The articulating mullion contains a DC heater to
keep the mullion from forming condensation. The
heater ON time is based on the relative humidity
percentage calculated by the main board. The
calculation is based on the feedback provided by
the humidity sensor. The top of the articulating
mullion engages with the mullion striker to open
and close the mullion. When the mullion is in the
closed position, the mullion provides the mating
surface for the right door. If the articulating
mullion does not make contact with the mullion
striker, the dispenser door will need to be raised.
Articulating Mullion Diagnosing
The heater in the mullion has a resistance of 24
ohms.
