Machine Completely Dead - Diagnostic Flow
This systematic guide addresses a total loss of power response, starting with facility power verification and escalating to internal electrical checks.
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 or scorching detected at any point: Stop immediately. Unplug machine. Do not investigate further. Hand off to qualified technician.
- Exposed conductors on power cord: Unplug immediately. Do not operate. Tag machine out of service.
- If the machine remains unresponsive after verifying facility power, any investigation involving the main power input, fuse, or internal wiring must be performed by a qualified technician.
- If any exposed conductors or high-voltage components are visible, service must be immediately escalated to a qualified technician.
