Possible Causes

Loose fan wheel on motor shaft, Broken fan blade, Worn fan motor bearings, Loose compressor mounting bolts or rubber grommets

How to Fix / Troubleshooting

Safety: Unplug the unit before removing covers. Keep fingers away from fan blades.

Steps:

  • Identify noise source: Remove the front or rear panel and briefly run the unit (if safe) to locate whether the noise comes from the fan area or compressor area.
  • Fan inspection: With power off, check that the fan wheel is firmly attached to the motor shaft. Tighten the set screw if loose. Replace the Argo fan wheel if cracked or unbalanced.
  • Motor bearings: Spin the fan by hand. If it feels rough or wobbly, replace the Argo indoor fan motor.
  • Compressor mounts: Inspect the rubber grommets under the compressor. Replace any that are cracked or missing and tighten mounting bolts to reduce vibration.
  • Reassemble and test: After securing components, reassemble and run the unit to confirm noise reduction.
