Compartment Temp

 – The sensor controls fan/compressor on/off to main-

tain temp 

Ambient Sensor  

Fan Speeds – Below 60 degrees condenser fan is off  
Defrost Timing – The warmer the room the more often the defrost  

How to Check Sensor Resistances 

Make 

ice slurry.  To do this, fill a cup with ice 
(preferably crushed), then add water and a 
teaspoon of salt to make a slush. Mix thor-
oughly and allow to sit for 2 to 3 minutes. 
This will give you a 32*F reference.  Now, 
lower the sensor into the mixture and leave 
for about 1 minute, then check the resis-
tance.  It should be very close to 13,300 
ohms.  Before reinstalling the sensor, be 
sure to rinse it with fresh water and dry it. 

REMOVAL OF DISPLAY

 

Hold the Ice & Water  select tab and pull it  forward to take off    
the Display Panel.  

WHEN ASSEMBLING COVER DISPLAY                                                                                                 

First insert it from the left side, then assemble to the right side.                                            
Otherwise the hook can break.
