3 Technical Descriptions
3.1. Compressor Operation
Compressor is controlled by the difference between detected temperature of the freezer temperature sensor and preset tempera-
ture of the freezer compartment.
It runs for 10 minutes when plugged in, but it is forced to be stopped for 10 minutes once plugged off to prevent failure.
3.2. PC Damper Operation
PC damper is controlled by the difference between detected temperature of the fridge temperature sensor and preset temperature
of the fridge compartment.
PC damper is closed during defrost.
3.3. Fan Motor Operation
Fan motor is turned off while compressor stops.
Fan motor is turned on while compressor is running.
If damper is open, fan motor is turned on even though compressor has stopped.
3.4. Defrost Operation
Defrost does not activate in the following conditions.
• For 120 minutes after Super Cool Mode starts
• For 120 minutes after Super Freeze Mode starts
• For 120 minutes after Flash Freeze Mode starts
