This advanced flow addresses complex system interactions requiring a higher level of technical expertise.
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 work concerning the high-voltage components or the refrigeration cycle must be handled exclusively by a qualified technician.
- If the issue points toward the main electrical supply or internal terminal block, a qualified technician must perform the assessment and repair.
