a) Pump-Out Diagnosis: In the freeze cycle before pump-out (see table above), after
5 min. of freeze disconnect CB black K5 connector (FS connector). Check that PM
stops and re-starts. Next, check that PM rotation is correct (water flowing down the
drain through CV).
b) CB Diagnosis: Confirm LLVs de-energize. If LLVs are energized with LEDs 1, 3, and
2 on, replace CB. If PM does not stop and re-start, check that CB LEDs 1, 3, and
2 are on. If not, replace CB. If LEDs 1, 3, and 2 are on and PM does not energize,
check for 115VAC at CB K1 #5 (DBU) to neutral (W). If 115VAC is not present,
replace CB.
c) X10 and X11 Relay Diagnosis: If 115VAC is present at CB K1 #5 (DBU), check that
X10 relay is de-energized. If not, check X11 relay status. If X11 relay is energized,
replace CB. If X11 relay is de-energized and X10 relay is energized, replace
X11 relay (contacts sticking). If X10 relay is de-energized, check for 115VAC at
terminal #5 (DBU) to neutral (W) and terminal #1 (DBU) to neutral (W). If 115VAC
is present on terminal #5 (DBU) and not on terminal #1 (DBU), replace X10 relay.
If 115VAC is present on X10 terminal #1 (DBU) and PM is not energized check for
115VAC at X12 terminal #5 (DBU) to neutral (W) and X12 terminal #3 (DBU) to
neutral (W).
d) X12 Relay Diagnosis: If 115VAC is present on X12 terminal #5 (DBU) and not on
X12 terminal #3 (DBU), check for 115VAC at X12 terminal #8 (P) to X12 terminal
#7 (W). If 115VAC is not present, check CB K1 pin #2 (P) wiring for loose connection.
If 115VAC is present and X12 is not energized, check coil continuity. Replace as
needed. If X12 is energized and X12 terminal #3 (DBU) does not have 115VAC,
replace X12 relay (contacts sticking).
e) PM Diagnosis: If 115VAC is present on X12 terminal #3 (DBU), PM should be
energized and rotating in pump-out rotation. If PM is de-energized, check PM
capacitor, motor windings and impeller for binding. If energized and rotating correctly,
make sure the drain line is not clogged and that CV is clean and operating properly.
Confirm FM and LLV de-energize. If FM or LLV are energized with LEDs 1, 3, and 2 on,
replace CB.
8) Normal Harvest Cycle – Same as the initial harvest cycle. Return to step 5a) above.
Note: Appliance continues to cycle until BC is satisfied or power is switched off or
freeze-time correction cycle is initiated. The appliance always restarts at the 1-min.
