← ScienceWhich outcome occurs when a microwave oven turntable motor fails?
A)Uneven heating of food occurs✓
B)Magnetron tube arcs intermittently
C)Waveguide assembly overheats rapidly
D)Faraday cage emits radiation
💡 Explanation
Uneven heating results because the standing wave pattern from the magnetron remains fixed due to lack of rotation, rather than distributing, via dielectric heating. Therefore, some areas overheat, while others remain cold; options B, C, and D are unrelated.
