Icemaker Sequence
¾ The normal icemaker sequence is to fill the mold with water, wait until the water
is frozen, harvest the ice and then repeat the cycle.
¾ To accomplish this sequence, three cycles are defined:
Freeze, Harvest and Water Fill.
¾ The Freeze cycle begins after a fill, when the mold temp drops below 32˚F* and
will last for a minimum of 50 minutes*.
¾ After the Freeze cycle conditions have been met and the feeler arm is in the “out”
position, a harvest cycle will be initiated.
¾ At the start of the Harvest cycle, the heater will turn on and remain on until the
mold temperature is at least 36˚F* (minimum heater time is 1 minute)*. The
heater will cycle to maintain at least 36˚F* during harvest.
¾ Once 36˚F* is reached, the rake motor will turn on, making one revolution to
eject the cubes while the control monitors rotation through the home position.
¾ When the rake motor is back at the home position, the Water Fill cycle starts by
cooling the mold to 40˚F*.
¾ The icemaker then fills with water for 5.1 seconds (no additional fills are used)*
¾ The icemaker then starts another Freeze cycle.
¾ Average time from fill to fill is 60-70 minutes.
* Values are approximate and preliminary
