5) Freeze Cycle LED 1 and 4 are on. Comp, FMRs, and PM remain energized (CB K1
connector pin #5 (DBU wire) de-energizes and K1 connector pin #4 (R wire) energizes
to prevent PM interruption). LLVs energize. WV1 and LED 4 energize for 1 min. HGVs,
X10, X11, and X13 relays de-energize.
Rell LEDs 1 and 4 are on. The KMS-1401MLJ uses a single F/S with a double
F/S, UF/S rell initiation oat switch selector setting (S5 dip switch1) and is set for
1 rell (S5 dip switch 2 through 5). When the freeze cycle starts, CB monitors UF/S.
No UF/S exists on the KMS-1401MLJ, therefore CB reads an open UF/S immediately
when the freeze cycle starts and initiates a rell (CB energizes WV1 through X10 relay).
Since there is no UF/S to close and terminate the rell, the rell lasts for the maximum
1-minute. During the 1-minute rell, LED 4 is on. Comp, FMRs, LLVs, and PM remain
energized.
Freeze Termination LED 1 is on. The icemaker is held in freeze by a 5-minute short
cycle protection timer. When F/S opens, the freeze cycle terminates.
Diagnosis: Minimum freeze time is 5 minutes. During the rst 5 minutes of freeze,
conrm that Comp, FMRs, PM, and LLVs are energized, WV1 is energized for 1 min.,
and HGVs and WV2 are de-energized and not bypassing. The evaporator temperature
should be dropping. Make sure TXVsand HM are operating properly. Check that DV is
not leaking by (water owing down the potable drain). Check for proper unit pressures
(see "III.C. Performance Data") or an inoperative Comp. Disconnect the black K5 F/S
connector. When 5 or more minutes have elapsed in the freeze cycle, the icemaker
should switch out of the freeze cycle. After the icemaker switches out of freeze,
reconnect the black K5 F/S connector to CB. If the icemaker remains in freeze with F/S
disconnected, replace CB. To check F/S, see "IV.D. Float Switch Check and Cleaning."
Note: Normal freeze cycle will last 30 to 35 minutes depending on model and
conditions. Cycle times and pressures should follow performance data provided in
this manual. See "III.C. Performance Data."
