Gondenser Fan Noise
Symptom: Loud airflow noise coming from the
condenser fan compartment.
Problem: The plenum is bent out of position due to
the screw tab being tightened at an angle.
Solution: Release the tension off the plenum by
loosening the screw tab. Straighten the plenum to
the proper position around the fan blade. Tighten
the screw so the tab is straight.
