Icemakers
¾ The icemakers operate in much the same way as previous bottom freezer models
with one significant difference: the icemakers are controlled by either the main
control board or the door control board. The board inside the icemaker does NOT
control operation.
¾ The icemaker in the door is controlled by the door control board.
¾ The icemaker in the freezer is controlled by the main control board.
¾ These boards will monitor the mold thermistor, rake and feeler arm sensors to
operate the rake motor, heater and water valve.
¾ Like previous electronic icemakers, these new icemakers will run “Power On
Diagnostics”, however, this will occur if the mold temperature is above 40˚F*
rather than 50˚F like previous models.
* Values are approximate and preliminary
¾ The thermistor has the same resistance
value as previous electronic icemakers.
