -5°F, those changes are gone and you'll need to set them again.

The reset does not affect ice already in the ice maker, water in the dispenser lines, or food in the compartments. It only clears the settings stored in the control board's memory. Your food stays cold, and the refrigerator continues running without interruption.

If you had an error code displayed before the reset (like "Er FF" or "Er IF"), the code should disappear. If it returns within a few minutes, the underlying problem—usually a sensor malfunction or control board issue—is still present and will need professional service. A reset clears the code from memory but doesn't fix a broken sensor.

Troubleshooting a Reset That Doesn't Work

If you've held the buttons for the full time and nothing happened, first check that the refrigerator is plugged in and the outlet has power. Plug a lamp or phone charger into the same outlet to confirm. If the outlet is dead, reset the circuit breaker in your home's electrical panel and try again.

Next, make sure you're pressing the correct buttons. Look at your control panel and verify the button labels. Some buttons are small or have faint labels. If the buttons feel stuck or don't click when pressed, they may be physically jammed. Try pressing them several times firmly to free them up, then attempt the reset again.

If the display is completely dark and unresponsive, unplug the refrigerator for five minutes, then plug it back in. This performs a hard reset and often restores power to the control board. Wait for the display to light up, then try the reset procedure again. If the display remains dark after this step, the control board may have failed and will need replacement by a service technician.

Resetting After a Power Outage

Power outages sometimes leave the control board in a confused state, with the display frozen, buttons unresponsive, or error codes stuck on screen. A factory reset is often the fastest way to clear this. Follow the reset procedure for your model as described above.

If the reset doesn't work after an outage, unplug the refrigerator for 30 minutes to allow the control board to fully discharge. This is longer than the usual five-minute wait and gives capacitors time to drain completely. Plug it back in, wait for the display to stabilize (usually 30 seconds to two minutes), then try the reset again.

After a power outage, your refrigerator may also show error codes related to temperature sensors or ice maker sensors. These codes often clear on their own within 24 hours as the sensors recalibrate. If an error code persists after a reset and a full 24-hour wait, the sensor itself may have been damaged by the power surge and will need replacement.

Frequently Asked Questions

Will resetting my LG refrigerator erase my saved settings like temperature preferences?

Yes. A factory reset erases all custom settings and returns the refrigerator to LG's original defaults: 37°F for the fridge, 0°F for the freezer, and all features turned on. You'll need to adjust the temperature and any other settings again after the reset completes.

How long does a reset take?

The button-holding part takes three to five seconds. After you release the buttons, wait 10 to 30 seconds for the display to stabilize and the reset to complete. The entire process is usually done within one minute. If the display is still frozen after two minutes, unplug the unit for five minutes and try again.

Can I reset my LG refrigerator if it's still plugged in?

Yes. You do not need to unplug the refrigerator to perform a reset. The reset procedure works with the unit powered on and running. Only unplug if the display is completely dark or unresponsive, or if you're performing a hard reset after a power outage.

What if the reset button or button combination doesn't work?

First, verify you have the correct model number and are using the right reset method for that model. Check your manual or call LG support at 1-800-243-0000 with your model number. If the buttons don't respond at all, the control panel may not be receiving power. Unplug the refrigerator for five minutes, plug it back in, and try again. If the display remains unresponsive, the control board likely needs professional service.

Do I need to reset my refrigerator after changing the water filter?

No. Changing the water filter does not require a reset. Some LG models have a "Reset Filter" button on the control panel that you press after installing a new filter—this just clears the filter-life counter. This is different from a factory reset and does not affect temperature or other settings.
