refrigerator

Documented refrigeration purpose

Record manufacturer and model identification, the intended storage application and evidence that the enclosure provides refrigerated storage.

1. What label, manual or other evidence identifies this appliance and its intended storage application? provenance
2. Does the appliance provide a refrigerated compartment, or is it a passive cooler, freezer-only appliance or cold-room installation? boundary

Compartment roles and control coupling

Record each compartment's intended role, convertible modes and any documented sharing of controls or cooling paths.

1. Which compartments are intended for refrigerated, frozen or convertible storage? definition
2. Which settings or operating modes affect multiple compartments, and what documentation establishes that relationship? provenance

Observed versus requested temperature

Record control settings separately from measured temperatures, identifying whether measurements represent air, a buffered probe or contents.

1. What temperature was measured, when, where and with what sensor or measurement method? measurement
2. Does the displayed value represent a setpoint, a current measurement or another manufacturer-defined indicator? definition
3. What documented requirement is being used to judge this compartment's temperature? provenance

Excursions and cooling recovery

Record temperature excursions and recovery after loading, door openings, power interruptions or defrost, without inferring unobserved history.

1. What temperature range and excursion duration are supported by observations, and where are monitoring gaps? measurement
2. Which loading, door, power or defrost events coincide with the observed temperature change? provenance
3. What documented recovery criterion determines whether to continue monitoring or escalate a possible cooling failure? action

Required supplies and availability

Record the documented cooling mechanism, required energy sources and whether each required connection is available and appropriate.

1. Which refrigeration mechanism and energy requirements are stated on the appliance or in its documentation? provenance
2. Are the required supplies currently available, and what observation supports that assessment? measurement

Heat rejection and installation fit

Record ambient conditions, required clearances, ventilation obstructions and any documented positioning or mounting requirements.

1. How do measured ambient temperature and available clearances compare with this model's documented limits? measurement
2. Are required heat-rejection paths obstructed or exposed to installation conditions the manufacturer excludes? boundary
3. Which authorised placement or ventilation correction can be made, and what performance observation should follow? action

Closure, frost and drainage condition

Record door closure, gasket condition, frost accumulation, condensation and drainage observations without treating any single symptom as a confirmed diagnosis.

1. Do all doors and drawers close as intended, and are their seals damaged, dirty or obstructed? measurement
2. Where are frost, condensation or water accumulating, and under what operating conditions? measurement
3. Which cleaning or defrost procedure is documented for this appliance and permitted for the acting agent? action

Load compatibility and airflow

Record proposed contents' externally supplied storage requirements, available space, shelf limits and placement restrictions.

1. Which compartment can meet the proposed contents' documented storage requirements, and which requirements remain unknown? boundary
2. Does the proposed placement preserve required airflow, door closure and documented shelf or drawer load limits? measurement
3. Should the agent accept, rearrange or defer the proposed load based on available capacity and current cooling evidence? action

Supported control and alarm response

Record available modes, active settings, alarm indications and documented meanings, including any mode that changes normal storage capability.

1. Which mode is active, and what does the manual say it does to each compartment's cooling behaviour? definition
2. What alarm or fault indication is present, and which appliance-specific source explains it? provenance
3. Which authorised control action is appropriate, and what observation will verify its effect? action

Service boundaries and disposition

Record unresolved symptoms, maintenance history, refrigerant identification where applicable and documented requirements for service, transport and disposal.

1. Which maintenance or repair actions are evidenced, and which cooling, leakage or mechanical symptoms remain unresolved? provenance
2. Which proposed tasks are user-serviceable according to the documentation, and which require a qualified service provider? boundary
3. What appliance-specific instructions and applicable local requirements govern repair, relocation or retirement? action
