The ARFG18PVLHD features an upper refrigerator compartment with a small window and independent manual defrost freezer below. Both sections include adjustable plastic-coated wire shelves that can be positioned at 1/2 inch increments to accommodate virtually any sized item. This unit includes LED internal lighting with an on/off rocker switch. The ARFG18PVLHD features a dual microprocessor temperature controller (refrigerator range: +2 to +8ºC; freezer range: -30 to -10ºC). The buffered temperature probes are encased in glycol-filled bottles to better simulate temperature of the stored product, with an additional sensor that reads air temperature to ensure superior temperature control. The current and min/max temperature display is viewable in Celsius or Fahrenheit to the nearest tenth of a degree. The audible and visual temperature alarms sound if the interiors go out of range. Additional alarms include a power failure alert, door open alarm, and sensor failure alert system.
