Method:

How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Beginner-friendlyNo logins, payments or coding needed. Low risk: paste the prompt and you should get something useful.

Outcome

When a freezer stopped working, Marc Landers gave Grok the make, model and problem. Grok had them turn on voice and camera mode, open the door, remove the top hinge cover (no tools needed) and point the camera at a wire it said was a known fault for that model. Grok gave the price and an Amazon link for the part; the £10 wire arrived next day and took five minutes to replace, instead of paying a repair technician.

The source didn't share its exact prompt, so we wrote this from what it describes.

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Help me find out why my appliance stopped working, using my phone camera, and whether it's a cheap part I can replace.

What I can give you (ask for whatever's missing):
- Make and model
- What stopped working and when
- Anything I've already checked

Safety first: if this involves gas, the electrical panel or mains wiring, structural work, or anything that smells of burning or gas, stop and tell me to call a licensed professional.

Rules:
- Guide me one step at a time and wait for me to show you each area on camera.
- Tell me to unplug it before I remove any cover.
- If you suspect a known fault, say how sure you are and where that's documented.
- Give me the exact part name or number so I can check it matches before buying.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: The likely cause, the part to buy, and simple replacement steps.

You'll know it worked when: the appliance works again without a call-out fee.

- If it isn't a simple part swap, tell me plainly to call a technician.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
