Cooling or refrigeration problem Review
This flow provides an alternative diagnostic path when the initial checks do not resolve the reported 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 troubleshooting requires accessing the main power distribution area, a qualified technician must perform all checks involving voltage or electrical supply.
- If the issue points toward the cooling system, a qualified technician must handle all refrigerant or electrical work.
- For any electrical troubleshooting, a qualified technician must inspect the terminal block and wiring.
- If the issue involves the compressor or refrigeration components, a qualified technician must take over immediately.
