🚫 Dirty Air Filter (Most Common Cause): This is the most frequent culprit. A clogged filter severely restricts airflow, causing the indoor coil to get too cold. The AC then shuts down to prevent freezing and damage. You should check and clean the AC's air filters thoroughly. 🔌 Electrical Power Issues: Problems with the power supply are a key suspect. A tripped breaker, a blown fuse, or loose wiring can cause the unit to power off and on erratically. Please inspect your circuit breaker and any fuses to ensure everything is secure and functional. 🚧 Obstructions and Blockages: The system needs clear airflow to operate correctly. You should check both the indoor and outdoor units for any blockages. Ensure there are no furniture, curtains, or debris covering the intake and outlet vents on the indoor unit, and that the outdoor unit's fan and coil are clean and unobstructed.
