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.
