Frequently asked questions

Should I replace a part based only on an error code?

No. A code identifies a detected condition, not necessarily the failed component. Rule out safe, inexpensive causes and confirm the exact model.

Why ask what I already tried?

The best next action changes when earlier checks fail. The engine removes repeated actions and applies prerequisite rules before ranking what remains.

Are success rates verified?

Every rate shows its denominator. Photo, receipt, invoice, technician and follow-up verification remain separate signals; none converts a small sample into high confidence.
