  • Possible causes:
    • Loose or damaged power connections

  • DIY Check:
    • Ensure the unit is properly plugged in
    • Test the outlet with another appliance
    • Check for tripped circuit breakers
    • Inspect the power cord for damage

2. Temperature Control Problems

  • Symptoms: Inconsistent cooling, temperature display errors, food freezing or spoiling
  • Possible causes:
    • Failed temperature sensors
    • Corrupted control board programming
    • Damaged temperature probes
  • DIY Check:
    • Verify temperature settings
    • Clean temperature sensors

  3. Visual Inspection: Look for signs of water damage, burnt components, or loose connections.
  4. Connection Check: Ensure all visible wires and connectors are properly seated.
