3) Remove the control box cover.
4) Plug the appliance back into the electrical outlet.
5) Move the power switch to the "ON" position.
6) Confirm 115VAC at the power switch. On 3-section models, also confirm proper supply
voltage at the receptacle box (115VAC for refrigerator/208-230VAC for freezer).

Startup/Cool Down–
There is a slight delay, cabinet temperature appears on display.
Comp, ConFM, EvapFM, and MH energize.
a)
EvapFM Diagnosis
:
Confirm EvapFM energizes. If not, confirm doors are closed
and DS engaged. Next, check for 115VAC at DSR #8 (LBU or GY) to #7 (W).
If 115VAC is not present, check DS continuity. If DS is engaged and contacts are
open, replace DS. If 15VAC is present, check for 115VAC at DSR #4 (DBU) to
neutral (W). If 115VAC is not present, check for 115VAC at DSR #6 (BK or W/BU) to
neutral (W). If 115VAC is present at DSR #6 (BK or W/BU) to neutral (W) and not at
DSR #4 (DBU) to neutral (W), replace DSR. If 115VAC is present at DSR #4 (DBU)
to neutral (W), check EvapFM blades for binding and EvapFM continuity.
b) Cabinet Light:
FGY CL
:
Diagnosis
: Open the door confirm CLS is in the ON position.
If not, move CLS to the ON position. CLS turns on. If CLS does not turn on, check
for 115VAC at both CLS (BK) wires to neutral (W). If 115VAC is present one 1
CLS (BK) wire and not the other, confirm power supply and continuity of CLS switch.
If power supply is ok, check CLS continuity. If CLS is engaged and CLS switch is
open, replace CLS. If CLS is engaged, contacts are closed, and 115VAC is present
at CLS (BK) and CL is not energized, replace CL.
FS/HS CL: Diagnosis
: Open the door (upper on HS) and confirm CL is energized.
If not, with the door open, check for 115VAC at DSR #5 (BK) to neutral (W) and DSR
#1 (V or Y) to neutral (W). If 115VAC is not present at DSR #5 (BK), confirm power
supply and continuity of power switch. If 115VAC is present at DSR #5 (BK) and not
present at DSR #1 (V or Y), check DS continuity. If DS is disengaged and contacts
are closed (DSR energized), replace DS. If DSR is de-energized and 115VAC is
present at DSR #5 (BK) and not at DSR #1 (V or Y) to neutral (W), replace DSR.
If 115VAC is present at DSR #1 (V or Y) and CL is not energized, replace CL.
c)
CM Diagnosis
: Cabinet temperature appears on display. If not, check for 115VAC at
CM L2 (BK) to CM N3 neutral (W). If 115VAC is not present, check power switch,
power cord connections, and breaker/fuse. Confirm wiring connections are secure
for both CM L2 (BK) (power supply) and CM N3 (W) (neutral). If 115VAC is present
and display is off, replace CM.
d)
Comp and ConFM Diagnosis
:
Confirm Comp and ConFM energize. If not, check
for 115VAC at CM C1 (R or V) to neutral (W). If 115VAC is not present, check CTh
status. See "II.D.Thermistor Check." If CTh ohm reading is in proper range, replace
CM. If 115VAC is present at CM C1 (R or V) to neutral (W), check for 115VAC at
CR #0 (GY or P) to CR #1 (W). If 115VAC is not present, check continuity of HPS.
If open, allow time for HPS to reset. If HPS does not reset, see "e) HPS Activation"
below. If HPS is closed and 115VAC is present, check for 115VAC at CR #4 (BK)
and CR #6 (R) to neutral (W). If 115VAC is present at CR #4 (BK) and not at
CR #6 (R), replace CR. If 115VAC is present at CR #6 (R) to neutral (W) and ConFM
