Outcome
Jassy's homestead relies on a commercial glass-door cooler for garden harvest, eggs and bacon mid-cure, but it had sat broken for 8 months because a repair call would cost $600 or more. Jassy described the symptoms to Claude: it cooled for 24–48 hours, then cut out while the fan kept running, with no icing. Claude came back with six things to check, saying which were reasonable DIY jobs. It suggested cleaning the coils. After that, Jassy reported that the fan ran and they could hear it calling for the condenser but the condenser did nothing. Claude was then fairly confident it was a bad start relay or overload protector, about $15 each. Jassy replaced both themselves, the cooler cooled almost immediately and had held steady for a month. Parts were about $30 with shipping.

I have a commercial fridge (Coldtech J1GR-24L) that cools for about 24-48 hours and then kicks off. Fan continues to run but no cooling occurs. It doesn’t appear to ice up anywhere. Help me troubleshoot and pinpoint the problem with step by step instructions.

Optional stronger version
Our rewrite with extra checks. The poster didn't test it.
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: Work out why an appliance has stopped working, and whether I can fix it myself safely. What I can give you (ask for whatever's missing): - The appliance make and model: [MODEL] - Exactly what it does and doesn't do (sounds, lights, error codes, timing): [SYMPTOMS] - What I've already tried, and photos if useful: [DETAILS] 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: - Give me a short list of likely causes, cheapest and easiest to check first. - Mark each step as safe DIY or a job for a technician. - Ask what I observe after each check before moving on. - When we've narrowed it down, name the part and where to buy the right one for my model. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. - Remind me to unplug the appliance before opening any panel, and to call a professional for anything involving refrigerant. Output: A step-by-step checklist, then the likely fault, the part and how to replace it. You'll know it worked when: the appliance works again, or I know exactly what to ask the 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.

When the bottom section of their fridge warmed to about 11–14°C, the poster worked through a process of elimination with Grok, which pointed to the freezer fan and found the cheapest well-reviewed replacement (C$32.18 with taxes). The fan arrived the next day; the poster says it was indeed the problem and the fridge is working perfectly now.

- Find a fridge's uneven cooling came from dusty condenser coils with NotebookLMEvidence: Article or interviewBeginner-friendly
Anu Joy built a NotebookLM notebook for their refrigerator from the manual, the invoice, repair guides, YouTube videos and Reddit threads, then asked why the fridge section wasn't holding temperature evenly. It listed common causes such as blocked vents, shelf obstructions and worn door gaskets. After ruling those out, Joy found the condenser coils coated in dust, cleaned them, and watched a thermometer show the cooling stabilising within about half an hour.

- Get a dead AC condenser running again from photos with GrokRecreated promptEvidence: Described by poster
With their upstairs bedroom hitting 90°F, a poster asked Grok how to cool the house and found the outdoor condenser wasn't running. He says Grok walked him step by step through fuses, capacitors, contactors, multimeter use and Nest and furnace control-board wiring from his photos; after hours of near-misses he booked an HVAC visit, but Grok then spotted miswired Nest thermostat and control-board wires. After he fixed the wiring the AC ran, and he cancelled the appointment, estimating he saved $1,000+.
