Lockout

Ignition

HSI / gas / rod.

Walk 14 / 34 in Diagnose

4 plates — walk the one on the cabinet

First check

1 Ohms at the igniter, then at the IFC

On Bryant 800S measure cold ohms at the igniter plug, then at the IFC connector. An open at the plug is the element or local harness. Open only at the IFC is the harness rub-through on the collector. Fix 31 draft before a fair 34 test.

Expect: Nitride cold ohms per THIS door sticker — do not use an 80% Norton chart.

The rest of the walkthrough is Diagnose.

On the plates

  • HSI, gas, rod, ground.
