Cooling or refrigeration problem
This initial diagnostic sequence helps pinpoint the source of operational issues using safe, accessible checks.
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.
- For any issues encountered during this flow, especially those involving electrical components or cooling systems, immediate assistance from a qualified technician is required.
- If the diagnostic process points toward electrical faults or refrigeration issues, only a qualified technician should proceed with further testing.
