Cooling or refrigeration problem Review
This secondary diagnostic path guides you through further troubleshooting steps if the initial checks do not resolve the reported malfunction.
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 troubleshooting requires accessing the main electrical supply or internal wiring, a qualified technician must perform the inspection.
- If the diagnostic path leads to the cooling system, only a qualified technician should assess the high-pressure gas or electrical components.
- Any procedure involving the compressor or high-voltage areas must be handled exclusively by a qualified technician.
