Koldfront air conditioner runs but airflow from the front grille is very weak.

Safety first: Unplug the unit before cleaning or accessing the blower.

Steps:

• 1. Clean filter: Remove and wash the filter; reinstall when dry.
• 2. Check louvers: Make sure the air discharge louvers are open and not blocked by curtains or furniture.
• 3. Inspect evaporator coil: Remove the front cover and check for heavy dust buildup on the coil. Clean with a soft brush or coil cleaner.
• 4. Clean blower wheel: If accessible, clean dust and debris from the blower wheel blades.
• 5. Motor performance: If the blower motor runs slowly or intermittently, it may be failing and should be replaced.
