Machine Completely Dead — No Power Diagnostics

This diagnostic checks the entire power path to determine if the machine is receiving any power from the source outlet.

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 signs of arcing detected: stop-immediately
  • Water intrusion near electrical components: stop-immediately
  • If power cannot be confirmed at the main service point, this requires immediate attention from a qualified technician.
  • Do not proceed with internal checks until a qualified technician has verified the incoming power supply integrity.

Start outside the machine at the outlet and cord, then identify the power entry area before any protected-compartment inspection.

  • Receives main AC power from the wall outlet and distributes it through the machine's electrical system.
  • Power cord
  • Terminal block or power entry
  • Main fuse or circuit breaker

Do not open energized or protected electrical areas unless a qualified technician or licensed electrician is handling the work.
