01 /Report each compartment separately
Record the temperature shown for the refrigerator and, if present, the freezer. State whether both areas changed at the same time or only one seems affected. Sub-Zero uses different zone arrangements across its families; a working freezer does not by itself establish that the fresh-food area is operating correctly. Avoid treating a display reading as a diagnosis of a particular component.
02 /Distinguish a column from a combination appliance
The model-number key identifies different configurations, including all-refrigerator and refrigerator/freezer units. A column next to a freezer can look like one large appliance. Give the model for the cabinet with the symptom and describe any internal or external dispenser separately. If the label cannot be read safely, send the visible layout and retain any purchase or prior-service paperwork.
03 /Plan access around a built-in installation
Mention custom panels, nearby islands, restricted door opening or flooring that affects access. Leave the unit installed; do not remove trim or attempt to slide it out before the team reviews the setup. Photograph water where it first appears and note whether it is associated with dispensing, rather than assuming a leak and a cooling problem have the same cause.
04 /Request service from the Glendale base
Check the property ZIP against the listed California coverage, then provide the full appliance model, the symptom and any access restrictions. A matching ZIP does not reserve a visit or guarantee acceptance of every address. The team confirms equipment scope and appointment availability. You receive a written repair estimate before approving work; parts and any follow-up visit depend on the assessment.
