Furnace displays E9; inducer may not start

Safety: Disconnect power before working on the inducer assembly.

• 1. Listen for inducer: When there is a call for heat, the inducer should start first. If it hums or is silent, proceed with checks.
• 2. Inspect wiring: Remove the burner door and locate the inducer motor harness. Ensure the plug is fully seated and wires are not burnt or broken.
• 3. Check for obstruction: With power off, spin the inducer fan wheel by hand through the opening if accessible. It should turn freely without grinding. If it is stuck, debris or failed bearings are likely.
• 4. Capacitor (if equipped): Some inducer motors use a run capacitor. Inspect for bulging or leaking. Replace with the same microfarad rating if defective.
• 5. Replacement: If the inducer does not start with proper voltage present (requires meter), the inducer assembly must be replaced with a Frigidaire-compatible inducer kit. This is typically a professional repair.
