DESCRIPTION OF OPERATING
MODES
LIMP MODE OF OPERATION
This control system contains a feature where it will con-
tinue to operate the cooling system in the event of a fail-
ure of a major operating component. Two different modes
of operation can occur in this category.
If for some reason the display module becomes non func-
tional, the refrigerator will continue to operate and the
temperature of the refrigerator will be maintained at the
MID position within normal temperature tolerances. The
power module will continually attempt to reestablish op-
eration of the display module.
The second limp mode of operation will execute when a
failure of the temperature sensing device or associated
electronic circuitry occurs. If this should occur, the re-
frigerator will run continuously.
The refrigerator will continue to operate in this mode in-
definitely or until a new sensor is installed and the sys-
tem is reset.
