Lfx31925st/02 Parts

The PCB Assembly, Sub is an OEM part for LG refrigerators. It assists the main control board by regulating secondary refrigerator functions such as dispenser controls, ice makers, and temperature displays in specific refrigerator sections. Located inside exterior access panels, the sub board receives inputs and routes outputs behind refrigerator side panels and doors.

Causes of a bad sub board can include water damage to electronic components leading to shorts, as well as failure over many freeze-thaw cycles. 

Symptoms of a bad PCB Assembly, Sub include:

• Ice maker or water dispenser not operating 
• Incorrect temperature reading for sections  
• Error codes appearing on exterior display
• Buzzing or humming sounds from interior panels
