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
