No power or dead display Review
This flow addresses common operational faults by systematically checking various subsystems for anomalies.
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.
- If the diagnostic process indicates an issue within the power supply area, only a qualified technician should investigate the internal connections.
- Any investigation into the control system's electrical components requires the presence of a qualified technician.
- If the fault is suspected to be related to the refrigeration cycle, a qualified technician must handle the inspection.
