B. Sequence of Operation
This icemaker utilizes a thermostatic bin control to switch the gear motor, fan motor, and
compressor on and off as needed. This icemaker utilizes a float-operated water valve in
the water reservoir to allow water into the icemaker as needed. After the power switch is
placed in the "ON" position, the sequence is as follows:
1. Freeze Cycle
GM, FM, CR, and Comp energize. As the water in the evaporator cools, ice starts
forming within 4 to 6 minutes. This time frame depends on the inlet water and ambient
temperature conditions.
The float-operated water valve allows water into the reservoir as needed to continue the
ice making process. This continues until BC shuts down the icemaker or power is turned
off to the icemaker.
2. Bin Control Thermostat Shutdown
Ice fills storage bin to level of BC. When BC opens, GM, FM, CR, and Comp de-energize.
When ice level lowers and BC closes, the icemaker starts operating again.

When BC opens, the icemaker shuts
down. When BC closes, the icemaker
starts operating again.
