Walk 10 in Diagnose

8 plates — walk the one on the cabinet

First check

1 Prove inducer and the live code

Do not pull power — that clears the Rheem R801S active code. Write 10. Is the inducer spinning on this call? Silent inducer is not a pressure switch. This is Category I metal vent. There is no 96% collector or PVC trap to prime.

Expect: 120 VAC at the inducer on a heat call. Wheel turning.

If fail: 120 VAC missing → IFC / door switch / incoming power. Voltage + dead motor → inducer.

If pass: Inducer running + this code → trap, hose, switch, vent (step 2).

The rest of the walkthrough is Diagnose.

  • Read the code that led here (11 / 45 / 57). Do not just wait the hour.
  • Watch one full try after a controlled reset.
  • Read the code under it (11, 45, 46, 57). Do not just wait the hour.
  • Read the code that led here (11 / 45 / 57).
  • Read 11 / 45 / 57 underneath.
