4. Defrost Termination

10) Check that the components restart after defrost termination.

Refrigerator:

a) Auxiliary Code F-6 and Earlier: DTh reaches 40°F (4.4°C) Comp and ConFM

(CMC1 (R or V)) energize. If not, check DTh status. See "II.D.Thermistor Check."

IfDTh ohm reading is in proper range, and components do not energize, check for

115VAC at CM C1 (R or V) to neutral (W). If 115VAC is not present, replace CM.

If115VAC is present, check component continuity and replace as needed.

b) Auxiliary Code F-7 and Later: DTh reaches 44°F (6.6°C), Comp and ConFM (CM

C1 (V)), and EvapFM (CM F5 (W/BU)) energize. If not, check DTh status. See

"II.D.Thermistor Check." If DTh ohm reading is in proper range, and components

do not energize, check for 115VAC at CM C1 (V) and CM F5 (W/BU) to neutral

(W). If 115VAC is not present, replace CM. If 115VAC is present, check component

continuity and replace as needed.

Freezer:

a) Auxiliary Code F-7 and Earlier: DTh reaches 59°F (15°C) or 45°F (7.2°C). 3-min.

later, Comp and ConFM (CM C1 (RorV)) and EvapFM (CM F5 (Y or W/BU))

energize. If not, check DTh status. See "II.D.Thermistor Check." IfDTh ohm reading

is in proper range, and Comp, ConFM, or EvapFM do not energize, replaceCM.

12min. after Comp, ConFM, and EvapFM energize, cabinet temperature appears on

CM. If components fail to start, check continuity, replace as needed.

b) Auxiliary Code F-8 and Later: DTh reaches 45°F (7.2°C). 3-min. later, Comp and

ConFM (CM C1 (V)) and EvapFM (CM F5 (W/BU)) energize. If not, check DTh status.

See "II.D.Thermistor Check." IfDTh ohm reading is in proper range, and Comp and

ConFM (CM C1 (V)), or EvapFM (CM F5 (W/BU)) do not energize, replaceCM.

12min. after Comp, ConFM, and EvapFM energize, cabinet temperature appears on

CM. If components fail to start, check continuity, replace as needed.
