evaporator.
Ice Maker Suction Line Thermistor Removal
The suction line thermistor is mounted to the suction line
coming from the fin and tube section of the ice maker
evaporator. The thermistor is mounter inside foam
insulating tape and senses temperature of the suction
line and relays this information back to the control board
for EEV operation. (See Figure 6-86)
To replace the suction line thermistor (T3), disconnect
power from the unit and remove the side plate. Remove
the thermistor from the suction line and disconnect the
wiring at the connector.
NOTE: It is critical to proper operation of the EEV valve
that the thermistor is mounted at the bottom of the
suction line.
