Walk 6 flash in Diagnose

4 plates — walk the one on the cabinet

First check

1 Treat this as flame outside the exchanger

Do not reset the Goodman GMS80 rollout and walk away. Write the code, kill the call, and look for flame at the burners, crossover, and vestibule before you do anything else.

Expect: No flame outside the exchanger. Burners seated. Crossover lit.

If pass: Still inspect secondary / flue / condensate before you reset.

The rest of the walkthrough is Diagnose.

On the plates

  • Exchanger, burners, crossover, flue, secondary / condensate.
  • Reset only after the cause is fixed.
  • Exchanger, burners, flue. Reset only after cause.
  • Watch one try: inducer → PS → glow → valve → flame. The dead step is the repair.
  • HSI ohms, 24 VAC at the valve during trial, inlet gas on the roof.
