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.
