8.6.4 Temperature Probe
Each refrigerated zone has one 10K ohm NTC probe,
which senses compartment temperature. Sensing

the evaporator fan behind the cover panel. Defrost
termination probe (evaporator). Additionally, low
temperature products may have a defrost
termination probe inserted into the fins of the
evaporator.
