First check

1 Prove inducer and the live code

Do not pull power — that clears the Amana AM9S96 active code. Write 3 flash. Is the inducer spinning on this call? Silent inducer is not a pressure switch. Trap, collector, and vent first — these 96%s drown a collector overnight.

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.

On the plates

  • Trap, collector, and vent first — these 96%s drown a collector overnight.
  • Inducer 120 VAC and spinning.
  • Hose dry and on the only collector tap.
  • If the PS closes and the IFC still 3-flashes, the IFC input is the fault.

Plates that use 3 flash

Same number, other makers

3 flash on Amana is not the same code on these plates.
