Error will go away if the
control cycles off the
compressor or if the
power is shut off. If error
is on a cold pan it could
be related to a high
ambient temperature or
not shutting the rail off
nightly.
All alarms sound for approximately 10 seconds and then

then remain silent. The alarm code will still be present on the
display until the fault clears.

R290 Power Switch
All freezers and refrigerators are equipped with a power
disconnect switch located behind the louvered end panel.
Switch must be in the on position for the unit to operate. If
the switch is turned off, then returned to the on position, the
unit will enter a defrost cycle and the display will read dEF.
R290 Energy Switch
Refrigerators and freezers are equipped with an energy
saver switch for service use. It is located in the electrical
box behind the front shroud. It controls the length of time
that heat is applied to the door perimeter. If excessive
condensation is observed on the door opening, switch to the
off position with the help of an authorized service agent. The
off position will increase the length of time the door heater
is on.
Refrigerator operation - Energy Switch is “ON”, signaling
Energy Mode active, thus using the least energy. Unit ships
from factory in this mode where heaters are deactivated. If
the Energy Switch is turned “OFF”, the heaters will cycle with
the compressor, using more energy.
Freezer operation - Energy Switch is “ON”, signaling Energy
Mode active, thus using the least energy. Unit ships from
factory in this mode where heaters will cycle with the
compressor. If the Energy Switch is turned “OFF” by Service
in the field, the heaters will be always energized, using more
energy.
R290 Temperature Alarm
The alarm will sound and flash “HI” or “LO” 90 minutes
after the unit has reached its alarm temperature point or
after any power interruption if the temperature is above or
below the alarm set points. Refrigerators are factory set at
mid-range to maintain about 38°F (3°C) box temperature.
The high refrigerator temperature point is 50°F (10°C). The
low refrigerator temperature point is 25°F (-4°C). Freezers
are factory set at mid-range to maintain about -2°F (-19°C)
box temperature. The high freezer temperature point is 20°F
(-7°C). Freezers do not have a low temperature point.
R290 EVAPORATOR FAN OPERATION
Depending on the units requirements, units may have
evaporator fans that run continually or cycle on and off when
power is applied. If you have a unit that you notice the fan is
cycling, please see the operations sequence below.
During normal operation the evaporator fan may cycle and/
or pulse independently of the compressor. Consult Technical
Support at 1-844-724-CARE if you are unsure of the proper
function.
