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 from motor or harness: stop-immediately
  • Motor diagnostics involve electrical circuits, and any testing of the motor harness or drive signals must be performed by a qualified technician.
  • If the motor remains unresponsive after checking the signal, a qualified technician should assess the motor unit itself.
