Loud rattling or vibrating noise from Soleus Air AC during operation.

Safety: Unplug the unit before tightening screws or accessing internal parts.

• Check installation: Ensure window units are properly supported and level side-to-side and slightly tilted outward. Portable units should sit on a flat, solid surface.
• Tighten hardware: Inspect the outer cabinet, front grille, and internal brackets. Tighten any loose screws or clips.
• Inspect blower and fan: Remove the front cover and observe the indoor blower wheel and outdoor fan blade. Look for wobbling, cracks, or contact with the housing. Adjust or replace if damaged.
• Add padding: For minor cabinet vibration, add thin foam strips between the unit and window frame or between panels to dampen noise.
