How to Fix / Troubleshooting

Safety: Turn off power and gas before removing inducer assembly. Inducer is part of the venting safety system.

Steps to check:

  • Inspect inducer housing: Remove the burner door and visually inspect the inducer for cracks, water leaks, or loose mounting.
  • Tighten screws: Gently tighten inducer mounting screws if loose.
  • Listen to motor: If the inducer squeals or grinds when running, the motor bearings are likely failing and the inducer assembly should be replaced.
  • Check condensate drain: On condensing models, ensure the condensate line from the inducer is not blocked, which can cause water buildup and noise.
