Diagnostic & Repair Steps

Check Airflow and Coils
Inspect indoor/outdoor coils and air filters for dirt, blockage, or ice buildup. Poor airflow causes refrigerant pressure and temperature issues. 🔧 Flashlight

INSPECT ~10 min

Clean Filters and Coils
Clean or replace air filters. Clean coil fins with compressed air or low-pressure water. 🔧 Air compressor, fin comb ⚠️ Do not use high pressure water on fins

CLEAN ~20 min

Check Fan Operation
Verify indoor and outdoor fans spin freely and at correct speed. Faulty fans cause pressure and temperature protection to activate. 🔧 None

CHECK ~10 min

Check Refrigerant Pressure
Connect manifold gauge set to service ports. Check both high and low side pressures against manufacturer specification for current ambient temperature. 🔧 Manifold gauge set, refrigerant charts ⚠️ Only certified technicians should handle refrigerant
