Cabinet temperature too warm
Guided diagnosis when the Crane 962 cabinet is not cooling properly, potentially triggering the health shutoff control.
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.
- Health shutoff trips: Stop and investigate immediately. Do not reset without identifying root cause. Product safety may be compromised.
- Compressor seized or shorted: Lock out machine. Requires manufacturer-or-licensed sealed-system service.
- Refrigerant leak suspected: Evacuate area if large leak. Stop all work. Contact licensed refrigeration technician.
