Cooling Performance Diagnostic
This evaluation assesses the refrigeration system's ability to maintain proper temperature through non-invasive checks of airflow and component operation.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Sealed-system issue suspected: Stop all external diagnostics. Mark as requiring manufacturer-or-licensed refrigeration technician. Do not tap, pierce, or open any refrigerant line.
- Compressor running with no condenser fan: Power off immediately to prevent compressor damage.
- Because this diagnostic involves refrigeration components and sealed systems, a qualified technician specializing in refrigeration must perform any deep investigation.
- If the compressor is running but the fan is not, immediately power down and call for a qualified technician.
