Information
Ò
Check of Cooling Fan, make sure that perform the check while Forced-Operation is selected.Ó
1. On OFF of COMP, cooling FAN of the Freezer (F-FAN), cooling FAN of the Refrigerator(R-FAN), COMP,
and COMP COOLING FAN maintain OFF state. But, for some time,
R-FAN may be operated by the natural defrosting function in spite of COMP OFF.
(The operation of R-FAN depend on the temperature of the Refrigerator.)
2. In spite of Forced-Operation state, R-FAN is not always ON (including normal operation).
When the temperature of the Refrigerator reaches the set temperature, R-FAN maintains OFF state.
3. When Doors of the Freezer and Refrigerator Open and then Close, each FAN operates after delay.
It means that, on DOOR OPEN during FAN operation, FAN stops immediately and on Close,
FAN operates after 1-minute delay (when the ambient temperature is more than 35 ).
(1) When FAN of the Freezer (F-FAN) does not operate (and COMP is operated normally
by the temperature),
COMP is OFF?
