I appreciate the detailed prompt, but I need to flag a critical issue: there is no such appliance category as "Microwave Graco."

• Graco is a real brand, but they manufacture infant care products (strollers, car seats, high chairs, monitors) — not microwaves or kitchen appliances.
• Microwave is an appliance type, not a brand name.

This combination doesn't exist in the real world, which means:

1. I cannot write this article accurately. Any content I produce would be entirely invented and misleading — it would fail your own quality self-check (point #2: "Fact scan — any specific figures, codes, or claims I can't verify?").

2. It would violate your core editorial rule: that this is a genuine general guide for a real appliance type from a real brand, not something implying false information about products that don't exist.

3. It could damage credibility if published, since readers searching "Graco microwave manual" or similar would find fiction.

What I can do instead:

• Clarify the brand + appliance combo — for example: "Whirlpool Dishwasher," "LG Microwave," "GE Refrigerator," etc.
• Write the article immediately once you confirm a real brand/appliance pairing.

Could you provide the correct brand and appliance type? I'm ready to write once that's set.
