Cooling System Diagnostics

This systematic check verifies that the unit is maintaining the correct product temperature by examining airflow, seals, and the performance of the cooling components.

Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.

  • Compressor running but no cooling effect observed: Possible sealed-system issue. Stop non-invasive checks. Escalate to manufacturer-or-licensed.
  • Oil visible around compressor or refrigerant lines: Refrigerant leak suspected. Stop work. Escalate to manufacturer-or-licensed.
  • If the compressor is running but no cooling effect is observed, this suggests a sealed-system issue requiring a qualified technician.
  • If oil is visible around the compressor or refrigerant lines, this indicates a refrigerant leak and requires a qualified technician.
