What the prompt labels mean

Our fuller version of the person's prompt. They didn't use this version, and we haven't tested it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Help me find out why my fridge isn't holding temperature and whether I can safely fix it myself.

Questions to ask me first:
- What's the brand, model number and age of the fridge?
- What temperatures are the fridge and freezer showing, and since when?
- Do you have a multimeter and basic tools, and are you comfortable unplugging and moving the fridge?

Inputs (fill in or confirm):
- Brand, model and serial number: [MODEL / SERIAL]
- Fridge and freezer temperatures: [TEMPS]
- What I've noticed (frost, water, noises, smells): [SYMPTOMS]
- Tools I have: [TOOLS]

Rules:
- Start with the simple checks (door seals, vents, condenser coils, settings) before anything that needs panels removed.
- Tell me to unplug the fridge before any step that opens a panel or tests a part.
- Explain each multimeter test and the reading that means a part has failed.
- Don't give me part numbers as final; tell me to confirm them for my exact model and serial number on the maker's or a parts site.
- Tell me when the problem needs a technician, such as sealed-system or compressor issues.

Checkpoint: After the simple checks, ask me what I found before moving to the defrost system.

If you get stuck: If my symptoms fit more than one cause, list them from most to least likely and how to tell them apart.

Verify before you finish: Check that the parts you suggest match the failed test, not just the symptom.

Output: Numbered steps, the test results that point to each part, and a rough DIY cost versus a service call.

Done when: I know which part failed, have confirmed the right part number, or know it's time to call a technician.

Outcome

Gary Deckerd's refrigerator felt warm and humid, reading around 48°F while the freezer was fine. Deckerd told ChatGPT the fridge wasn't keeping temperature and the humidity was high. It walked through basic checks like door seals and vents, then pointed to a likely defrost failure and guided Deckerd through removing the freezer's back panel, where the evaporator coils were iced over. ChatGPT then explained how to test the heater, thermostat and sensor with a multimeter and estimated $20–$60 for DIY parts. The parts it first suggested weren't right for the model, so Deckerd confirmed the correct part numbers on an appliance parts site using the model and serial number, then ordered a $20 kit. After replacing the defrost heater, the fridge worked again, and Deckerd avoided a $300+ service call.
