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.
