Sensors
Condenser sensor (white) and suction line sensor (brown) are
thermistors rated 1k ohm at room temperature.
S Condenser sensor signals the circuit
board for fan cycling and also serves
as the high temperature safety shut
down. The red “Error LED” will flash
on and off every second, during high
temperature safety shut down. Prod-
uct is functionally shut down. Reset
procedure must be performed to re-
start product operation.
S Suction line sensor signals the circuit
board the suction line temperature, to
control ice bridge thickness. Also the
sensor serves as suction line high
temperature signal (Cuber has 6 min-
utes to reduce suction line tempera-
ture to 40°F (4.4°C) in the freeze
mode). The red “Error LED” will be
steady on ...should this time frame not
be met, product is functionally inop-
erative during this safety shut down.
Reset procedure must be performed
to restart product operation.
