release
MODE
to displa

operation.
DC electric should not be used to initially cool the refrigerator
. Onl
y
use DC when the other
modes are unavailable
(
for example; while in transit
)
.
Durin
g
operation in AUTO mode, if a hi
g
her priorit
y
ener
gy
source becomes available, the controls stop usin
g
the current ener
gy
source and switch to the hi
g
her priorit
y
ener
gy
source. If AC becomes available while the
refri
g
erator is in AUTO LP GAS mode, the refri
g
erator switches to AUTO AC operation.
If an operatin
g
mode is not functional, its LED flashes and the refri
g
erator tries to operate in a lower ener
gy
priorit
y
source. If a lower ener
gy
priorit
y
source is not available, the LED continues to flash, and the refri
g
erator stops operatin
g
until the ener
gy
source is corrected. See
Diagnostics
for corrective actions.
