Lockout

Ignition lockout

Hardened 34. Auto-reset ~3 h.

7 plates — walk the one on the cabinet

First check

1 Watch one full try — do not reset

Write the Carrier 58SP0 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. HSI, gas, rod, ground. Do not sit on resets.

Expect: W → No PVC → 58CTA cousin

The rest of the walkthrough is Diagnose.

On the plates

HSI, gas, flame sensor, ground. Do not sit on resets.
