4-2-5. If defrost does not operate (F,R DEF Heater)

- If defrost has trouble, select the self-diagnostic function to detect the error of defrost heater before

Power Off. (Check the function with the self-diagnostic function)

R DEF ERROR

F DEF ERROR

Start

Are the all deforst

heater normal?

Check the bimetal, heater
disconnection, wiring connection etc.

Refer to self-diagnostic

function in the manual

Replace the
applicable sensor

manual operation for a certain time

Manual defrosting of fresh food

and freezer compartments

operate simultaneously.

Is the temperature of

defrost sensor lower

than 53.6

Is defrost sensor by

self-diagnostic normal?

Is power applied to

each defrost heaters?

Is connection terminal of

MAIN PCB part normal?

Recheck the applicable

sensor.

than 50

℉(10℃), 53.6℉(12℃) by

the heating from heater, heating

would be finished and will return

to cooling operation after a pause.

Check bimetal, heater itself,

disconnection etc.

Replace failure Relay or

replace PCB ASS'Y

Does the system return

to cooling operation after

heating for specified time?
