Lockout

Failed ignition

Trial without prove.

8 plates — walk the one on the cabinet

First check

1 Watch one full try — do not reset

Write the Rheem R801S 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, 24 VAC at the valve.

Expect: W → Limits

The rest of the walkthrough is Diagnose.

On the plates

HSI glow and 120 VAC during warm-up.
Gas cock, 24 VAC at the valve, manifold vs plate.
Rod, ground, crossover.
HSI, gas, rod, 24 VAC at the valve.
Same prove logic as TA — the motor and the 45/46 card are what changed.
