REFRIGERATOR/FREEZER COMBO COOLING OPERATION

1. Power On:   Compressor, condenser fan 

and the freezer evaporator fan turns on. The 

refrigerator evaporator fan remains off. The 

controller continues to monitor the freezer 

temperature sensor (bottom thermistor) until 

the bottom sensor temperature (BT) reaches 

the freezer set temperature (FST). 

2, When the TT reaches FST-2.78°C, the 

controller stops the freezer evaporator fan 

and measures the refrigerator temperature 

- TT (top thermistor) against the refrigera-

tor set temperature (RST).  If the TT > RST, 

then the compressor and the condenser fan 

remain on while the top evaporator fan turns 

on.

3. The controller continues to monitor the 

TT until the TT < RST, then the refrigerator 

evaporator fan motor stops.  The controller 

checks the BT again, if the BT > FST, the 

freezer evaporator fan turns on while the 

compressor and condenser fan remain on.

Repeat step 3 until both TT and BT are 

below the set temperatures minus differen-

tials (i.e. TT < RST and BT < FST).  If both 

TT and BT are the below set temperatures 

minus differentials, then all the motors and 

compressor stop. Once the compressor is 

off, the controller continues to monitor the TT 

and BT.  

The compressor fan, condenser and the 

related  evaporator fans turns on when the 

TT is higher than the RST or the BT is higher 

than the FST.

If the TT > RST , but the BT < FST, then the 

controller turns on top evaporator fan only.  

The compressor, condenser fan and bottom 

evaporator fan remain off. 

The controller continues to monitor the TT 

and BT. If the BT > FST, then the compres-

sor and condenser fan turn on, while the top 

evaporator fan continues to run.  If the BT 

< FST  and the TT > RST, then the freezer 

evaporator fan turns on (the compressor and 

condenser fan remain off as long as BT < 

FST).
