Possible Causes

Loose indoor fan blower wheel, Foreign object in blower, Loose front panel or mounting plate, Worn indoor fan motor bearings

How to Fix / Troubleshooting

Safety first: Turn off power before opening the indoor unit. Do not insert fingers into the blower wheel.

Steps to check:

  • 1. Inspect front panel: Ensure the front cover is fully closed and latched. Tighten any visible screws.
  • 2. Remove foreign objects: Open the panel and filters. Look for plastic, paper, or other debris caught in the blower wheel and remove carefully.
  • 3. Check blower wheel play: Gently move the blower wheel side to side. Excessive play or wobble may indicate a loose set screw or worn bearings.
  • 4. Check mounting plate: Verify the indoor unit is firmly attached to the wall bracket and that the bracket is secure to the wall.

When to call a technician: If noise persists or the blower wheel is cracked/loose on the shaft, the blower assembly or fan motor may need replacement.
