First check

1 Ohms at the igniter, then at the IFC

On Goodman GR9S96 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. Ohms at the igniter plug, then at the IFC.

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

The rest of the walkthrough is Diagnose.
