No Power Diagnosis

This section guides you through systematically checking the power path, from the wall outlet all the way to the machine's internal power distribution, to pinpoint where the power loss is occurring.

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 at any point: Immediately unplug machine. Do not re-energize. Tag out and escalate to licensed technician.
  • Fuse blows more than once: Do not install a third fuse. Investigate for short circuit or component failure. Escalate to technician-advanced.
  • If you suspect an issue with the main power input or internal wiring, you must contact a qualified technician immediately.
  • If fuse blowing is suspected, do not replace it until a qualified technician has investigated the underlying cause of the fault.
