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.

  • Due to the involvement of live-voltage components and sealed-system procedures, this issue requires immediate attention from a qualified technician.
  • The power relay check involves live-voltage components, so only a qualified technician should proceed with this step.
  • Any work involving the heating circuit or electrical connections must be performed by a qualified technician.
