Dead Machine Power Diagnosis
When the machine shows no signs of life, we must methodically check the power path from the facility source inward to the control board to pinpoint the source of the outage.
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.
- Repeated fuse failure
- Burning smell at any point
- Visible arc or spark
- Water near live electrical components
