LG Refrigerator beeping/alarm sounding
If your refrigerator is beeping or the refrigerator alarm is beeping with the door closed, start by checking the display for a fault code and consult the owner’s manual for what that code means. A common cause is a recent power outage that left the unit in a fault state; try turning the breaker off for a few minutes and back on to reset the fridge. If the beeping continues, a faulty door switch is a likely culprit—if the switch tells the control board a door is open when it is closed the alarm will sound; you can test the switch for continuity with a multimeter and replace it if it fails. When cooling is normal and the door switch checks out, the problem often lies in electronics: the dispenser control board, the user control and display board, or the main control board can produce intermittent beeps or alarms. If you need parts, enter your model number on RepairClinic.com to find the exact replacement refrigerator parts for your model and get step by step repair guidance.
01 - Check Fault Codes
When a refrigerator is beeping, a fault code will usually be displayed to help diagnose the issue. Refer to the owner's manual or do an on-line search for fault code designations and possible solutions.

02 - Power outage reset
After a power outage the refrigerator display will typically beep and/or flash a code like PO for power outage or PF for power failure. Try turning the breaker off for a few minutes then back on to reset the refrigerator or refer to the owner's manual for specific resetting information.
Highly Likely
03 - LG Refrigerator Door Switch
A refrigerator door switch is used to turn on the interior lights when a door is opened and to ensure the door with a water and ice dispenser is closed before dispensing ice. If the switch is defective, it may signal to the control that a door is open even when it is fully closed resulting in a beeping alarm sound. You can use a multimeter to test the door switch for appropriate electrical continuity. If the switch does not test appropriately, it should be replaced.

04 - LG Refrigerator Dispenser Control Board
If the refrigerator is cooling properly and the door switch is functioning normally, a faulty dispenser control board could be the cause of the beeping noise. Replace the old control board with a new one to see if that resolves the problem.
Less Common
05 - LG Refrigerator User Control and Display Board
To determine if the user control and display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the user control and display board might need to be replaced. Additionally, if the display is not working, check the power to the user control and display board. If the user control and display board has power, but it isn’t working, replace it.
Less Common
06 - LG Refrigerator Control Board
If the refrigerator is cooling properly and the door switch is functioning normally, a faulty control board could be the cause of the beeping noise. Replace the old control board with a new one to see if that resolves the problem.
