AI Master Tech · on site, at the machine
46 years of troubleshooting, on every service call
Stuck on a tough call? Enter the model, the symptom and any error code. ThermalForce HQ triages the most common problems for that exact machine, walks you through starting its diagnostic mode, then guides you test by test until you find the fault — with the schematic, the part and the supplier one tap away.
AI triage: the most common problems
Enter the model, the symptom and any error code (type it or say it). Get the top probable causes for that exact machine ranked High / Medium / Low, what the fault code means for that brand, and the root cause explained.
Start diagnostic mode on that machine
Step-by-step instructions to enter service or test mode on the model in front of you — the exact buttons and sequence — and how to exit when you're done.
Troubleshoot step by step
An ordered test sequence, cheapest and safest checks first, with expected ohms and voltages. Tap Pass or Fail on each test and save the results to the job. Safety warnings come first — power, capacitors, gas and refrigerant.
Schematics & wiring diagrams
Open the schematic, wiring diagram and parts list for the model right on the job. Add your own library of diagrams and OEM part numbers for your team.
Get the part
See if it's on your truck or in the warehouse. If not, the parts suppliers are already set up — one tap searches the model, and the part goes on the ticket.
Tap to talk — hands-free on the job
Hands full or gloves on? Tap the mic and say it. Symptoms, error codes (“F twenty-one” becomes F21), model numbers, your diagnosis, work completed and photo notes fill in by voice — in the diagnostics and across the whole job ticket.
Parts suppliers already set up — search the model in one tap:
- Marcone
- Encompass
- Repair Clinic
- Parts Dr
- Johnstone Supply
- Ferguson
- Bluon
- Parts Town
- WebstaurantStore
