Click steps to track your progress.
Turn off the air conditioner immediately using the remote control to prevent further damage.
Turn off the main power supply breaker for the indoor unit for safety before any visual inspection.
Visually inspect the outdoor unit's fan area for any large debris or obstructions that might be blocking the fan blades.
