First check
1 Confirm this is not a fault
On the Goodman GMSS96 this readout (Steady on) is run status, not a lockout. Write what the display actually shows and whether W/Y/G is present at the IFC.
Expect: Idle / Ht / CF / stage+CFM words change when you apply and remove the call.
If fail: If the word never changes on a real call, the call is not reaching this IFC.
If pass: The board is alive. Diagnose the comfort complaint, not this code.
The rest of the walkthrough is Diagnose.
On the plates
- If the house is cold, the call is not reaching W. Check R to W at the IFC, not just at the stat.
