First check
1 Prove inducer and the live code
Do not pull power — that clears the Bryant 581J active code. Write 2-flash. Is the inducer spinning on this call? Silent inducer is not a pressure switch. Type 2-flash / 2 flashes as the IGC shows it. Then walk inducer → hose → switch.
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
- Type 2-flash / 2 flashes as the IGC shows it. Then walk inducer → hose → switch.
