Why do modern appliance control boards fail so fast?

Modern appliance control boards frequently fail prematurely due to vulnerability in delicate electronic components and wiring harnesses, often rendering expensive refrigerators, dryers, and dishwashers entirely unusable. Technicians trace these recurring electrical failures directly to specific design weaknesses, forcing homeowners to face costly replacements or scrap units that should last for years.
