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.

  • For any issues encountered during this diagnostic process, especially those involving electrical components or internal mechanisms, contact a qualified technician immediately.
  • If the issue points toward the control board or power supply, only a qualified technician should proceed with inspection.
  • If the issue involves the refrigeration system, a qualified technician must assess the situation due to potential high-voltage or refrigerant hazards.
