Important Safety Information
Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, damage to the appliance, or damage to property.
WARNING Indicates a hazardous situation which could result in death or
serious injury.
NOTICE Indicates a situation which could result in damage to the
appliance or property.
IMPORTANT Indicates important information about the use and care of the
appliance.
WARNING
This icemaker should be destined only to the use for which it has been expressly
conceived. Any other use should be considered improper and therefore dangerous. The
manufacturer cannot be held responsible for injury or damage resulting from improper,
incorrect, and unreasonable use. Failure to service and maintain the icemaker in
accordance with this manual will adversely affect safety, performance, component life,
and warranty coverage and may result in costly water damage.
To reduce the risk of death, electric shock, serious injury, or re, follow basic
precautions including the following:
• Only qualied service technicians should install and service this icemaker.
• This icemaker must be installed in accordance with applicable national, state, and local
codes and regulations.
• This icemaker requires an independent power supply of proper capacity. See the
nameplate for electrical specications. Failure to use an independent power supply of
proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring,
or component failure. This could lead to heat generation or re.
• THIS ICEMAKER MUST BE GROUNDED: This icemaker is equipped with a
NEMA5-15 three-prong grounding plug to reduce the risk of potential shock
hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet.
If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualied
electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not
remove the ground prong from the power cord and do not use an adapter plug.
• Do not use an extension cord.
• To reduce the risk of electric shock, make sure the power switch is in the "OFF" position
before plugging in or unplugging the icemaker.
• To reduce the risk of electric shock, do not touch the power switch or plug with damp
hands.
• Do not use an icemaker with a damaged power cord. The power cord should not be
altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result
in electric shock or re. To unplug the icemaker, be sure to pull the plug, not the cord,
and do not jerk the cord.
• Do not make any alterations to the icemaker. Alterations could result in electric shock,
injury, re, or damage to the icemaker.
• Do not place ngers or any other objects into the ice discharge opening.
5
WARNING, continued
• This appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
• Young children should be properly supervised around this appliance.
• Do not climb, stand, or hang on the icemaker or icemaker door or allow children or
animals to do so. Serious injury could occur or the icemaker could be damaged.
• Be careful not to pinch ngers when opening and closing the door. Be careful when
opening and closing the door when children are in the area.
• Do not use combustible spray or place volatile or ammable substances near the
icemaker. They might catch re.
• Keep the area around the icemaker clean. Dirt, dust, or insects in the icemaker could
cause harm to individuals or damage to the icemaker.
NOTICE
• Protect the oor when moving the icemaker to prevent damage to the oor.
• Follow the instructions in this manual carefully to reduce the risk of costly water
damage.
• In areas where water damage is a concern, install in a contained area with a oor drain.
• Install the icemaker in a location that stays above freezing. Normal operating ambient
temperature must be within 45°F to 100°F (7°C to 38°C).
• If using the optional drain pump (HS-0248), test its operation every time the icemaker is
cleaned and sanitized. See "IV.E.2. Drain Pump Check" for details. If the optional drain
pump is not operating properly, water could back up and overow, leading to costly
water damage.
• To help ensure that the storage bin drain remains clear, follow the instructions in "VI.C.
Storage Bin Drain" once every 3 months or as often as necessary for conditions. If
the storage bin drain becomes clogged, water could build up in the bin and overow,
leading to costly water damage.
• If water collects in the bin and will not drain, turn off the icemaker and close the water
supply line shut-off valve. Locate and resolve the issue.
• To help protect against unseen water issues, this icemaker features a drip tray and
emergency overow hose. See Fig. 1. If there is water in the drip tray, coming out of
the reservoir emergency overow hose, or seeping from the base of the icemaker, turn
off the icemaker and close the water supply line shut-off valve. Locate and resolve the
issue. Failure to do so could lead to costly water damage.
• Do not leave the icemaker on during extended periods of non-use, extended absences,
or in sub-freezing temperatures. To properly prepare the icemaker for these occasions,
follow the instructions in "VII. Preparing the Icemaker for Periods of Non-Use."
• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear
of obstruction.
• Do not place objects on top of the icemaker.
• The storage bin is for ice use only. Do not store anything else in the storage bin.

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 6minutes 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. Rell: The oat-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 lls 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.

2. Auxiliary Codes A-2 and Later
After the power switch is placed in the "ON" position, the steps in the sequence are as
outlined below.
a) Fill Cycle
LF/S and UF/S open, BCH and WV energize. LF/S closes. Nothing happens at this time.
Reservoir continues to ll until UF/S closes.
b) Freeze Cycle
UF/S closes. BCH remains energized. WCR, TDR, GM, FM, CR, and Comp energize. WV
de-energizes. Ice production starts 4 to 6minutes after Comp energizes depending on
ambient and water conditions. F/S controls WV to rell as needed during the freeze cycle.
The freeze cycle continues until BC shuts down the icemaker or power is turned off to
the icemaker. Rell: As ice is produced, the water level in the reservoir drops and UF/S
opens. When UF/S opens, a latching circuit through LF/S and WCR keeps WCR, TDR,
GM, FM, CR, and Comp energized. When LF/S opens, WCR de-energizes, cutting power
to TDR terminal #5 (O wire) and starting FT. WV energizes. Water lls the reservoir, UF/S
closes. WCR energizes, restoring power to TDR terminal #5 (O wire) and resetting FT.
WV de-energizes. If UF/S remains open longer than 90 seconds, FT terminates, cutting
power to TDR terminal#9 (R wire). GM, FM, CR, and Comp de-energize. WV remains
energized until UF/S closes.
c) Bin Control Thermostat Shutdown
Ice lls storage bin to level of BC. BC opens within 10 seconds after ice contact. When
BC opens, BCH remains energized. WCR, TDR, GM, FM, CR, and Comp de-energize.
When ice level lowers and BC closes, the icemaker starts operating again.
