No Power Diagnostic Flow

This flow guides you through checking the power path from the wall outlet right up to the unit's internal electronics to determine if the unit is receiving power at all.

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: Stop. Escalate to senior technician. Do not re-apply power.
  • Burning smell detected at any point: Immediately unplug. Do not probe further. Escalate.
  • If you suspect an issue with the main power input or internal wiring, you must contact a qualified technician immediately.
  • If the fuse check indicates a problem, do not re-apply power until a qualified technician has assessed the circuit for shorts.
