Unit runs but airflow from vents is very weak.

Safety: Unplug the unit before cleaning or inspecting internal parts.

Steps:

• Clean filter: Remove and clean the air filter.
• Check for ice: Inspect the evaporator coil for ice buildup. If present, turn the unit off and allow all ice to melt. Then restart with a higher fan speed and ensure vents are not blocked.
• Inspect vents: Make sure furniture, curtains, or other objects are not blocking the intake or discharge.
• Fan motor: If airflow remains weak with a clean filter and no ice, the indoor fan motor may be failing and should be tested and replaced if necessary.
