Cooling or refrigeration problem
This initial diagnostic sequence guides users through basic, safe checks to narrow down the potential source of the operational issue.
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, or if any diagnostic step requires accessing internal components, a qualified technician must be called to safely assess the situation.
- For any electrical or refrigeration concerns encountered during diagnostics, only a qualified technician should proceed.
