Purpose: To help identify and possibly resolve common issues with equipment before dispatching a service technician
Equipment Identification
  • Take Photo of Equipment
  • Take Photo of Equipment nomenclature plate
  • Take Photo of Equipment Display Panel.
  • Take Photo of Equip ID Tag Affixed to Equipment
Power Supply Verification
  • Check Power Connection: Ensure the freezer is plugged in securely.
  • Inspect Circuit Breaker: Verify that the circuit breaker hasn't tripped.
  • Test Outlet: Plug another device into the outlet to confirm it's supplying power
Temperature Assessment
  • Display Reading: Is the temperature display functioning correctly?
  • Setpoint Confirmation: Ensure the set temperature matches your requirements (typically between -70°C and -80°C).
  • Recovery Time: If the freezer was recently loaded, allow adequate time for temperature stabilization s
Frost and Ice Buildup
  • Door Seals: Inspect for ice accumulation around door gaskets, which can prevent proper sealing.
  • Interior Frost: Check for excessive frost inside the chamber, which may indicate the need for defrosting.
  • Vacuum Relief Port: Ensure the port is free from ice to maintain proper pressure balance.
Condenser and Ventilation
  • Condenser Coils: Clean any dust or debris from the coils to ensure efficient heat exchange.
  • Airflow Clearance: Maintain at least 8 inches of clearance around the unit for proper ventilation.
  • Ambient Temperature: Ensure the room temperature is within the recommended range (15°C to 32°C)
Door Functionality
  • Seal Integrity: Check that door gaskets are intact and free from tears.
  • Latch Operation: Confirm that the door latches securely without resistance.
  • Door Openings: Minimize the frequency and duration of door openings to maintain internal temperature.
Alarm Indicators
  • Alarm Status: Note any active alarms or error codes displayed.
  • Alarm Response: Refer to the user manual for guidance on specific alarms.
  • Mute Function: If necessary, use the mute function to silence alarms temporarily while addressing
Sample Storage Practices
  • Sample Temperature: Avoid placing warm samples directly into the freezer; pre-cool them if possible.
  • Organization: Use racks or boxes to organize samples, facilitating quick access and reducing door open time.
  • Inventory Management: Regularly review and remove outdated or unnecessary samples to optimize
Maintenance Records
  • Service History: Keep a log of maintenance activities and any issues encountered.
  • Scheduled Maintenance: Adhere to the manufacturer's recommended maintenance schedule, including defrosting and component checks.
  • Professional Servicing: Arrange for annual servicing by qualified technicians to ensure optimal
