Welcome to the
Dometic
A.E.S. refrigerator training program. In this program we will discuss the
features, operating sequences and diagnostic procedures for the
Dometic
refrigerators that are
equipped with the Automatic Energy Selector Control system; A.E.S. for short.
(2)
With this type of control system the customer
no longer has to manually switch the
refrigerator to the desired mode of operation.
All that is left for the customer to do is to turn
the refrigerator “ON” and to select the desired
temperature range by way of the thermostat
knob. The refrigerator will automatically select
between 120V AC,
12V
DC or LP gas to
operate the refrigerator.
(3)
The selection will be made electronically with
the highest priority going to the
12OV
AC
cooling mode; second priority going to the
12V
DC heating element, providing the motor
home’s ignition key is turned “ON” and the
vehicle is in motion. Last priority is LP gas
operation.
(4)
Since the introduction of the first A.E.S.
refrigerators in 1983 there have been three
distinct model series or “generations” available.
We will discuss each of the three model gener-
ations separately to illustrate the parts location
and operational differences between each
model series.
