Drive distance, not straight-line radius. Have these ready - The full model number and serial number from the plate. On full-size cabinets it is inside the fresh-food compartment on the upper left wall; on undercounter units it is behind the base grille. - Both compartment temperatures, read with a thermometer rather than from the display, against the 38°F and 0°F setpoints. - Any code shown on the display, written down exactly. Leave it on the unit — do not clear it before the visit. - When the condenser was last cleaned, and whether the grille is at the top or the bottom of the cabinet. Before you book ## Two answers that save you the call. If the fresh-food compartment is under 48°F and the condenser has not been cleaned in a year, clean it first and give the cabinet 24 hours. A good proportion of calls end there and it costs you nothing. If it is above 48°F against a 38°F setpoint, the manufacturer's own guidance is that a cleaning is unlikely to recover it. That is a service call, and waiting a week only adds a week of food loss. We do not offer after-hours or emergency service, and we would rather say so here than have you find out at 9pm.
