20 1 . "E" and "G" Control Boar d without Harvest P ump Timer Diagnosis 3) P ow er On : T ur n on the power suppl y , then mov e the control s witch to the "ICE" position. A 5-sec. delay occur s. • "E" Contr ol Board: CB red "PO WER OK" LED tur ns on.
21 5) Initial Harvest Cy c le – LEDs 1, 4, and 2 are on. WV continues. Comp , FMR, and HGV energiz e. CB monitor s the warming of the ev aporat or via the ther mist or locat ed on the suction line. When the thermistor r eaches 48°F (9°C), CB reads 3.
22 b) Comp and FMR Diagnosis : If Comp and FMR de-energiz e once freeze begins , check that appliance has not shut of f on HPS ("POWER OK" LED of f). If so , chec k "3)b) HPS Diagnosis" abov e. If "POWER OK" LED is on, chec k for 1 1 5V AC at CB K1#1 (V) or #9 (V) to neutr al (W).
23 h) F r eeze T ermination Diagnosis: Af ter 5 min. in freeze , disconnect CB K5 FS connector . 1 5 sec. later appliance should s witch out of the freez e cy cle (1 5 second dela y af ter FS opens bef ore t er minating the freez e cy cle). If appliance remains in freez e longer than 1 5 sec.
24 8) Normal Harv est Cy c le – Same as the initial harvest c y cle. Return to st ep 5 abov e. Note: Appliance continues t o cy cle until BC is satis ed or power is turned of f .
25 2. "G" Control Boar d with Harvest P ump Timer Diagnosis 3) P ow er On : T ur n on the power suppl y , then mov e the control s witch to the "ICE" position. A 5-sec. delay occur s. CB red "PO WER OK" LED and gr een "BC CLOSED" LED turn on.
26 5a) Initial Harvest Cy c le – LEDs 1, 4, and 2 are on. WV and X1 1 r ela y continue . Comp , FMR, HGV , and X1 0 rela y energiz e . CBmonitor s the warming of the e v aporat or via the ther mist or locat ed on the suction line. When the thermistor r eaches 48°F (9°C), CB reads 3.
27 If 1 1 5V A C is present on t er minal #3(P) and not on t erminal #5 (Y), replace X1 0 rela y . If 1 1 5V A C is present on X1 0 rela y ter minal #7 (Y) and PM is not ener giz ed, check f or 1 1 5V A C at X1 0 rela y terminal #4 (R) to neutral (W) and t erminal #6 (DBU) to neutr al (W).
