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 dryer took three hours to dry a load (normally 45 minutes), Lisa-Anne Chung showed ChatGPT the model number, the parts that weren't working and the pipes at the back over a video chat. It identified the model from a photo, walked Chung through checks such as whether the burner glowed and listening for clicks, gave a shortlist of likely causes, and suggested Sunnyvale repair companies via Yelp with a fair diagnostic fee. Chung says they had a solid hypothesis in about 10 minutes and could talk knowledgeably when they called a repair company.

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 narrow down why my dryer isn't drying, using my camera, so I know what to tell a repair company.

What I can give you (ask for whatever's missing):
- Dryer brand and model number (photo of the label)
- Gas or electric
- What's happening (how long a load takes, any noises or smells)
- My city, for finding repair companies

Safety first: on a gas appliance, don't have me touch the gas valve, burner or venting; if I smell gas, tell me to leave and call the gas company. Unplug or switch off at the breaker before any panel comes off.

Rules:
- Ask me to show you the label first and confirm the model before suggesting checks.
- Only suggest checks I can do safely by looking or listening; no taking panels off a gas dryer.
- After each check, tell me what the result rules in or out.
- Give me a short list of likely causes and a fair diagnostic fee range to expect where I live.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A shortlist of likely causes, what I saw that points to each, and a few repair companies to call.

You'll know it worked when: I can describe the fault to a repair company in two sentences and know if a quote sounds off.

- Tell me plainly which causes are a job for a technician rather than me.

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