DOOR DISPENSER CONTROL INPUT OPERATIONS

Side-by-side models equipped with an ice and water dispenser through the refrigerator door utilize a capacitance
touch control panel similar to the main control panel. Below are the input operations a customer or Service
Technician may perform at the door dispenser control panel.
The dispenser assembly operates on low DC voltage. Never apply AC line voltage to the dispenser compo-
nents, doing so will damage the appliance.

Changing the Dispenser Lighting States

There are three possible lighting states at the dispenser assembly:
• All Lights ON (blue keys and white glasswell)
• Key Lights ON only
• All Lights OFF
Touch the LIGHT key in multiple key strokes until the desired lighting
state is achieved (See Figure 2-30).
NOTE: During water or ice dispensing, all lights will illuminate until dis-
pensing is complete, then lights will return to their previous state.

Dispensing Water

To operate the water dispenser, set a glass on the grille of the glass-
well, then touch and hold the WATER key until the desired amount of
water is received (See Figure 2-31).
NOTE: Before the water dispenser is used for the first time, or after
servicing the water dispensing system, the water reservoir tank, water
lines and plumbing connection must be purged of air. Do this by touch-
ing the WATER key three (3) consecutive times for one (1) minute each.
Do not touch the WATER key for three (3) straight minutes, as this will
cause the "H2 L0" error and the dispenser will stop working.

Dispensing Ice

The ice dispenser in these models uses a delay, or metering feature to
limit the amount of ice dispensed each time the ICE key is touched in
approximately two (2) second intervals.
To dispense ice, set a glass on the grille of the glasswell, then touch
and hold the ICE key for approximately two (2) seconds, and the dis-
penser will meter out the ice, collect it in the cylinder valve directly
above the glass, then turn the cylinder valve to drop the ice into the
glass (See Figure 2-32).
If less ice is desired, hold the ICE key for less than two (2) seconds; if
more ice is desired, hold the ICE key until the dispensing cycle repeats.
NOTE: The ice dispenser can be reprogrammed to deactivate the delayed dispense feature, which would allow the
dispenser cylinder valve and ice auger motor to remain energized continuous whenever the ICE key is touched and
held. This is referred to as Delayed Dispense Reset, and is covered on the next page.
