This advanced flow requires deeper investigation into system components, which should only be attempted by trained personnel.
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 suspected electrical or refrigeration issue requires immediate attention from a qualified technician.
- If you suspect internal system failures, do not proceed; contact a qualified technician who can safely evaluate the system.
