First check
1 Watch one full try — do not reset
Write the Goodman GMSS96 code. Watch inducer, HSI glow, valve click, flame, µA. The step that dies is the repair. Resetting only burns another try into a harder lockout. Watch a try: inducer, HSI, valve, flame.
Expect: W → No W2 path
The rest of the walkthrough is Diagnose.
On the plates
