* Approximate values
Possible Cause:
The refrigerator is operating on AC
electric power. The thermistor has been
sensed as inoperable, so temperature
is being controlled via backup operating
system.
Possible Cause:
The refrigerator is operating on propane
gas. The thermistor has been sensed
as inoperable, so temperature is being
controlled via backup operating system.

Are
wires and
connector
good?
YES
Clean or repair as needed.
NO
Check resistance at thermistor connector
with the thermistor packed in ice.
Check thermistor wire
assembly and connctor
for broken/dirty connections.
Is
thermistor
wire plugged
in?
NO
Plug in thermisor wire.
YES
