NEW ICE MAKER CONTROL BOARD (#6100499)

NOTE: Due to a quality improvement, the new control board will replace the older design (#2185947).

If you are replacing control board #2185947, please read the improvements listed below. If you are replacing control board #6100499, you may disregard the following information.

There are no differences in mounting or wiring the new control board. Improvements were made to support low voltage applications.

Additional improvements include the following:

•A 15-minute minimum, and 25-minute maximum, ice making cycle time limit. This eliminates the production of ice slabs that are too thin or too thick. Control boards with Code Date MGR/0245, (45th week, 2002), or higher, will allow ice thickness adjustments by moving the jumper at P4 (see “Adjusting The Ice Thickness” on page 8-3).

•During a harvest, the water valve “on time” is now limited to 1 minute to reduce water usage. This also eliminates the condition of the water valve being ener- gized for an unlimited amount of time if the evaporator thermistor is not located correctly, or if the reversing valve has failed or is unplugged. If the evaporator thermistor is unplugged, a 25-minute de- fault freeze, and 4-minute harvest inter- val will occur.

If the unit stays in harvest mode for more than 16 minutes, the unit will go into a failure mode, shutting the unit down, and flashing the LED light. To get out of failure mode, shut the unit off, and then back on again. This will reset the control board. If the failure was not corrected, the unit will return to failure mode when the unit reaches it’s 16-minute cycle again. If this occurs, find the cause of the failure, and repair it, then unplug the unit to reset the board.

•The diagnostic mode sequence was changed, moving the bin and evaporator thermistor checks to the beginning of the sequence. The old boards had these checks at the end of the sequence.

•Whenever the unit has reached a failure mode, the LED will flash, and the unit will shut down. If the failure was caused dur- ing a harvest cycle which lasted more than 16 minutes, the LED will remain flashing on & off in half-second incre- ments. If the failure is caused by a faulty bin thermistor, (not detected), the LED will remain flashing on & off in 1-second increments. These are the only two fail- ures that cause the unit to reach a shut- down failure mode.

•During the Clean cycle, the control board performs the diagnostics first. If the bin thermistor is not detected, the LED will flash two times. This is followed by a 3-second delay. If the evaporator ther- mistor is not detected, the LED will flash on five times. This will be followed by a 3-second delay. The LED will then come back on, and remain on for the remainder of the Clean cycle, and until the unit is turned back on.

The following check can be done on the board & thermistors:

-Unplug either thermistor electrical connection.

-Press the Clean switch. The LED should flash as described above, de- pending upon which thermistor is un- plugged, or if both are unplugged.

For step-by-step operation, see the flow chart on page 6-5.
