Sensors
Defrost – The sensor voltage tells the Main PCB to turn off the
Defrost Heater At 50
o
in Freezer, 63
o
in Fridge
Compartment Temp – The sensor controls fan/compressor on/
off to maintain temp
Ice Production – harvests when the I/M sensor reads 1.5 de-
grees for 5 minutes, Flex Tray Only.
If the door is opened during that 5 minutes harvest is delayed.
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 Accurately
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 thoroughly and allow to sit
for 2 to 3 minutes. This will give you a 32*F refer-
ence. Now, lower the sensor into the mixture and
leave for about 1 minute, then check the resistance. It
should be very close to 13,300 ohms. Before reinstall-
ing the sensor, be sure to rinse it with fresh water and
dry it.
Ranges of ambient temp. Operation
Above 66 ℉
Condenser-Fan is ON as soon as the
compressor is on.
61 ℉ ~ 65 ℉
Condenser-Fan is ON with 5 minutes
delay from the compressor on.
Below 60 ℉
Condenser-Fan is OFF regardless of
the compressor operation
