Cooling or refrigeration problem
This flow guides users through initial, non-invasive checks to narrow down potential operational 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 the issue persists after these steps, a qualified technician must be called to safely assess the internal components.
- For any electrical or refrigeration concerns encountered during this flow, only a qualified technician should proceed.
