Goodman codes

Goodman

2 flash

Lockout

IGC 2-flash — example

Example on most Carrier/Bryant packaged CES IGC stickers: pressure switch / draft did not make. Confirm the sticker in THIS heat section — revisions differ.

Walk 2 flash in Diagnose

2 plates — walk the one on the cabinet

First check

1 Prove inducer and the live code

Do not pull power — that clears the Goodman GMSS96 active code. Write 2 flash. Is the inducer spinning on this call? Silent inducer is not a pressure switch. Unplug the PS. Hose water holding residual draft.

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

  • Unplug the PS. Hose water holding residual draft.
  • Welded switch or IFC input shorted.
  • Type 2-flash / 2 flashes as the IGC shows it. Then walk inducer → hose → switch.
  • Inducer spinning. Roof hoses fill with water.
  • Do not leave the switch jumped.

Same number, other makers

2 flash on Goodman is not the same code on these plates.
