1.4 after Servicing
After servicing the unit, whether at a site or service center, check the following:
MAKE CERTAIN THERE ARE NO LEAKS IN THE DRAIN OR WATER LINES. Check the water line, water valve, drain valve, and drain •
tubing for leaks.
Make certain the Ice Maker functions properly by observing ice production and ice harvest cycles. Check for hollow ice slabs •
or ice slabs that will not release.
Make certain the bin thermostat will turn the unit off. The best way to check this is to let the Ice Maker bin fill with ice. How- •
ever, if time is restricted then use several ice cubes and place them on the bin thermostat’s capillary tube sleeve located on
the side of the ice bin. The unit should shut down within a few minutes. After removing the ice, the unit should start at least
five minutes later.
