H2 code appears; system may limit operation due to high temperature conditions.

Safety first: Turn off power at the outdoor disconnect before cleaning or servicing.

• Step 1 – Improve airflow: Clear vegetation and debris around the condenser. Maintain proper clearance.
• Step 2 – Clean coil: Rinse the condenser coil thoroughly with a garden hose from inside out.
• Step 3 – Check fan: Confirm the condenser fan runs at full speed and is not noisy or wobbling. Replace if weak or failing.
• Step 4 – Shade and ventilation: If possible, provide shade without blocking airflow to reduce operating temperature.
• Step 5 – Professional evaluation: If H2 persists, a technician should verify refrigerant charge and system pressures.
