The Time Divided Multi-cycle (TDM) system ( Stepper Valve) is used
to switch refrigerant flow. This improves temperature control and
energy efficiency. If its on the all evaporator mode it should work
properly, Using slightly more energy. If its on the freezer evaporator
only mode, there will be a Fridge no cool force on the fridge with the
Power Cool option. Monitor the fridge evaporator (s) temp by using
the Defrost Sensor(s). If the temp doesn’t decrease, then suspect the
Main PCB is not supplying signal to switch the diverter valve.
