6) 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. 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.
Diagnosis:Check that GM, FM, and Comp energize. If not, check the power switch,
STS, BC assembly, GM external protector, GM windings (check when GM is cool), GM
capacitor, voltage to FM, FMwindings, fan blade binding, voltage on CR, PTC relay,
voltage on Comp external protector, Comp terminals, and Comp windings. If optional
drain pump HS-0248 is installed, see "IV.E. Optional Drain Pump HS-0248." If GM
starts, but the auger does not turn, check the spline coupling between the auger and
GM.
7) Shutdown (bin full) – Ice lls storage bin to level of BC. BC opens within 10 seconds
after ice contact. BCH remains energized. GM, FM, CR, and Comp de-energize.
Diagnosis: When the icemaker is running, hold ice in contact with BC bulb. If the
components fail to de-energize within 10seconds, check BC. See "IV.C. Bin Control
Check."
