B. Sequence of Operation
1. Auxiliary Codes A-1 and Earlier
After the power switch is placed in the "ON" position, the steps in the sequence are as 
outlined below. 
a) Freeze Cycle
BCH, GM, FM, CR, and Comp energize. 
NOTICE! Some units contain a sticker that 
states: "The bin control heater has been disconnected. DO NOT reconnect the 
bin control heater." In this case, leave BCH disconnected or replace BC assembly 
with 3A2561A03. 
Ice production starts 4 to 6 minutes after Comp energizes depending 
on ambient and water conditions. The freeze cycle continues until BC shuts down the 
icemaker or power is turned off to the icemaker. 
Refill: The float-operated WV allows 
water into the reservoir as needed to continue the icemaking process. If the water supply 
is cut off or GM stops during the freeze cycle, the cold evaporator temperature causes 
STS to open and de-energize all components except BCH and optional drain pump 
HS-0248.
b) Bin Control Thermostat Shutdown
Ice fills storage bin to level of BC. BC opens within 10 seconds after ice contact. When 
BC opens, BCH remains energized. GM, FM, CR, and Comp de-energize. When ice level 
lowers and BC closes, the icemaker starts operating again.
