How to Fix / Troubleshooting

Safety first: Turn off power and gas. Allow moving parts to stop before touching.

  • Tighten hardware: Check all accessible screws and bolts on the Kripsol fan assembly, burner tray, and cabinet panels. Tighten as needed.
  • Inspect fan wheel: Look for debris stuck in the fan wheel or bent blades. Clean and straighten minor bends carefully.
  • Add anti-vibration pads: Ensure the heater is installed on a solid, level base. Add rubber pads under the feet if necessary.
  • Replace fan if needed: If vibration persists and the fan wheel is visibly wobbling, replace the Kripsol fan assembly.
