Products Not Cold - Refrigeration Performance Diagnostic
Non-invasive assessment of refrigeration performance focusing on airflow, cleanliness, door seal, and compressor run state before any sealed-system consideration.
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.
- Oil leak detected at compressor or any refrigerant line: Stop. This indicates a sealed system leak. Requires manufacturer-or-licensed service.
- Compressor attempts to start repeatedly with clicking sound: Possible start device failure or compressor seizure. Hand off to technician-advanced.
- Frost buildup only on part of evaporator coil: May indicate restricted refrigerant flow or low charge. Sealed system evaluation needed.

- 1
Check product temperature
operator-intermediatelowPlace a thermometer in the center of the product area. After allowing time for stabilization, record the temperature.
ThermometerExpected: Temperature reading within expected range for beverage products.
Evidence to note: meter-reading

Inspect condenser coil cleanliness
operator-intermediatehighAccess the condenser coil area, typically near the compressor. Visually check for dust buildup or debris. If dirty, carefully clean using a coil brush.
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.
Flashlight or Work LightCondenser Coil BrushStop conditions- Condenser fan blade accessible - keep hands clear during operation
Expected: Condenser coil is clean and air can pass through freely.

Check door seal integrity
operator-intermediatelowClose the door on a sheet of paper at several points around the perimeter. The paper should be gripped firmly. Test multiple locations.
Expected: Paper is held snugly at all test points around the door.
Evidence to note: note

Observe compressor run state
operator-intermediatehighListen for compressor operation. Feel for vibration at the compressor housing. Note whether the compressor is running, trying to start, or silent.
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.
Flashlight or Work LightStop conditions- Burning smell from compressor area - disconnect power immediately
- Oil leak visible around compressor - sealed system issue, hand off to manufacturer-or-licensed
- Compressor extremely hot with burning odor - disconnect power
Expected: Compressor runs steadily with consistent vibration and humming sound.
