Which outcome occurs when a microwave oven operates with no load inside it?

💡 Explanation

When a microwave operates with no load, microwave energy reflects back into magnetron because there is nothing to absorb it, causing it to overheat because of increased power dissipation within tube. Therefore magnetron overheating occurs from reflected power, rather than arcing, saturation or malfunction which involve completely separate failure modes.
