Note:  

1) Cut-on, cut-off, and cabinet temperature are read by the same sensor, called the 

"cabinet thermistor." 

2) The defrost thermistor reads the evaporator temperature.
3) The drain tank heater stays on until the drain tank thermostat is satisfied. If the 

thermostat is satisfied within the first five minutes, the heater will continue to cycle 
on and off until the thermostat is satisfied past the five minute mark.

4) The evaporator fans turn off when the door is opened.
