This initial diagnostic sequence guides you through basic operational checks to narrow down potential service issues.
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.
- If any issue arises during this flow, immediately stop and contact a qualified technician, as further steps may involve live-voltage components.
- For any suspected electrical fault, a qualified technician must assess the situation before proceeding.
