Power Supply

Furnishes the selected
source with the selected voltage to
operate the refrigerator, provided
the voltage inputs are correct (See
Figure 11.9). It supplies:
1. 12 volts DC to the HIGH HUMID-
ITY circuit (2-door models only)
2. 12 volts DC to the Eyebrow board
3. 12 volts DC to the Ignition
Module when GAS is selected
or when AUTO is selected and
120 volts AC is not present.
4. 12 volts DC to the DC heater
when DC is selected (3-Way
models only).
5. 120 volts AC to the AC heater
when AUTO is selected and
120 volts AC is present.

Cable

Connects the Power Supply and
Eyebrow board together. See Fig-
ure 11.10

Eyebrow Board

Selects the modes of operation.
When set to AUTO it will select AC
as long as AC is supplied. If AC is
lost for some reason it will auto-
matically select GAS. It also dis-
plays the mode of operation, de-
termines the operating tempera-
ture and indicates when a trial for
ignition has failed. On 3-Way mod-
els when DC is selected it will over-
ride the automatic mode.
