Wrenchable

Free for Claude · ChatGPT · Grok

RV Tech Assistant

Ask your own AI about an RV fridge code, a furnace that won't light or a water heater that keeps locking out. It answers from the actual service manuals, tells you which manual it used, and can price the repair as a printable estimate.

What it can do

Troubleshoot from the manuals

Searches the text of 10,000+ RV appliance and system manuals: refrigerators, A/C, furnaces, water heaters, converters, inverters, pumps, slides, levelers and generators. Fault-code tables, specs, wiring and procedures, each with the manual it came from.

search_manual_text

Find the right manual

Finds service manuals, parts lists, wiring diagrams and install guides by brand, appliance or exact model number, with a link to open the document.

search_manuals

Price the repair

Adds up labor, parts, materials, fees and tax from the numbers you give it, and makes a printable PDF estimate. It never guesses a rate or a tax.

Try asking

  • "My Norcold N8X is flashing no FL. What does that mean and what do I check?"
  • "Find the service manual for a Suburban SW6DE water heater."
  • "Aqua-Hot 450D showing an E3 error, what's the troubleshooting sequence?"
  • "Dometic A/C fan runs but the compressor won't start on generator."
  • "Make an estimate: replace the water pump, 1.5 hours at $150, pump is $125, 7% tax on parts."

Good to know

  • Sources, not guesses. Answers come from manufacturer manuals and name the manual. If the library doesn't cover your exact model or code, your AI is told to say so.
  • Codes differ by model. The same code can mean different things on different boards. Give the exact model number.
  • Safety. Propane, 120V and sealed refrigeration systems can hurt you. If you're not trained for it, call a qualified RV technician.
  • Privacy. We keep the search text and result counts to improve the library, never your name or conversation. Details in the privacy policy.
  • Read-only. The assistant only looks things up and does math. It can't change anything anywhere.
