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.

  • Because this flow involves advanced diagnostics, any electrical or refrigeration concerns must be addressed by a qualified technician.
  • If the advanced checks suggest internal electrical faults, only a qualified technician should investigate the power systems.
  • If the issue requires working within the cooling system, a qualified technician must perform the necessary service.
