How to Fix / Troubleshooting
Safety First: Unplug before touching moving parts.
Steps:
- Isolate source: Remove panels and listen carefully to determine if the noise comes from the fan area, pump, or compressor.
- Inspect fans: Remove debris from blades and ensure they are not rubbing on shrouds. Replace noisy fan motors with OEM Arktic parts.
- Check circulation pump: If the noise coincides with water circulation, the pump impeller may be worn or obstructed. Remove and inspect the pump; clean or replace as needed.
- Tighten hardware: Tighten any loose screws or brackets that may vibrate.
