Operating Controls - Norcold 9182 Service Manual & Parts List

A 12 volt DC supply is required to maintain refrigerator's operating control functions. The refrigerator receives its DC power
from the vehicle's 12 volt system; either an auxiliary battery, a converter, or the engine battery. The 12 VDC system not only supplies
power to the refrigerator, but to other DC components in the vehicle.
The operating controls consist of two printed circuit board assemblies. The Control Board, located at the rear of the
refrigerator, contains the circuitry to operate the refrigerator. The Front Display Panel (located between the two doors) contains
the display area, the push-button switches, and a magnetically actuated door sensor.
