How to Clear Error Codes on Your LG Refrigerator

Dimitri VolkovskiySetup & Efficiency Writer

What an error code means and how to reset it

An error code on your LG refrigerator display tells you something is not working as it should — a sensor has stopped responding, a door has been open too long, or a component needs attention. The code itself is useful information; resetting it clears the message from the screen, but it does not fix the underlying problem. Most error codes reset on their own once you address what triggered them, or you can manually clear the display using your refrigerator's control panel.

The reset process takes less than a minute and requires no tools. You will use buttons on the refrigerator's front panel to access the control settings, find the reset or clear option, and confirm. If the same error code returns immediately after you reset it, the problem still exists and you will need to troubleshoot the specific issue.

Key Takeaways

  • Most LG refrigerator error codes reset automatically once the problem is resolved, such as closing a door that was left ajar or waiting for the compressor to cycle.
  • You can manually clear an error code by holding the Power Cool and Power Freeze buttons together for three to five seconds, or by pressing the Settings button and navigating to Reset.
  • The exact reset method depends on your model — check your user manual or the control panel layout to identify which buttons to use.
  • If an error code returns immediately after you reset it, the underlying cause has not been fixed and resetting will not solve it.
  • Common codes like C1 (door sensor), C5 (temperature sensor), and E1 (compressor) point to specific parts that may need service.

Locate your control panel and identify the reset buttons

Your LG refrigerator's control panel is mounted on the front of the unit, usually at eye level on the right side of the top section. The panel displays the current temperature, any active error codes, and has between three and six touch buttons or physical buttons depending on your model year and style.

Look for buttons labeled Power Cool, Power Freeze, Settings, or Menu. These are the buttons you will use to reset. If your panel has a small icon that looks like a gear or wrench, that is often the Settings button. Write down the exact button names you see — this matters because different LG models use slightly different layouts, and using the wrong button will not trigger the reset.

Reset using the Power Cool and Power Freeze buttons

This is the fastest method on most LG refrigerators. Locate the Power Cool button and the Power Freeze button on your control panel. Press and hold both buttons at the same time for three to five seconds. You will hear a beep or see the display flash, which signals that the reset is in progress.

Release both buttons and wait a few seconds for the display to return to normal. The error code should be gone. If the display still shows the code, try holding the buttons for a full five seconds — some models require a longer press. If the code clears but returns within a few minutes, the problem that triggered it is still active and needs to be addressed before the code will stay cleared.

Reset through the Settings menu

If the Power Cool and Power Freeze method does not work on your model, use the Settings menu instead. Press the Settings button (or Menu button on some models) once. The display will show a list of options, which may include Temperature, Lighting, Reset, or Diagnostics.

Use the up and down arrow buttons to scroll through the menu until you see Reset or Clear Error. Press the button next to that option to confirm. The display will ask you to confirm the reset — press the confirmation button (usually labeled OK or Yes). The error code will clear and the display will return to the normal temperature screen.

Some LG models label this option as Diagnostics or Service Mode instead of Reset. If you do not see a Reset option in the Settings menu, check your user manual for your specific model number — the exact menu structure varies.

Address the problem that triggered the error code

Resetting the display clears the message, but the refrigerator will show the same error code again if the underlying issue is not resolved. Common error codes and their causes include:

  • C1 or C2: Door sensor problem — make sure the door closes fully and the seal is not cracked or dirty.
  • C5: Temperature sensor not responding — this usually requires service, as the sensor may need replacement.
  • E1: Compressor issue — the compressor may be cycling on and off too quickly, or it may have failed.
  • E3: Freezer temperature too high — check that the vents between the fridge and freezer are not blocked by ice or food.
  • E8: Water supply problem — if your model has an ice maker or water dispenser, check that the water line is connected and not frozen.

If the error code is related to a door or vent, fix that first and then reset. If the code is related to a sensor or compressor, the refrigerator will need professional service — resetting will only clear the message temporarily. Do not ignore a code that returns immediately; it is a sign that something needs attention.

When to reset versus when to call for service

Reset the error code yourself if it appears once and does not return, or if it is clearly tied to something you can fix — a door left open, a vent blocked by ice, or a water line that came loose. These are temporary conditions, and once you fix them, the code will not come back.

Call an LG service technician or a may have access to refrigerator repair person if the error code returns within hours of resetting it, if you see the same code multiple times a week, or if you cannot identify what caused it. Codes related to sensors (C5, E1) or compressor function almost always require professional diagnosis and repair. Attempting to reset a recurring code repeatedly will not fix it and may delay getting the help you need.

Frequently Asked Questions

Will resetting the error code fix the problem?

Resetting clears the message from the display but does not repair the underlying issue. If the problem still exists, the code will return. Reset only clears the display; you must address what caused the error for it to stay cleared.

What if I do not know which buttons to press?

Check your user manual — it will show the exact button layout and reset procedure for your model. You can also find the manual online by searching for your model number (printed on a sticker inside the fridge or on the back). If you cannot locate the manual, try the Power Cool and Power Freeze button method first, as it works on most LG models.

Can I reset the refrigerator by unplugging it?

Unplugging the refrigerator for a few minutes will reset the control panel and clear error codes, but it will also interrupt cooling and may cause food safety issues if left unplugged too long. Use the button method instead — it is faster and does not risk your food.

Why does the same error code keep coming back?

A recurring code means the problem has not been fixed. Resetting the display over and over will not solve it. Identify what the code means (check your manual or the list above), address that specific issue, and then reset. If you cannot fix it yourself, contact a repair technician.

Is it safe to use the refrigerator while an error code is showing?

It depends on the code. A door sensor code (C1, C2) means the fridge may not be cooling properly, so food safety is at risk. A compressor code (E1) means cooling may be failing. Other codes may not affect cooling immediately. If you are unsure, do not wait — reset the code and monitor the temperature. If the code returns and the fridge is not cooling, stop using it and call for service.
