Refrigeration — Airflow Restricted
This addresses situations where the cooling unit is running, but the product temperature is not dropping sufficiently, pointing toward airflow blockages or system inefficiencies.
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.
- Evaporator ices over again within days of manual defrost: Sealed-system or defrost control issue suspected. Escalate to manufacturer-or-licensed technician.
- Compressor runs continuously without cooling: Possible refrigerant loss or compressor failure. Sealed-system work required. Escalate.
- Because this involves sealed-system components, any deep investigation into the cooling cycle or refrigerant levels must be performed by a qualified technician.
- If the compressor runs continuously without achieving proper cooling, this requires specialized service from a qualified technician.

Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start at the affected product shelf or selection row; compare the tray, coil, and product path with a nearby working selection.
- Maintains cold product temperature through forced-air cooling.
- Compressor
- Condenser coil and fan
- Evaporator coil and fan
Do not open sealed-system or compressor areas unless a qualified refrigeration technician is handling the work.
