Troubleshooting a ductless mini-split system that has stopped producing chilled air requires checking airflow, power supplies, and operational settings. First, inspect the handheld remote control to ensure the system is switched explicitly to the "Cool" mode with a setpoint lower than current room temperature. Second, remove and clean the indoor unit's washable mesh air filters, as heavy dust buildup chokes airflow and freezes coils. Third, check the indoor display panel for blinking error codes. Fourth, inspect the outdoor condenser unit to ensure it has electrical power and is not blocked by debris. You can troubleshoot temperatures with a digital thermometer. You can verify that your troubleshooting is successful when clearing filter clogs, resetting power, or fixing airflow restrictions restores powerful chilled air output to your living space.
