Maintenance & Diagnostic Analysis
A systematic way to narrow “what broke” without guessing.
Start with user-reproducible symptoms: no heat, intermittent noise, unusual odor, or sparking. Verify power supply, door closure, and interlock behavior before opening enclosures. For consumer-safe first checks, see Maintenance & Troubleshooting and Basic Troubleshooting Guide . For RF generation theory, see Magnetron Technology Deep Dive .
Diagnostic Tree (High Level)
- Confirm controls and settings (timer vs. cook).
- Inspect door, seals, and interior for damage.
- If sparking: remove metal; inspect waveguide cover.
- If no heat: suspect RF chain or control; professional service.
