Possible Causes

Pellet dust compaction in auger tube, Foreign object in auger, Dry auger bearings, Misaligned auger motor

How to Fix / Troubleshooting

Safety first: Turn OFF and unplug the grill. Allow it to cool before working on the auger.

Steps:

  • Empty hopper: Remove pellets to expose the auger intake.
  • Remove auger and motor: Access from the service panel, unbolt the motor, and slide out the auger.
  • Clean and inspect: Remove compacted dust and any foreign objects. Check the auger shaft for bends and the tube for scoring.
  • Lubricate bearings: If your Napoleon model uses serviceable bearings, apply a small amount of high-temperature food-safe lubricant to the bearing surfaces (never to the pellet path).
  • Reassemble: Reinstall the auger and motor, ensuring proper alignment and quiet operation.
