2. The condition of DEFROST operation

-It runs regularly according to the defrost cycle with adding up the plug in time.

-When the defrost starting time comes, COMPRESSOR must be turned off and the defrost operation cycle begins to run according to the conditions as the below 1 and 2 after checking the temperature by

DEFROST SENSOR.

Cond ition 1(In case the temperature checked by DEFROST SENSOR is low than 23℉); Defrost Heater (Max. 40Min. running) runs by that time DEFROST-SENSOR sensor 53℉ and COMPRESSOR runs after 10minutes pauses.
