2007 Itasca. Dbl door fridge Norcold 1211IMWPM.
The freezer is freezing, but the fridge part not so much.
On AC, setting temp and # flashes.

Fault Code - "Temperature number flashes when SET TEMP button is pushed."
Fault Code means: The refrigerator is operating on the 'Back up Operating System'.

** I have no idea what that means, 'operating on back up system'.
** What is the fix??

thank you in advance.
cheers

Backup Operating System (BOS)
The backup operating system (BOS) is an
electronically controlled duty cycle. It maintains the
refrigerator in operation if the thermistor is
disconnected or fails. The BOS maintains cooling by
controlling the heat source selected. When the
refrigerator is operating in BOS, the length of the
cooling cycle is regulated by time rather than
regulated by temperature.
To accomplish this, the BOS adjusts the length of the
cooling cycle according to the temperature setting
selected by the user; the higher the temperature
setting, the longer the cooling cycle. For example, if
the temperature setting is set to 5, raising the setting
to 6 will lengthen the cooling cycle, making the
cabinet colder
