WARNING
!
Thermistor
Plasma Cluster
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless
test procedures require power to be connected. Ensure all ground wires are connected before certifying unit as
repaired and/or operational.
The unit uses a thermistor (type of resistor
whose resistance varies with temperature) to
control temperature. The temperature of the
thermistor equates to a resistance that is fed
back to the low voltage control board. Refer
to resistance vs. temperature chart on Page
12 and Cut-in and Cut- out temperature
To access: remove top shelf if required,
remove covers in upper left and right
rear corners (see Fan Assembly Access
section), disconnect wiring and thermistor is
accessible.
Fresh Food Thermistor
To access, remove (3) 1/4” screws securing
Plasma Cluster™ to refrigerator ceiling, lower
Plasma Cluster™ and disconnect wiring,
cluster is now accessible.
Plasma Cluster™
The Plasma Cluster™ ion air purifier uses
ions to eliminate airborne bacteria, mold
spores, and food odors without having to be
replaced.
