ICE MAKER

WARNING

DO NOT cycle ice maker by hand. This will cause damage to the ice maker.

Freeze cycle

•Neither ice maker relay is energized.

•Unit is cooling down to 15°F set-point.

•The unit may cycle on and off as the ice maker is pulling down to maintain the proper refrigerator/freezer temperatures.

•The minimum freeze time as permitted by the board is 20 minutes (CO2175F) or 75 minutes (CO2175DWR).

Harvest cycle 1

•Relay 6 is energized for 30 seconds and relay 7 is energized for 10 minutes. The bin arm must be fully lowered and the lower drawer closed for this cycle to begin.

Harvest cycle 2

•The lower drawer must remain closed for the cycle to continue. In the event that it is opened the timers will hold until the drawer is closed. At that time they will resume the cycle. If the unit has a door rather than a drawer it is not effected.

•Relay 6 is now off and the ice maker is powered completely by relay 7. This occurs at approximately the 2 o'clock position.

•Ejector blades stall on the ice until the heater releases it from the mold.

•This cycle will last a few minutes.

Water fill cycle

•At about the 10 o'clock setting the water valve is energized for about 7 seconds to refill the mold.

•At the conclusion of the cycle the blades stop at the 12 o'clock position.

Harvest cycle 3

•Following the water fill relay 7 remains energized for the balance of the 10 minutes that it needs to remain on.

Storage mode

•The bin arm is in the UP position, either held in place by the ice or manually raised. The board continues to signal the ice maker to harvest so relays 6 and 7 will energize; however, with the arm up the cycle will not begin.

Review the following notes for general information before reading the schematics.

These are some additional general notes and exceptions:

•The unit is equipped with a four-minute compressor off cycle.

•The controller is designed to be able to show and set the refrigerator set-point. Based on this input the controller tries to maintain the perfect balance of refrigeration to keep the refrigerator and freezer at acceptable temperatures. For this reason the refrigerator temperature may fluctuate from 34°F to 40°F depending on the freezer load. The freezer will also float in a -10 to +10 range depending on the refrigerator load and usage.

•The ice harvest will be initiated when the ice maker temperature drops to 15°F. Through a built-in timer the ice maker can only harvest once every 20 minutes (for CO2175F) or 75 minutes (CO2175DWR) at a maximum so if the temperature is at 15°F it will not necessarily cycle depending on when the previous cycle had occurred.

•The drain pan heater will energize five minutes before and after the hot gas portion of the defrost cycle (not on CO2175DWR). This time is not included in the defrost total length.

•If the unit is turned off while the ice maker is in a harvest mode, the display will flash OFF while the ice is harvesting

— up to 10 minutes.
