1) Move the power switch to the "OFF" position.
2) Unplug the appliance from the electrical outlet.
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) Conrm 115VAC at the power switch. On 3-section models, also conrm proper supply
voltage at the receptacle box (115VAC for refrigerator/208-230VAC for freezer).
1a. Refrigerator: Auxiliary Code F-6 and Earlier
7) Startup/Cool Down–There is a slight delay, cabinet temperature appears on display.
Comp, ConFM, EvapFM, and MH energize. 2-hr defrost timer starts.
a) EvapFMDiagnosis: Conrm EvapFM energizes. If not, conrm doors are closed
and DS engaged. Next, check for 115VAC at DSR #8 (LBU or GY) to DSR #7(W).
If115VAC is not present, check DS continuity. If DS is engaged and contacts are
open, replace DS. If 115VAC 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 (FGYCR and FGYCL) Diagnosis: Open the door and conrm
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 at 1 CLS(BK) wire and not at the other, conrm 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 conrm 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), conrm 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. Conrm 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.
