Ice Operation – Basic Logic
The new BM Ice in Door model has multiple and unique logic and calculations that are
accomplished with the board, the control settings, and feedback from thermistors.
However, the new ice door does not have its own thermistor and therefore calculations
are accomplished with input from the FF and FZ thermistors.
The new BM does utilize a dedicated blower fan to send cold air up from the freezer,
through a channel and into the ice section.
Ice Making/Harvest mode: this mode looks for water valve or dispenser action within a two
hour period of time. ( 4 minute response time) If seen, the ice section temperature should be
approximately 0° F degrees.
Ice Storage mode: if above activity is not detected, the temperature in the ice section could
raises as high as approximately 15° - 25°F.
Ice Hardening mode: this mode tries to account for high number of door openings and maintain
similar temperatures as the ice storage mode
Remember that temperature in the ice section is tied to the control settings so the
warmer the FZ section is set for, the warmer the ice section. A freezer setting below “5”
will produce the warmest ice section temperature.
NOTE: Ice stored for more than 10days could clump.

Abnormal modes:
When the unit is in liner protection mode, the ice box fan will run in low
speed (along with the evaporator fan in low speed)
If the FF damper has been open for 2 hours continuously and the unit is in
ice storage mode, the icebox fan will turn on at low speed and run until the
damper closes
Ice Fan – More Basic Operation
Ice Hardening mode: Fan on high speed, while compressor is on.
Ice Storage mode: Fan on low speed, while compressor is on.
Fan speed and on-time are calculated with a multitude of algorithms.
Changes to the time and speed can vary.
Changing the FZ temp settings will prompt new calculations.
Ice fan off during all phases of defrost. (Defrost, Dwell & Post-dwell)

Humidity Sensor - Testing
Pins 1 to 2 --- constant 5 vdc.
Pins 1 to 3 --- varies with humidity from about 1.11 vdc to 3.62 vdc.
The higher the humidity the higher the output voltage. Any output
higher than @ 4 vdc or lower than 1 vdc, the sensor is bad
F.I. Testing – A reading of appx 0-100 would be considered normal.
A reading of 150 or higher indicates a failed humidity sensor.
NOTE: A failed sensor could keep the heaters on for longer periods.
