Fresh Food Thermistor
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 31 and Cut-in and Cut-
out temperature chart on page 32.
To access: remove shelves, remove covers in upper
left and right rear corners (see Fan Assembly
Access section), disconnect wiring and thermistor is
accessible.
In order to check the Thermistor, refer to Page
16 to Access the Service Mode and page 17 on
reading the Binary Code to check the thermistor.
If you are experiencing the scrolling temp bars
described on page 31 then the Thermistor needs to
be removed and tested.
Plasma Cluster™
The Plasma Cluster™ ion air purifier uses ions to
eliminate airborne bacteria, mold spores, and food
odors without having to be replaced.
To access, remove (3) 1/4” screws securing
Plasma Cluster™ to refrigerator ceiling, lower
Plasma Cluster™ and disconnect wiring, cluster is
now accessible.
The cluster should measure approximately 100M Ω.
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power to unit using power
switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure
correct earth ground and polarization. After servicing, reconnect power using power switch.
