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

Outcome

A Hacker News commenter's gas dryer ran but wouldn't heat. Gemini suggested a thermal fuse, pointed it out in a photo of the opened back panel, walked him through testing it, linked the part once he gave the model number, and advised cleaning the vent since poor venting likely blew the fuse. He says after cleaning the exhaust and a $5 fuse the dryer works fine.

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

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Find out why my dryer runs but doesn't heat, test the likely part, and order the right replacement.

Fill in before running:
- Dryer brand and model number: [MODEL]
- Gas or electric: [TYPE]
- Symptom: [e.g. drum turns, no heat, started after X]
- Photo of the back panel once removed (unplugged first)
- Tools: [multimeter yes/no]

Safety first: unplug the dryer or switch it off at the breaker before any panel comes off. Don't have me touch the gas valve, gas line, burner or flame area, or the electrical panel, and don't have me disconnect or alter the venting (cleaning lint out of the duct is fine). If I smell gas, tell me to leave the house right away and call the gas utility or a licensed technician.

Rules:
- Unplug the dryer (and for gas, don't touch the gas line or burner) before any panel comes off.
- Identify the thermal fuse and other heat-related parts in my photo and describe where each is.
- Explain how to test the fuse for continuity and what reading means it's blown.
- Find the exact part number for my model and a reputable seller.
- If the fuse blew, check the venting: tell me how to clean the lint path and duct.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: Steps with what to test, the part number and price, and the vent-cleaning steps.

You'll know it worked when: the part I order matches my model and the dryer heats after the fix and vent clean.

- If the fuse tests fine, give me the next two parts to test in order (cycling thermostat, igniter) before suggesting 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.
