Diagnostic Flow: No Power / Blank Display
This flow guides you through checking the basic power supply from the wall outlet to the machine's internal components when the unit shows no signs of life.
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.
- Burning smell detected
- Water intrusion visible
- If the issue persists after basic checks, immediate escalation to a qualified technician is required for diagnosis of live voltage circuits or the main control board.
