e)Initial Harvest Cycle Termination Diagnosis: When the thermistor reaches 48°F
(9°C), CB reads 3.9 kΩ from the thermistor and turns harvest termination over to the harvest timer (S4 dip switch 1 & 2). Check discharge line temperature. For a thermistor check, see "II.F. Thermistor Check." If
Switch Check and Cleaning." If FS is closed, CB proceeds to the next cycle. If not, replace CB.
Note: The minimum total time allowed by CB for a complete harvest cycle is 2 min. Maximum harvest time allowed is 20 min.
NOTICE! On models with "G" control board and no harvest pump timer relays,
S4 dip switch 7 must remain off. Otherwise, PM energizes in reverse direction the last 50 seconds of harvest and empties water from water tank.
6)Freeze Cycle – LED 1 is on. Comp and FMR continue. PM, FM, and LLV energize. WV and HGV de‑energize. Appliance is held in freeze by a
a)Freeze Cycle Diagnosis: Confirm Comp and FMR continue. Confirm that
PM, FM, and LLV energize. Confirm WRV opens. Next, confirm WV and HGV de‑energize. During the first 5 min. of freeze, confirm evaporator is cooling. If not, confirm WV
LLV and FM energize, TXV and HM operate correctly, WRV opens, Comp is efficient, and refrigerant charge is correct. See "VIII.A. Specification Sheet" and "VIII.B. Performance Data."
b)Comp and FMR Diagnosis: If Comp and FMR
K1 #1 (V) or #9 (V) to neutral (W). If 115VAC is not present and LED 1 is on, replace
CB. If 115VAC is present, check for 115VAC at CR or MC coil. If 115VAC is present, check CR or MC coil and contact continuity. Replace as needed. If CR or MC is ok, check Comp external overload, start relay, and start and run capacitors. Next, check Comp motor winding continuity. If Comp is energized but evaporator is not cooling, check for an inefficient Comp. See "VIII.B. Performance Data." If Comp is energized but FMR is not, check for 115VAC at the FMR junction box. If 115VAC is not present, check icemaker wiring connections. If 115VAC is present, check for voltage at condenser unit. If 115VAC is not present, check field wiring connections. If 115VAC is present, check FMR capacitor, motor winding, and fan blade for binding.
c)WV and HGV Diagnosis: If WV is energized, check for 115VAC at CB K1 #6 (O) to neutral (W). If 115VAC is present after PM energizes, replace CB. If 115VAC is not present, replace WV (bypassing). If HGV did not
