Over-the-range microwave malfunctions are expensive to diagnose and repair, forcing homeowners into costly replacement cycles

Homeowners with aging over-the-range microwaves (10+ years old) face mysterious electrical failures like fans activating unexpectedly, with no clear DIY solutions available. Repair technicians are expensive and often unavailable for older models, while replacement costs $300-800+. Current solutions fail because manufacturers discontinue parts, repair guides are sparse, and homeowners lack technical knowledge to troubleshoot electrical issues safely.
