This is an MSD2356 side by side. It is running all the time and the
freezer is far too too cold but the refrigerator temperature appears
normal (possibly on the warm side) regardless of thermostat settings.
Any suggestions apart from the obvious, thermostat.

Can anyone provide info on how temperature is regulated in a typical
side by side setup. I am assuming the main thermostat regulates the
freezer temperature by controlling the comopressor. The refrigerator
temperature is controlled by regulating the airflow from the freezer
to refrigerator side. Is this correct?

Thanks,
Dave
