Recertification Inspection Protocol

• Inspect the display for pixel clarity and brightness, replacing any dim or dead pixels.
• Test all buttons for responsiveness, resistance, and durability; replace any that don’t meet standards.
• Check the door seal and lock for airtightness, replacing any compromised components.
• Run diagnostics on PCB test points for voltage and current accuracy, replacing faulty components.
• Verify compressor output and airflow, ensuring all internal fans function properly.
• Cross-check internal temperature probe accuracy with a NIST-traceable probe, recalibrating if needed.
• Inspect wiring for frays or tears, replacing compromised sections as necessary.
• Test the start capacitor's capacitance and replace if it’s outside the specified range.
• Replace all internal filters and thoroughly clean condenser fins for efficient heat dissipation.
• Verify the alarm battery holds a full charge and replace if there is any degradation.
• Operate the unit for 72 hours to confirm stable temperatures and operational consistency.
• Perform a final cosmetic check, repairing or touching up surfaces as needed for a professional appearance.
