• User Alerts: Many modern boards come equipped with diagnostic alerts, informing you of issues before they escalate.

Weaknesses:

• Complexity: Their intricate systems can be sensitive to electrical surges and malfunctions.
• Replacement Costs: If the control board fails, replacement can be costly, often requiring professional assistance.
• Limited Lifespan: Like any electronic component, they have a finite lifespan, often necessitating repairs or replacement down the line.
